From: Margo Schulter (2007-10-12) Subject: Metastable intervals Dear Tuning List Friends, Please let me say how delighted I am to read the discussions about the paper which David Keenan and I wrote in the year 2000 about metastable intervals, an endeavor in which it was a great honor to participate. It is a pleasure to see the paper very ably updated. As it happens, the past seven years have given me an opportunity to explore some of the issues raised in that paper further, for example in the Peppermint 24 system (an offshoot of Keenan Pepper's famous "Noble Fifth" tuning which so agreeably played a role in our paper) and also the newer Zest-24 modified meantone system derived from Zarlino's 2/7-comma temperament. I hope that Dave's enthusiastic contributions here and elsewhere will spark much constructive discussion, and look forward to joining in an exploration of some of the ramifications of our paper. Most appreciatively, Margo Schulter [email protected]
From: Margo Schulter (2007-10-12) Subject: Zest-24 system: music and papers Hello, everyone. Given the recent discussions both on the meantone era and metastable intervals, I thought I might post some links to musical pieces and papers relating to a tuning system bringing these things together: Zest-24, the Zarlino Extraordinaire Spectrum Tuning. Before giving the links, I should quickly explain that in this tuning, there are two 12-note modified meantone circles, each of which can serve as a circulating temperament in itself. Within each circle, eight fifths (F-C#) are tempered in Zarlino's 2/7-comma (695.81 cents), while the other four are tempered equally wide (708.38 cents). The two circles are placed at a distance equal to the enharmonic diesis of 2/7-comma (50.28 cents). Note that many of the intervals are identical to those of a regular 24-note version of Zarlino's meantone, but others are different because of the irregular temperament to close each circle.

Subject: Zest-24 metastable intervals
Hello, everyone.
Many thanks to Dave Keenan for his list of metastable intervals. I
thought that I might see how many these are available in the Zest-24
system. Everything here follows his list, except that I've added a
"narrow supermajor sixth" at 923 cents. Also, I might term the
interval at 448c as both a "wide supermajor 3rd" and "narrow sub-4th,
but will here follow Dave's table.
If the nearest equivalent to one of these metastable intervals in
Zest-24 is more than about four cents from the Phi-mediant value, then
I have used brackets to emphasize this degree of variation. As we
point out in our paper, a Phi-mediant is not a precise point where we
expect something "special" to happen, but rather a guide to the region
of a plateau of complexity. However, I tend to assume that a
difference of five cents or more could cause a more appreciable change
in shading or color, and therefore is worthy of an alert to readers.

Subject: Meantone and modal color
Hello, everyone.
Please let me warmly take note of recent discussions on meantone
and related topics, which have lent me impetus to consider some
questions of "modal color" in the Renaissance and Manneristic
eras. As is very aptly observed in that thread, remote modal
transpositions involving "unusual" intervals around 1600 or
a bit later are very relevant to the question of "key character"
traditions of a later era oriented to a major/minor system.
For anyone seeking an understanding of meantone aesthetics, both
historical and modern, I would warmly recommend the writings of Doug
Leedy, which combine much erudition, fine musical judgement, and
eloquent advocacy.
While my main focus is on the late 15th to early 17th century, it
is fascinating how modal and tonal concepts interact in what might
be called the early tonal epoch around 1670-1730. Joel Lester's
book _Between Modes and Keys_ is a fascinating survey of the
situation in German from around 1592 to the mid-18th century.
The French literature around 1700 concerning "transposed modes"
that I mention below is intriguing, as are the modal organ
compositions of Chaumont (1695) for a temperament ordinaire
with nine regular and three wide fifths. Tempering the major
thirds slightly wide, with the regular fifths at around 1/5-comma
or 2/9-comma, would make the system circulate (i.e. no Wolf fifth).
A concern is that possibly I have written less of a coherent essay or
presentation than a table of contents for a treatise <grin>. Maybe the
best remedy is to say, early and often: "Please feel free to jump in
and ask questions or make comments at any point."
* * *
To me, the "meantone era" means especially the period from around 1450
to 1670 when this style of tuning (regular or sometimes modified)
nicely fit a style of modal polyphony based on a tertian ideal of
sonority (established by the 1520's or so), and also with many
characteristic accidental inflections often borrowed from the very
sophisticated medieval technique of the 14th century where the
complete trine (2:3:4) is the complete stable sonority.
However, I realize that meantone retained an important role in the
early tonal era (say 1670-1750), and indeed beyond, even as
circulating well-temperaments gained in popularity.
For me, the modal meantone era is a panorama of practices, a time when
traditional medieval patterns and concepts like intensive and
remissive cadences, and routine inflections, get used in new ways, and
sometimes reshaped to fit the new aesthetic of pervasive tertian
sonority, with subtly controlled shades of tension, as opposed to the
older dynamic contrast of stability and bold instability.
Thus the question of "modal color" can be an intricate one, because we
must consider not only the process of transposing the regular notes of
a mode, and the fluid nature of B/Bb, but also the routine or
sometimes not-so-routine inflections required to form intensive or
remissive cadences on various steps of a mode. This modal situation is
somewhat analogous to that of Near Eastern maqam and dastgah
traditions, where likewise certain accustomed inflections are part of
the routine "procedure" of a mode, nicely expressed by the Arabic
_sayr_ or Turkish _seyir_, i.e. the "path" followed the music.
Here we have a kaleidoscopic picture, in part captured by known
compositions themselves, in part reported by theorists (often of
diverse tastes and opinions!), and in part very imperfectly inferred
from this incomplete evidence. Why don't I outline a few points for
discussions, and eagerly invite anyone reading to seek clarification
of not-so-transparent points or definitions of unfamiliar terms and
concepts:
(1) Interestingly, the "standard" accidentals of Eb, Bb,
F#, C#, and G# seem common to much 14th-century and
16th-century music, in part because both periods tend
to use the same manners of cadencing, intensive or
remissive. on the same steps. Thus intensive cadences
with ascending semitones are common on F, C, G, D, and A;
and remissive semitones with descending semitones on E,
A, and sometimes D. In 1350 or 1550, a 12-note keyboard
tuning of Eb-G# nicely serves this system of modes or
octave-species and inflections -- albeit Pythagorean
in the earlier period and meantone in the latter.
(2) In the trinic focality of the 14th century, where the
restful and conclusive goal is a complete 2:3:4 trine
on the final of a mode or octave-species (e.g. D-A-D),
inflections serve mainly to alter unstable intervals
so as to make them "more closely approach" their stable
goals: for example, minor third before unison, major
third before fifth, major sixth before octave. Thus we
have intensive (E-G#-C# before D-A-D), or remissive
(Bb-D-G before A-E-A) manners. Many of these progressions
play a role in guiding the tertian textures of the 16th
century also, as does the intensive/remissive contrast,
noted by Tomas de Santa Maria in his treatise of 1565
on keyboard counterpoint and harmony. Of course, this
intensive/remissive theme of late medieval focality
takes new shapes in the meantone era.
(3) Additionally, by the 1520's, 16th-century technique
demands the regular use of accidentals to obtain
major thirds or tenths above the lowest voice of
sonorities of repose, as at final and also internal
cadences. This is one very strong reason for
adapting Eb-G# rather than Ab-C# as a usual 12-note
meantone: we need the major third E-G# for a close
in E Phrygian including the third. A love of what
Zarlino will describe as the harmonic division of
the fifth with the major third below the minor,
in frequency ratios 4:5:6, will invite many colorful
effects and inflections, including some forms of
direct chromaticism.
(4) One school of 16th-century and early 17th-century
thought is that ideally, at least, one should strive
to maintain smooth and "correct" meantone intonation
either by avoiding remote transpositions which will
place modes and especially their characteristic
cadences where the regular steps and inflections
will not be available on a given fixed-pitch
instrument; or, using an extended instrument
(anything from 13-16 to 31 notes) that will provide
those remote steps and accidentals in their usual
proportions. This is the view of Zarlino (1558), who
cautions that people writing modal transpositions
should consider the intended instrument or ensemble
and its possible limitations (not applying to singers,
of course). Praetorius, 60 years later, urges that
a meantone keyboard (1/4-comma) with 19 notes will
make available correct thirds such as F-Ab which are
missing on 12-note instruments in a usual Eb-G#.
(5) Another approach is to modify a 12-note tuning so
as to accommodate at least some locations where one
may be especially tempted to extend the system,
for example G#/Ab and/or Eb/D#. This approach is
documented as early as 1511 by Arnold Schlick, indeed
in the first practical guide on how to tune a keyboard
instrument (more specifically the organ) in a meantone
style of temperament. In Schlick's system, Ab is
somewhat compromised so as to serve as a tolerable
G# in ornamented intensive cadences on A. Praetorius
describes a similar compromise in 1618, a bit more
than a century later; and at the end of the 17th
century, Werckmeister exhorts those still enamoured
with the "Praetorian temperament" (i.e. 1/4-comma)
to at least consider this kind of finessing for
Eb/D#, for example.
(6) While authors such as Ramos (1482) and Denis (1643,
1650) emphasize that one must not play "bad" meantone
intervals, for example augmented seconds or diminished
fourths in place of regular thirds, others such as
Lanfranco (1533) tell us that C# and F#, for example,
are sometimes used as Db and Gb. This might imply
either the frank acceptance of some of the intervals
that Ramos and Denis warn us against, or a subtle
"mollification" of these intervals through a bit of
finessing (see point 5 above).
(7) Around 1700, the French literature speaks of
"transposed modes" in the sense of those involving
unusual intervals in a regular or modified meantone
tuning, and reports that some musicians find them
all the rage; the keyboard music of Couperin, as
analyzed by Lindley as neatly fitting a temperament
ordinaire, accords well with such observations.
While by this point we are moving into the realm
of early tonality, such a taste for unusual
intervals might also fit the sensibilities of late
Manneristic modality around 1600, along with the use
of new dissonances and chromatic idioms.
(8) In the performance on keyboard of a written
composition, unusual meantone intervals may occur
either if they are expressly written (e.g. D-Bb-F#
or E-G#-C), as may occur in conventional as well as
"experimental" 16th-century styles; or if sonorities
with regular spellings are performed with accidental
substitutions (e.g. written B-B-D#-F for an intensive
cadence to E realized B-B-Eb-F; written Ab-C-F-C for
a remissive cadence to G realized G#-C-F-C). How
often might performers accept the latter situation,
or possibly even relish its colorful consequences?
Lindley suggests that composers might sometimes
anticipate such a situation by writing D# to form
an intensive cadence on E, for example, but with
ornamentation to soften the vertical impact -- much
as Schlick had done with G# in his organ composing
when making an intensive cadence on A.
(9) From a modern xenharmonic perspective, neomedieval
or otherwise, the septimal approximations produced
by unusual meantone spellings can be a special
attraction. However, we should be aware that while
some musicians of the period such as Fabio Colonna
loved a range of unusual intervals and intonations,
a specific taste for septimal ratios and intervals
as an asset of meantone may first be articulated
by Huygens (1691) in his famous essay on the new
31-note harmonic cycle. It is a signal for due
caution when Vicentino (1555) finds the augmented
second or "minimal third" likely near 7:6 (in a
circulating 31-note 1/4-comma or 31-EDO) to tend
toward dissonance, and the augmented sixth likely
close to 7:4 as also on the dissonant side -- in
contrast to the neutral or "proximate minor" third
which he states is close to 11:9, and finds rather
concordant. Taking into account both Vicentino
and Huygens leaves open the possibility that
tastes might vary at any point in time.
(10) Looking at this situation from a 21st-century
perspective, we may be influenced in our view
of the meantone era by a familiarity with either
the earlier medieval or later tonal practice,
not to mention elements of other world musics.
It is fascinating to try and sort out both the
historical evidence as to the sonorous worlds
that may have obtained during this engaging
era, and our own "alternative histories" that
may be inspired by this era at once luminous
and nebulous.
Again, I welcome questions, comments, or requests for clarification on
any of these maybe not-so-easily comprehensible points, a great help
for me in trying to state things more coherently.
Most appreciatively,
Margo Schulter

Hi, Cameron and Dave.
Thanks to both of you for a discussion which has inspired me to a
project of recording some of these metastable intervals and their
typical resolutions in Zest-24. That may take a day or so, but in the
meantone, or meantime, why don't I comment briefly on what I suspect
the issue may be.
Here I'd want to make a distinction between a general discussion on
musical aesthetics or style, where distant or soft consonance sounds
to me often very evocative; and the rather narrow although interesting
context of a technical discussion on harmonic entropy or complexity.
In the latter, "consonance" tends to have a customary meaning of
"harmonic simplicity" or "coinciding partials" or the like, so that
indeed it could "cause a lot of confusion" if the same term were used
for maxima of complexity also. At least, I'd agree that one should be
aware of the potential conflict of meanings in this specialized arena
of discourse.
One simple solution which should avoid any potential confusion is to
use qualifying quotes. Thus:
While a 287-cent minor third is quite near the
zone of maximum complexity as suggested by the
Nobly Intoned (NI) value of around 284 cents,
I find it quite "consonant" and sweet.
Personally what I might advocate to avert this kind of semantic
complication is to use some other term than the often-charged
"consonance" for harmonic simplicity, coincidence, or smoothness.
However, given the very widespread technical use of this term by
Sethares and others, I'd suggest that in a harmonic entropy or
complexity discussion, we let metastable intervals be euphonious,
pleasing, or even concordant -- but "consonant" with the quotes.
In other contexts, where consonance/dissonance as well as
concord/discord are concepts perennially up for grabs, those quotes
seem to me unnecessary.
By the way, I wonder if maybe, in the harmonic entropy kind of
context, we might want a term like "assonance" (that came up once, I
seem to recall, in a discussion where Heinz Bohlen was involved) or
even "isonance," the latter meaning a kind of uniform or pervasive
non-coincidence of partials described by Professor Temes.
With many thanks,

From: Margo Schulter (2007-10-14) Subject: Re: Meantone Dear Tom and Johnny, Thank you both for a discussion which led to my own long post as a kind of spinoff, but also raises other issues worthy of much discussion. First, Tom, I agree with your observation that different shades of meantone temperament will have different qualities. The point about the contrast between pure major thirds and slightly impure minor ones in 1/4-comma is something Mark Lindley suggests could add special interest to passages in parallel thirds. As for 2/7-comma, which I mostly seem to be using in a modified form (regular in the range of F-C#), I would agree with Lindley that it may be ideal for rather moderately paced music, and also for music putting a good deal of emphasis on modes favoring the arithmetic division of the fifth where the minor third is placed below the major. The big point about meantone I might emphasize, as does Jean Denis in his treatise in the editions of 1643 and 1650, is the inequality of the diatonic and chromatic semitones: 117/76 in 1/4-comma, and 121/71 in 2/7 comma. Even when no "special" intervals or direct chromatic steps are used, as in a beautiful piece of Viadana I much enjoy, the routine juxtaposition of different inflections of a step (e.g. F#/F) can make this "enharmonic difference," as I recall Dave Keenan calls it, vital. For me, and also Denis, the difference in semitone sizes is of central importance. Reacting to people who wanted keyboards tuned equally (i.e. in 12-EDO), like the lute Denis said that rather this people might better use their ingenuity to improve the tuning of the lute by giving it proper major and minor semitones like the organ or harpsichord! Easley Blackwood also makes this point: meantone chromaticism has the special charm of those dramatically unequal semitones, which just doesn't translate into a 12-EDO rendition. Johnny, I certainly agree that we shouldn't neglect irregular temperaments other than "circulating well-temperaments." Lindley, for example, emphasizes that Schlick's temperament would have had at least what I'd call a "semi-Wolf" at C#-G#/Ab, about 8-10 cents wide, and which Schlick himself urges we avoid. Finessing only one or two notes in 1/4-comma like G#/Ab or Eb/D#, as described by Praetorius and advocated by Werckmeister for those not interested in a circulating well-temperament, would be unlikely to repair the Wolf fifth, although it might alleviate it a bit, say to something like 1/6-comma. The Grammateus temperament is a bit different, because that is primarily based on Pythagorean tuning with diatonic whole tones divided into two equal semitones -- that is, each equal to 9:8^(1/2), or about 101.955 cents (e.g. F-F#-G); E-F and B-C are the usual 256:243 or 90.224 cents. Jorgensen considers this as circulating, with two fifths at 1/2 Pythagorean comma narrow, or just on the verge of being Wolves by this definition. Maybe, like Schlick's, it could be called "semi-circulating" -- but not necessarily by intent, as far as I know. Dowland's irregular lute tuning is also interesting, and that has at least one Wolf fifth, as I recall. A final point I'd like to clarify is that 31 notes per octave in 1/4-comma is a very nice circulating system, much like 31-EDO, with the subtle difference that some intervals will differ in size by about 6.07 cents, the difference between 18 pure octave and 31 1/4-comma fifths. This variation will affect only a few major and minor thirds, and is, of course, milder than that typically found even in quite subtle 12-note well-temperaments.

Subject: Re: A question
Dear Shaahin,
Please let me suggest that if you are looking for a tetrachord
covering a tritone of some kind, the European Lydian mode might be one
example. Actually, these four notes are part of a pentachord covering
a perfect fifth:
--------------------
F G A B C
------------------------
Also, at first I thought you might want a tritone formed with four
_interval steps_, and there a Buzurg arrangement of the fifth might be
interesting, as described by Persian theorists around 1300, maybe
specifically Qutb-al-Din al-Shirazi, again with the tritone actually
part of a "pentachord" with a perfect fifth (here actually five
intervals or six notes):
0 128 359 498 626 702
1/1 14/13 16/13 4/3 56/39 3/2
14:13 8:7 13:12 14:13 117:112
128 231 139 128 76
Note that the lower tetrachord could be a permutation of Ibn Sina's
1/1-14/13-7/6-4/3, with its steps of 14:13-13:12-8:7.
In 96-EDO, we might do something like this for Buzurg:
0 125 362.5 500 625 700
125 237.5 137.5 125 75
or maybe this, with a large whole-tone step slightly narrow rather
than wide of 8:7,
0 137.5 362.5 500 625 700
125 225 137.5 125 75
More generally, we might notate the basic pattern of Buzurg, however
tuned, as this: C Dp Ep F F# G.

Hi, Cameron, and that's a valid point. The strange spot around 284 cents, by the way, coincides with 33:28 (284.447 cents), for whatever reason. I tend to think of something around 287 cents as a kind of tempered compromise between 33:28 and 13:11. >Hi Margot!

Considering this, I'd agree that "isophones" or "isonance" runs into a possible confusion with isoharmonic sonorities or chords, which have a ery clear and accepted meaning (e.g. 7:9:11:13). However, your "xenophones," or maybe xenonances, looks perfect. These nobly intoned (NI) intervals, as Dave has named them, are indeed "strange" ones at ratios maximally distant by at least one possible mathematical measure from the familiar realm of simple ratios with coinciding partials. What I like about "xenonance" is that it tells us that this is definitely something different, but doesn't impose any viewpoint as to just how we should hear it -- as concord, discord, or something else. It also has a pleasant association with the "xentonality" of Bill Sethares. >> With many thanks > , rather, thank you, Margot!

You're right, and I hadn't even considered an 88-EDO version. Looking at this in Scala, I saw how indeed, while Zest-24 has closest approximations to 7/4 at around 963 and 975 cents, with 88-EDO we get 968.182 cents, virtually just! With such closely related versions of a tuning, people could be drawn to subtly different shadings for a range of reasons -- as with the quest for the "ideal" degree of meantone.

However, Wilson's Metameantone is quite comparable to your 88-EDO version, and that 7/4 makes 88-EDO a logical spot to choose in this neck or niche of the woods. Best, Margo

May I assume that "keys" here means simply the number of locations in
a tuning with a fifth plus a major or minor third of an acceptable
size for a given style? What I'd like to do is to look at Schlick from
a few stylistic angles, including Schlick's as far as we can tell, in
a way that might address some of the issues of the counting process.
I must admit I don't know what Fischer's temperament from the Bach era
is, but I'm very interested to learn. Why don't I give a Scala file
for one reading of Schlick (1511), based largely on Lindley's analysis:

First, let's consider the fifths: 11 locations have fifths within
about 5 cents of pure, with C#/Ab as the semi-Wolf or "dog" at about
8-10 cents wide according to Lindley. In a medieval style, where major
and minor thirds are unstable and flexible in their tuning, and thus
not an essential element in defining a stable polyphonic center, we
have 11 locations for transposing any desired mode -- as long as that
pesky "dog fifth" doesn't "bark" on a degree where we need a stable
fifth, like the confinal or reciting tone. Actually that canine might
be very exciting and charming if it occurs between two upper voices in
the unstable sonority E-G#/Ab-C# leading to a cadence on D-A-D!
Indeed, Lindley says (and I agree) that in this kind of medieval
cadence, the upper fourth of that unstable sixth sonority might be
impure by a full Pythagorean comma!
However, for medieval or neomedieval purposes where "circulation"
means simply that all 12 fifths are within maybe 7 cents or so of pure
(as in 19-EDO, or 22-EDO with tempering in the opposite direction),
it's easy to achieve full circulation simply by lowering Ab/G# about
two or three cents, so that Ab-C and E-G# are about equally impure,
each somewhere 404 cents. This doesn't have to be precise, and here
I've simply picked one possibility that still favors Ab-C a bit:

Now let's go back to Schlick's temperament itself, viewing it from his
own stylistic perspective in an early 16th-century context. Now thirds
as well as fifths become factors in defining a good modal center. By
Schlick's own criteria, we have 8 locations with reasonably agreeable
major thirds, Ab-C less smooth than the others but still acceptable
for sustained use (maybe around 12-EDO size).
At around Pythagorean, E-G# is unstable but tolerable for use in
ornamented intensive cadences to A (with an ascending semitone G#-A);
B-Eb, F#-Bb, and C#-F are like typical meantone diminished fourths,
here maybe 413 cents or so, in the zone Secor has discussed between
Pythagorean and the region of 14:11 (418 cents) or a tad wider where
listeners might still hear some semblance of relatedness to 5:4 in
styles where it is the ideal. Writing in a 16th-century context, not
surprisingly, Schlick tells us that they are "little esteemed and
seldom used" -- but maybe also, one is tempted to guess, not
categorically excluded, at least for the more adventurous transposers
whom certain theorists either mention without reproach (Lanfranco
1533) or passionately warn us against (Denis 1643, 1650).
Thus we have 11 stable fifths, and 8 stable centers for modes
featuring major thirds above the final (Lydian, Ionian, Mixolydian) --
assuming that the C#-Ab/G# "dog" or those 4 major thirds at
Pythagorean or larger don't disrupt other steps where we need stable
tertian sonorities. How about modes with minor thirds above the final
(Dorian, Aeolian, Phrygian)?
Here things are more problematic, because we don't know Schlick's
criteria for minor thirds. If we embrace one modern view that the
tuning of these intervals is very flexible -- like major thirds also
in a medieval rather than Renaissance/Manneristic context -- with
anything from around 7:6 to 6:5 acceptable, then we have potentially
11 locations for these modes, everything except for C# with that dog
fifth. Again, once we consider other steps of the mode and cadences,
it will get more complicated.
If we instead say that a minor third shouldn't be "substantially"
smaller than Pythagorean, based on theorists who outright reject
meantone augmented seconds used as normal minor thirds (e.g. Denis),
or at least urge great caution (e.g. Vicentino, 1555), then we have 8
such minor thirds at locations with acceptable fifths, here including
Ab/G#-B-Eb with the minor third at around 291 cents, or three cents
narrow of Pythagorean. This leaves Eb-F# and Bb-C# at 285 cents or so,
outside the range of musical interchangeability under this criterion.
It's interesting to ask how a composer like Josquin might take to
playing something like his beautiful _Mille regretz_ in Eb Phrygian
with the third above the final Eb-F# at around 285 cents. Would it
sound too far from the new meantone ideal -- or possibly quite
congenial to the older Pythagorean tradition still in evidence around
1500, where it could add to the melancholy quality of the piece: a
touch of "modal color" analogous to the key color that French writers
about 200 years later describe for very small minor thirds in a
temperament ordinaire?
Unfortunately, Eb Phrygian becomes rather academic because of that
pesky dog fifth on C#, the step below the final, although that step is
less prominent than in lots of Phrygian settings. If we're going to
try it, I'd say let's lower Ab/G# a bit as in my variation, which
wouldn't affect the size of Eb-F# or Bb-C#, our smallest minor thirds.
My point is that counting acceptable modal or tonal centers can be
very sensitive to what people are assuming is "acceptable," and also
that having "8 locations with an acceptable major third and fifth; and
9 with an acceptable minor third and fifth" is only the first step in
deciding how many of those locations would also accommodate the
confinals, usual internal cadences, and so forth for a typical piece
in Dorian, say.
Let's illustrate this moving ahead a bit in the 16th century, to the
1520's and later. How about untransposed E Phrygian, or A Dorian for
that matter? With either, we encounter a very basic problem: a closing
sonority with a third above the final -- or likewise a sectional close
on some other step of the mode -- is by this point expected to be
major, by inflection if necessary. A Pythagorean E-G# thus makes an
up-to-date Phrygian untenable, and likewise modes like A Dorian which
often have internal cadences on E (here the confinal).
Anyway, as far as the fifths go, there's only one "semi-Wolf" in
Schlick's temperament, C#-Ab/G#. It's a situation where we have a
harmonic excess from the 11 notes or 10 fifths Eb-C#, with the six
diatonic fifths F-B maybe around 1/5-comma and the other four around
1/6-comma according to Lindley, of something like 12 cents. The
"finessing" involves the single note Ab/G#, with Schlick evidently
making Ab-Eb about 2-4 cents wide (thus comparable to some of the
narrow fifths), and leaving 8-10 cents for our C#-Ab/G# "dog." A
division of this excess more like 5/7 cents or 6/6 cents would make
all fifths fully circulating.
Again, I'm very curious about the Fischer temperament and how it might
compare to this one.
> I have seen the use of the term "dog-fifths" for these (for being
> more tame than wolves...instead of howling, they merely bark).
Yes, I have seen someone, Bradley Lehman maybe, compare the Wolf in
1/6-comma to a "border collie." By the way, in discussing
"circulation," maybe it would be helpful to separate the wolves and
dogs from the goats, so to speak.
My idea is to use the canicular terms for fifths somewhat more than
1/3-comma from just: maybe "dogs" in the Schlick range of 8-10 cents;
"semi-Wolves" around 1/2 comma or a bit more (Jorgensen goes as far as
15 cents or so in certain circumstances); and outright Wolves beyond
that.
In contrast, "goats" are thirds appreciably larger than Pythagorean
(if major) or smaller (if minor). My inspiration for this is a French
term, _ton de la chevre_ or "goat tone or mode," evidently used by
around 1700 to describe a transposition like C# Dorian or Aeolian
(moving by this point into minor) with "bleating" major thirds in a
regular or modified meantone. While the term might actually have
originated to describe some kind of lute effect involving timbre
rather than supra-Pythagorean major thirds, it came to describe a
keyboard transposition with those extra-wide thirds.
Thus in a conventional well-temperament, the idea is to avoid both
wolves or dogs and goats; in a "fifth-circulating" temperament, as I
might call it, we might specifically seek to have meantone color over
a bit more than half of the 12-note circle while making the remote
region a peaceful pasture where goats may safely graze. The variation
on Schlick that I describe would thus be a fifth-circulating
temperament of the goat-friendly variety, but certainly _not_ a
"well-temperament"!

I'm pretty sure that it was in this article, only available via the
Internet through a subscription but very likely still at my library:
Bach's keyboard temperament
Internal evidence from the Well-Tempered Clavier
BARNES Early Music.1979; 7: 236-249
This is a very well-written article that considers the evidence in a
calm and balanced way, and shows an appreciation for the fine points
of unequal temperament. As I recall, the relevant passage (possibly
from the Orgelprobe?, if not from the work you mention) occurs in a
discussion where he mentions Zarlino's 2/7-comma, and shows that even
1/7-comma will have a dog fifth, as we're calling it, so that the
direction to circulation lies elsewhere. Then he describes how people
who are wedded to the Praetorian temperament could still benefit from
the concepts he is presenting by adjusting Eb (if I recall correctly)
so that it is also usable as D# -- in other words, a very rudimentary
temperament ordinaire. This is my recollection, at any rate. A trip to
the library could clear this up, and I'll try to do it in the next day
or two.

The count of "keys" or locations, for a modal or tonal style, could
depend on two main things.
First, we have 10 pure fifths plus two (Bb-F and B-F) impure by 1/2
Pythagorean comma. For Jorgensen, a "Wolf fifth" is anything _more_
impure than precisely this amount (11.73 cents) -- so these two make
it just under the wire, and he considers it a circulating
temperament.
Second, since all fifths are pure or narrow, we don't have any goat
thirds to consider. For Jorgensen, a major third is serviceable if not
significantly larger than Pythagorean, and a minor third at just about
any size from around 7:6 to 6:5 -- so we have all 24 locations
covered, 12 major and 12 minor thirds.
If we consider those semi-Wolves or dog-fifths too assertively barking
to be stable, then we have 10 rather than 12 locations available as
stable centers in a medieval type of context; as in lots of early
15th-century music, the different shadings of unstable thirds will add
lots of modal color, but are more or less freely interchangeable.
In part. Grammateus is offering a mathematical demonstration or
"amusing reckoning" for the sheer intellectual joy of showing how a
superparticular ratio like 9:8 can be equally divided by geometrical
means. Musically, however, the tuning seems to me to fit with an early
15th-century kind of outlook where the idea is to have a basically
Pythagorean system, but with some schismatic or allied thirds deployed
at certain strategic locations. In this view, fifth-circulation is not
the point, but splitting the Wolf fifth into two parts to combine the
remaining ten pure fifths with a larger number of "mollified" thirds
including one of these two semi-Wolves in their chains. An English
organ tuning of 1373 with an 18:17:16 division of diatonic whole tones
(e.g. C-C#-D) in a generally Pythagorean scheme might address similar
concerns, and would well comport with the penchant for 5-limit or
nearby tunings of thirds shown in some strains of medieval English
theory and practice, of which you have also spoken.
Putting the two semi-Wolves on steps a semitone apart (Bb-F, B-F#)
means that no fewer than 8 of the 12 major thirds will be so tempered
at about 396 cents, but creates a semi-Wolf at Bb-F which can create
problems with lots of late medieval music. Relocating these fifths to
locations like Eb-Bb and F#-C# (7 major thirds smaller than 400 cents)
or F#-C# and G#-Eb (6 major thirds smaller than 400 cents) gives many
of the same advantages with less disruption.
It is worth emphasizing that these variations, like the original
Grammateus tuning, really belong more to the musical style current
around 1400 rather than 1500, and do not address the needs of a style
calling for some variety of meantone. The diatonic major thirds F-A,
C-E, and G-B, for example, remain Pythagorean -- so that the system is
not in the same musical category as Schlick's.
This said, we may note that the problem for someone wishing to make
these systems fully fifth-circulating are quite different, also. With
the Grammateus modified Pythagorean system, we face the problem that
the Wolf simply cannot be shared between only two fifths while making
both fifths less impure than 1/2 Pythagorean comma -- one or both must
howl, or at least bark quite assertively! An equal division among
three fifths could be marginally acceptable, with four fifths much
better. The result would be akin to a well-temperament, but with pure
fifths and Pythagorean thirds in the nearer part of the circle, and
tempered fifths and smoother thirds in the more remote portion. This
pattern fits with 15th-century Pythagorean variations rather than with
either 16th-century meantone or an 18th-century well-temperament.
With Schlick, the harmonic excess is something on the order of
about 12 cents, so it's easy to have both fifths within 7 cents or so
of pure if that's the goal -- which it wasn't for Schlick, who
evidently wanted to compromise Ab-C as little as possible while very
partially taming the goat third at E-G#.

Here I'd urge that we sort out the wolves and goats. On the canine
side, I'd agree that it's very unlikely that composers are going to
cadence on a fifth which is assumed to be half a comma or more
impure. If we see a fifth Ab-Eb, I'd take that as a hint that the
piece is intended for an instrument which actually has both notes!
There's an interesting partial exception that seems likely in the
earlier 15th century, when we find keyboard pieces in places like the
Buxheimer Organ Book with cadences like this:
B C
F# G
D C
Totally routine -- until we note, as Lindley does, other stylistic
indications that the piece is intended for a regular Pythagorean
tuning with written sharps tuned as flats, Gb-B, so that the upper
fourth F#-B, or actually the augmented third Gb-B, is wide by a full
comma! However, given the consonances formed by both upper voices with
the lowest one, and also the cadential context where we _expect_
instability and excitement when major third and sixth expand to fifth
and octave, he and I agree that it can be quite pleasing in practice.
Maybe that's the exception that proves the rule, as far as these
canine fifths go. It might fit with the 14th-century observation of
Johannes Boen (1357) that either an augmented or diminished fourth can
become a "consonance by circumstance" (_consonantia per accidens_)
when an appropriate third is placed below it (D-F-B or E-G#-C) -- and
so, apparently, an early 15th-century Wolf fourth.
However, depending on the concept of "circulation" at issue, we could
be talking about only wolves and dogs, or also goats. Here are two
possible definitions I'd consider relevant to this discussion:
-----------------
Fifth-circulation
-----------------
A 12-note tuning may be considered fifth-circulating if all 12 fifths
are within about 1/3-comma or 7 cents of pure: major and minor thirds
may be of any size as long as this condition is met. In a very
colorful modified meantone, for example, they may often range from
roughly 5-limit or pental to septimal: 5:4-9:7 and 7:6-6:5 for major
and minor thirds respectively.
-----------------------------------------
Tertian circulation or "well-temperament"
-----------------------------------------
A 12-note tuning may be considered tertian-circulating or
well-tempered when these three conditions are all met:
(1) The tuning meets the requirements for fifth-circulation,
with all 12 fifths no more than about 7 cents from just;
(2) The diatonic major thirds F-A, C-E, and G-B are not
substantially further from a just 5:4 than the 400 cents of
12-EDO.
(3) There are no "goat" major thirds substantially larger than
Pythagorean, with around 409-410 cents (say 19:15, used in a
temperament by Aaron Johnson) as a possible bounding region.
Getting fifth-circulation in a modified meantone is easy, and for a
more moderate degree of temperament like Schlick's irregular scheme
can easily be done by finessing only one note -- he could have done it
if he'd wanted to, and the same goes for a regular 1/6-comma meantone
where we adjust one note to split the Wolf about equally between two
fifths. Around 1/5-comma or 2/9-comma, we need to adjust two notes and
have three fifths share the excess; while for 1/4-comma or 2/7-comma,
this involves three adjusted notes or four comparably wide fifths.
However, I'd agree that for tertian circulation or well-temperament,
Werckmeister is a great innovator -- the only recorded earlier schemes
that I can think of that would qualify would be proposals or purported
proposals (like the one attributed by Doni to Frescobaldi) to tune
keyboards in 12-EDO. Very basically, even if Grammateus had split a
Pythagorean wolf into three or yet better four equal parts, achieving
full fifth-circulation, it would address a medieval kind of style
rather than the imperatives of meantone so central to Werckmeister.
Here the crucial imperative is requirement (2): the nearest major
thirds should be 12-EDO or smoother, not the Pythagorean size so
effective for medieval or neomedieval music but exactly what Schlick
and others tuning regular or modified meantone around 1500 are seeking
to get away from! To people like Zarlino and Lippius a Pythagorean
third is not only unstable but just about "dissonant," although
Praetorius gives us evidence that some people were ready to tolerate
it in order to have some approximation of both Eb and D# on a 12-note
instrument, for example. It's one thing to hit this now and then for
some remote sonority or cadence, another to have it at some of your
most frequently used locations for a 16th-century modal or
18th-century tonal style.
As for colorful fifth-circulating modified meantones, emphatically
including mine, as well as Schlick's rather more restrained approach,
we encounter requirement (3) of well-temperament: no goat thirds.
Note that this rule does _not_ exclude all fifths wider than pure, as
long as they are discreetly deployed, as in some of Neidhardt's
temperaments or Aaron Johnson's, so that thirds don't go substantially
outside Pythagorean limits.
On the subject of goats, as opposed to wolves and dogs, these
indubitably _are_ used in conventional as well as experimental
16th-century writing where they are explicitly spelled as diminished
fourths, for example. Here there is a fine and calculated balance,
whether in a Spanish Psalm setting or in an avant garde madrigal by
Monteverdi. The interval is "cushioned" by occurring between two upper
voices; occurs in passing; or otherwise is treated with due
discretion, rather like a more conventional suspension dissonance.
The open question is how often people made keyboard transpositions
where these goat thirds were substituted for regularly spelled ones in
a composition, and also whether composers, for example of the English
virginals school, either desired or expected this to happen for some
pieces going beyond the spellings available on a 12-note
instrument. Denis goes to great length to warn about the perils of
such transposed modes, which suggests that the practice wasn't unknown
in early 17th-century Paris, at any rate. However, he associates it
with organists too eager to accommodate singers, a motivation not so
relevant to solo keyboard performances then or now.

Certainly I'd agree that this is in a different category from a
12-note modified meantone or the like, and maybe related to the
_tastini_ or alternative frets that Vincenzo Galilei tells us that
some lutenists used to improve the thirds.

Dave, how thoughtless of you! This is the last straw! :-( After all we've been through, and after the painstaking effort I made to explain the many obstacles to my being taken seriously, I'm really disappointed that you would stoop so low. Furthermore, your dogged insistence on firming up the seemingly endless details of minas, tinas, and innumerable other things relating to the semantics of the Sagittal notation have kept me from a much more important task: that of resuming work on the truly remarkable story of how the notation was developed. I must take this opportunity, therefore, to express my profuse apologies to those who faithfully followed the story through the end of Episode Two, only to be left hanging (for more than 3 years!) with the yet unfulfilled promise that the account was "to be continued." My patience has completely run out. I can't tolerate this situation any longer! Dave, there's still a way to redeem yourself. I've worked around the clock on a temporary short conclusion to the story that will help to set the record straight. I'll be sending that to you very shortly after I post this message, and I'll forgive you for your previous impositions if you'll put it on the Sagittal website, where everyone can read it. We'll all be looking for it soon, so don't let us down! --"George"

The pure minor third from the half-octave is a real plus for me using a 34 framework- I have 12 pure noble dark thirds and 12 pure 6:5s in the tuning I'm using at the moment. The "tempered" versions of both (it's a "WT") are consistent in sign, with all but two dark thirds coinciding with the third I measured in a whale song, 2 cents lower than the noble dark third. The tuning has two clunkers for these intervals, 4.6 cents off of the ideal but with the right sign at least. >I tend to think of something around 287 cents as a kind of > tempered compromise between 33:28 and 13:11.

Hi, Johnny. Looking over your post, I'd say that two factors may
be in play here. The first is that Schlick's temperament can have
different shades of interpretation, so people's numbers may
differ a bit. The second is that we may be using the term "dogs"
or "canines" a bit differently -- and each use has its own logic.

OK, what's happening here is that we were defining our "dogs"
differently. You are counting _wide_ fifths, by however much.
I am counting fifths far enough from pure in either direction to
constitute a "navigational hazard" to the style of music in
question.
Your usage has a natural logic behind it. A wide Wolf in meantone
is a kind of wild or howling canine. Thus even if a fifth in a
modified system like Schlick's is only three cents wide, we can
still think of it as a "domesticated canine," although it's no
hazard at all to navigation.
How about "poodle fifth"?
Maybe we could agree that Schlick has "one semi-Wolf and one
poodle fifth."
> J. Murray Barbour found different values for Schlick, making

Yes, he interpreted the tuning as fully fifth-circulating, and a
logical step toward 12-tET.

Certainly we agree that this is an irregular tuning; and if we
use "key" in a kind of neutral way, as Morley did, to mean simply
a location or transposition of a piece (modal or tonal), a bit
like the 17th-century French use of _ton_, variegation of keys or
modal transpositions is indeed what happens in Schlick.

A quick comment: in describing a tuning, I'd want to distinguish
my Wolves or semi-Wolves from my gentle poodles. A fifth 9 cents
off in either direction is going to stand out in a typical
meantone or WT context, and not pleasantly. A fifth 4 cents wide
is in my view no problem at all, and often about as far off from
pure as the usual narrow fifths in the other direction; if it
causes any problems, it might do so by breeding goat thirds
inappropriate to the style. (How's that for a mixed metaphor?)

Here I'm looking at this from what I'd take to be one meantone
era perspective. Where a meantone around 1/4-comma or 2/7-comma
differs from 12-tET dramatically is in the unequal semitones,
which really come out in 16th-century chromaticism; and also in
the "special effects" intervals like diminished fourths or
augmented fifths, etc. People around 1550-1650 were familiar both
with meantone on keyboards and 12-tET on lutes, and argued about
the virtues or vices of each system (Galilei, Mersenne, Doni,
Denis, etc.).
Certainly I understand your point that both meantone and 12-tET
provide uniform interval sizes as to the "usual" intervals, such
as regular major and minor thirds. As someone to whom "modern"
often means "around 1600," I give weight to those "unusual"
intervals, and to chromatic progressions as well. From a
perspective of 1750 or 1850, I can see your point. Someone who
likes the uniform sweetness of a meantone organ might conclude
that if we need a 12-note circulating system, let's at least make
everything as uniform as possible -- thus 12-tET.

That's a good question. Getting back to our "dogs," maybe we
could say that a "canine" is simply any fifth that is tempered in
the opposite direction from the prevailing one; or is
significantly impure in either direction in a just tuning. A Wolf
is deemed unusable; a semi-Wolf generally avoided; and a "poodle"
about as well-behaved as the other fifths tempered in the
opposite direction, or maybe even more so.
Actually I do have a term for a major second around 220 cents:
that would be a largish major second or whole tone approaching
the ratio of 8:7 (231 cents). To me 10:9 (182 cents) is small;
9:8 (204 cents) is middle; and 8:7 is large. I'm not sure about
animal metaphors, however.

Please let me say that I'm not a member of the "12-tET was
impossible in the 18th century on keyboards" school, and I have
great respect for Neidhardt. It's only fair to add that I'm more
familiar with earlier eras; but Neidhardt's craft, like Bach's
counterpoint, is something that almost anyone might admire.

Do you mean that given that Grammateus and Schlick are both
variegated, no one can tell these two tunings apart?
If so, I'd say let's take a keyboard prelude in an F mode, for
example, around 1500, and compare the 408-cent thirds at F-A,
C-E- and G-B in Grammateus with the same thirds somewhere around
390-394 cents in Schlick (say 1/5-1/6 comma). The first is
appropriate to a late medieval style based on some variation of
Pythagorean tuning, the second to a Renaissance style of the kind
that assumes meantone temperament.

Around 1600, meantone might not necessarily be associated with
"regularity" if we look at all the keyboard pieces celebrating
_durezze_ ("little dissonances") and augmented or diminished
intervals. People with split keyboards were often taking the
opportunity to relish rather than avoid these intervals.
Similarly, Artusi regarded Monteverdi as undisciplined for
writing C#-F (thus spelled) in one of his madrigals, although he
considered it fine on a 12-tET lute, and suggested that this
composer didn't know the difference! Meantone may mean different
things to different people in different periods.

Please let me quickly and concisely (for once!) clarify that I
was speaking specifically of a meantone instrument around
1/4-comma or 2/7-comma temperament. In a context where enharmonic
identity applies, as for many 16th-century lutes in 12-tET as
well as 12-note WT a la Werckmeister, my statement obviously
doesn't apply -- as you're very right to point out.
We much agree that enharmonic equivalence for keyboards is an
idea "which took big time" -- maybe a bit of an understatement.

Of course, we'll each have our own tastes, in tunings and in
categorizations of them.

Of course the example of the music of the First Nations has a
special force because here we're talking about a context of
ethnocide, ethnic cleansing, and often outright genocide.
More generally, as someone who strives both to teach history and
to create new "alternative history" (George Secor and Daniel Wolf
have written eloquently on this latter concept), I do feel a
responsibility in my writing not to confuse the second with the
first.

From: Margo Schulter (2007-10-23) Subject: Variegation of thirds and harmonic recycling Hello, everyone. Please let me share a link to a new paper on a style of 12-note circulating temperament which balances the Pythagorean, syntonic, and septimal comma to seek a variety of thirds from 5-limit to septimal: the temperament extraordinaire (TE). <http://www.bestII.com/~mschulter/TE1.txt> While some historical versions of the temperament ordinaire around 1700 might fit structurally into this category, I'd consider it mainly a 21st-century concept (unless people know of other precedents) because of the specific goal of some septimal approximations in the far part of the circle. As discussed in the paper, this kind of 12-note circle might be seen as a kind of fusion between historical meantone and the "17-tone revolution" which George Secor heralded with his 17-tone well-temperament of 1978, and in which I have delighted to participate with him. While George certainly shouldn't be held responsible for any dubious concepts or implementations on my part, his art and most admirable craft in scale design have been a great inspiration to me, and a principal source for whatever merits my concepts might have. This paper describes some basic aspects of the temperament extraordinaire and its strategy for obtaining a variegation of thirds through "harmonic recycling." Eight regular meantone fifths somewhere in the range from around 1/4-comma to 2/7-comma or even 3/10-comma do an amount of narrow tempering considerably overshooting the Pythagorean comma; and this "harmonic surplus" is "recycled" by four wide fifths which disperse the septimal comma for some approximations of 7:6, 9:7, 7:4, etc. While much of the paper focuses on musical purposes and stylistic contexts for this tuning approach, there's also an appendix that looks at some mathematical aspects of harmonic recycling, and how John Brombaugh's temperament units (TU) can be used in tracking the interplay of the three commas. Many thanks to all of you whose ideas and suggestions over the years have helped shape this project. By the way, I would be glad also to post the full paper here if people would like this, which might make for easier quoting (carefully selective, I would entreat!), but thought that given the length over 800 lines, a URL might be the best option, at least for now.

We discussed it only briefly, since there were other important pending issues that we needed to resolve.

Although it's possible to come up with enough one-syllable names for all of the single-shaft Sagittal symbols, solmisation (which is what I think you're interested in) would require a one-syllable name for every combination of natural nominal (A thru G) plus conventional accidental (sharp and flat alteration) plus Sagittal accidental (counting up and down as separate accidentals).

I recall that Fokker devised one-syllable Dutch names for all of the pitches of 31-equal, so that could serve as a starting point.

From: Margo Schulter (2007-10-25)
Subject: Wolves, poodles, goats, and styles
Hello, everyone.
Please let me comment very briefly on some issues where I would
consider it far more important for us each to be true to our own
musical traditions and practices, old and new, than to seek any
"standard" terminology.
Johnny, to me a "Wolf" or "semi-Wolf" means a fifth rather more than
1/3 syntonic comma impure -- with 1/3 Pythagorean comma (as in
Werckmeister IV) sort of pushing the envelope, but still just within a
"circulating" category. This is under the Scala reading where the most
heavily tempered fifths are around 694 and 710 cents; Paul Erlich was
willing to consider going this far under very different circumstances
to optimize septimal ratios for his "paultones" with fifths around
22-EDO, or possibly a bit larger.
If it's within 7 cents or so of just, I generally would simply call it
a "fifth" -- noting the direction of temperament where that is
relevant ("wide" or "narrow"). The new term "poodle" sounds very nice,
and I _would_ use it for a 707-cent fifth in a tuning where 697 cents
is the norm. As far as I'm concerned, the two are equally circulating.
Maybe this reflects my custom of quite routinely tempering fifths in
either or both directions -- all regular fifths wide in Peppermint or
a 17-note circulating temperament; all narrow in regular meantone; and
a mixture of eight narrow and four wide in my modified meantones.
Similarly, Charles, I regard a major third around 9:7 as routine and
desirable, and at the same time distinct from 5:4, rather as some fine
ornate typeface is distinct from a simple and smooth one. Juxtaposing
the two indiscriminately, in music or typesetting, is not necessarily
the formula for aural or visual concord. In a modified meantone like
the one I use, where all the fifths are comparably impure, I would
consider Db-F at close to 9:7 as the glory of Eb Dorian or C Phrygian,
where this third respectively contracts to a unison or expands to a
fifth; these modalities almost by definition call for a medieval or
neomedieval style. Of course, it also makes a striking and compelling
diminished fourth in a Renaissance meantone setting. The fun question
is which transitions or juxtapositions are pleasant and desirable.
Then, again, I'm ready to go rather further than 9:7 when it comes to
cadential major thirds expanding to fifths, with an article by Jay
Rahn about Marchettus of Padua as the basis for the following:
<http://www.bestII.com/~mschulter/PythEnharImprov01.mp3>
What I've decided is that making new music should be my first
priority, and offering some curious verbalizations about what I'm up
to, however imperfect and incomplete, a good next priority. That means
discussing lots of history, and making some alternative history, which
with a passionate enough immersion in both need be distinguished only
when convenient for certain pedagogic purposes. Those purposes often
_are_ relevant and convenient, by the way.
A quick final note on Werckmeister V: I'd call it a nice circulating
temperament, and note with curiosity that it achieves one goal also
important to my 2/7-comma temperament extraordinaire in a 16th-century
context: keeping major thirds on the six untransposed modal finals no
larger than about 396 cents. Of course, they are radically different
systems, and Werckmeister was presumably focusing mainly on tonality
around the end of the 17th century rather than polyphonic modality of
one kind or another.
Most appreciatively,

Johnny: If that was true for Werckmeister, he would never have suffered the
grief that he did in promoting WIII ahead of WIV. I can certainly accept
that you feel this way, and I speak more regularly with Paul as I’m planning to
do my Odysseus in Boston on May 4 and Paul is playing.
While I await a possible correction from Paul on WIV in C major, I believe
the historical situation for Werckmeister, who inherited his positions using
what he now call WIV, but which he credited to Trost and his unnamed late
cousin. My suspicion it is because Andreas was primarily recognized as an
improviser rather than a composer. I have been performing every Werckmeister piece
I can find, more recently his Praeludium in G from the Halle dissertation.
Most famously, the Christmas cantata Wo ist die neugeborne Konig auf den
Juden (PITCH 200202 Early).
Margo: If it's within 7 cents or so of just, I generally would simply call
it
a "fifth" -- noting the direction of temperament where that is

and I _would_ use it for a 707-cent fifth in a tuning where 697 cents
is the norm. As far as I'm concerned, the two are equally circulating.
Johnny: I suspect you have stretched ears. Werckmeister actually used the
word Circul to indicate the difference between WIII and WIV. (Sorry everyone
that the names of these prominent scales are so arcane.) What you like to
hear, or consider sounding nice, doesn’t change the facts. If one is allergic
to dogs, even the nicest, sweetest poodle would still cause an allergic
response. It may be one of the most amazing challenges, the ability to get into
someone’s head. Actors do it all the time. Musicians are often actors,
usually the best of them. Getting into the mind of a long dead person through
their writing may be toughest of all. As I said to Paul, I do not think the
literature portends the full story. At best it is a part of the story. The
literature is more interesting in its influence of later generations.
Margo: Maybe this reflects my custom of quite routinely tempering fifths in
either or both directions -- all regular fifths wide in Peppermint or
a 17-note circulating temperament; all narrow in regular meantone; and
a mixture of eight narrow and four wide in my modified meantones.
Johnny: Exactly, you have stretched ears. Me, too. That’s why I recognize
the condition. It’s no different than musicians being over sensitive to
sound in general. We have stretched our minds in to encompass dissonance as
consonance. The French take the just third of 386 cents and recoil in horror at
its dissonance (anecdotal).
Your later comments: “What I've decided is that making new music should be
my first
priority, and offering some curious verbalizations about what I'm up
to, however imperfect and incomplete, a good next priority” make total sense
as regards your intervallic reactions.

If we're attempting to map single syllables to pitches (nominals plus accidentals), then it might be better to use seven consonants for the seven nominals (A thru G) and use consonants for the accidentals (since there are more consonants than vowels). --George

Nanotemperament and Brombaugh's temperament units
A quick essay for Brad Lehman
-------------------------------------------------
Whatever mixed blessings synthesized sound may have brought to the
world of early European music and its modern performances and
derivative styles, this technology has introduced a quirk into the
process of tuning with curious ramifications: _nanotemperament_.
Here I'll try to explain this quirk, and show how John Brombaugh's
temperament units (TU) can sometimes help in evaluating the
consequences. Since it was a commentary by Brad Lehman to his
temperament spreadsheet that made me aware of these convenient units,
I warmly dedicate this modest essay to him.
There may be a certain paradox, Brad, in my dedicating this essay
about synthesizer tuning to you, above all a paragon of the craft of
tuning historical instruments by ear. Please let me emphasize that
this dedication is a token of deepest appreciation and indebtedness
which, however, should carry no implications as to how you might view
my curious methods and musical goals.
---------------------------
1. What is nanotemperament?
---------------------------
For many microtunable hardware synthesizers, the units of tuning are
rather coarse, on the order of 1-2 cents. Theoretically "regular"
temperaments often become in practice necessarily irregular, in order
to balance out the synthesizer tuning units.
A very practical example is my temperament extraordinaire based on
Zarlino's 2/7-comma meantone, with eight fifths (F-C#) in this regular
tuning, and the other four tempered equally wide. For more information
on this general style of temperament, people might wish to visit:
<http://www.bestII.com/~mschulter/TE1.txt>
In theory, at least, the meantone fifths should be narrow by about
6.145 cents, and the wide ones by 6.424 cents -- not that any tuning
by ear could be anywhere near this precise!
As it happens, I could not be this precise on my Yahama TX-802
synthesizer either. Here there are 1024 tuning steps per octave, so
that each is 1.171875 cents. An interval of 599 steps is a virtually
just 3:2 fifth (actually about 0.002 cents narrow), so that for all
practical purposes one may regard this fifth as pure.
Unfortunately, the desired narrow temperament for the meantone fifths
of 6.145 cents (2/7-comma) is not an even multiple of 1.171875 cents.
Our nearest approximations are either 5 steps narrow (5.859 cents);
or 6 steps narrow (7.0325 cents).
A serviceable compromise, however, is available: _nanotemperament_, or
introducing very small variations in the sizes of the theoretically
regular fifths in order to have them "average out" at about 2/7-comma
narrow. Specifically, a chain of three fifths each 5 steps narrow,
plus one 6 steps narrow, means an average tempering of about 6.152
cents, almost identical to the desired 6.145 cents.
Another way to gauge the accuracy of this "averaging out" is to
consider that a regular major third in 2/7-comma is about 383.241
cents, or 1/7 comma narrow of 5:4. Our nanotemperament produces a
third of 383.203 cents. Since there are eight of these narrow fifths
to be tuned, we can arrange them in two groups of four, so that any
major third with both notes within this accidental range will have
this size virtually identical to that of Zarlino's meantone. Thus:
F C G D A E B F# C#
-5 -5 -6 -5 -5 -5 -6 -5
The theoretically uniform tempering of the wide fifths, 6.424 cents,
likewise is not an even multiple of the 1.171875-cent synthesizer
unit, or very close to such a multiple. Again, the nearest available
amounts of temperament are 5 steps (5.857 cents) or 6 steps (7.029
cents).
However, a chain with two fifths at 5 steps and two fifths at 6 steps
wide produces an average temperament of about 6.443 cents wide --
again, almost identical to the desired size. Together, these four
fifths produce a major third (or meantone diminished fourth) at around
433.594 cents, as compared with 433.517 cents in the theoretical
version.
Now we come to an interesting decision -- or rather accident -- that
occurred in implementing this concept. For whatever reason, rather
than arranging the pattern of wide 5-step and 6-step fifths as evenly
as possible, I found myself with this situation:
C# G# D#/Eb Bb F
+5 +6 +6 +5
Here the two fifths tempered by 6 steps are placed adjacent to one
another. What I seem to recall is that I was thinking along the lines
of a traditional meantone chain, and going by the impression that the
more "remote" fifths on each end of the chain (G#-D#/Eb and Eb-Bb)
should be the more heavily tempered.
Only later did I note this slight "unevenness" and consider the
implications for the tuning. Such a consideration invites a convenient
measure which happens almost exactly to mesh with the synthesizer
tuning system: Brombaugh's temperament units.
-----------------------------
2. A (nano)temperament recipe
-----------------------------
In Brombaugh's system, there are 720 temperament units (TU) in a
Pythagorean comma, 531441:524288 or 23.460 cents. A syntonic comma at
81:80 (21.506 cents) is virtually equal to 660 TU; and a septimal
comma at 64:63 (27.264 cents) to about 837 TU, and almost exactly
to 836.75 TU.
On a synthesizer like the TX-802 dividing the octave into 1024 equal
steps, 20 of these steps are almost precisely equal to a Pythagorean
comma, or 720 TU; and one synthesizer step to 1/20 of this comma, or
36 TU (actually about 35.965 TU).
A tempering of 5 synthesizer steps will thus be equivalent to 1/4 of a
Pythagorean comma or 180 TU; and 6 steps to 3/10 of the comma or 216 TU.
We can use negative values to show temperament in a narrow or meantone
direction, and positive values to show temperament in a wide direction.
The following temperament recipe results:
F C G D A E B F# C# G# D#/Eb Bb F
-180 -180 -216 -180 -180 -180 -216 -180 +180 +216 +216 +180
Here 6 fifths at -180 TU plus two at -216 TU do a total of 1512 TU of
negative temperament, exceeding the 720 TU of the Pythagorean comma by
792 TU. The 2 wide fifths at +180 cents, plus the 2 at +216 cents, do
792 TU of positive temperament -- thus balancing the circle.
The obvious compromise in this arrangement, of course, is that some
narrow and wide fifths alike will be tempered at just over 7 cents
impure, a degree of temperament comparable to 1/3-comma meantone or
the almost identical system of 19-tone equal temperament (19-tET),
also known as a 19-note equal division of the octave (19-EDO). Among
regular tunings with wide fifths, 22-EDO is also comparable.
Given that this compromise is unavoidable on such a synthesizer if we
wish to approximate the 2/7-comma temperament extraordinaire, we might
ask if any benefits are derived from this necessity. Before addressing
this question, we should quickly mention an alternative.
To avoid having any fifths more impure in either direction than 180 TU
(5 synthesizer units), we could simply temper the 8 meantone fifths at
180 TU narrow each, and the other four fifths at 180 TU wide -- so
that each is tempered by 1/4 Pythagorean comma. This procedure would
yield a very nice temperament while keeping all fifths within 6 cents
of pure. Further, it would not require any nanotemperament, since a
fifth tempered at 5 synthesizer steps narrow or wide is for all
practical purposes tempered by 1/4 Pythagorean comma or 180 TU in the
chosen direction.
However, I must admit that using Zarlino's 2/7-comma as the basis for
a circulating system does has a special historical appeal to me: this
is the first known meantone (1558) to be described in precise
mathematical terms. Thus the above temperament recipe is an invitation
to a meeting between the old and the new, with the "seasoning" of
nanotemperament having two especially interesting consequences.
---------------------------------------
3. Optimizing the smallest minor thirds
---------------------------------------
In a temperament extraordinaire, one of the primary goals is to obtain
some small minor and large major thirds at or close to the septimal
ratios of 7:6 and 9:7, or about 267 and 435 cents; these will be the
smallest minor and largest major thirds of the tuning, generated
respectively by a chain of three or four wide fifths.
To see how my inadvertant nanotemperament scheme for the remote
portion of the circle served to promote this quest, let us consider
the relevant region of the tuning recipe:
C#/Db G#/Ab D#/Eb A#/Bb F
+180 +216 +216 +180
Since a minor third is generated from a chain of three fourths up
(F-Bb-Eb-Ab) or three fifths down, we can read this diagram from right
to left in order to locate the two minor thirds generated from three
wide fifths (or narrow fourths): F-Ab and Bb-Db.
Having the two more heavily tempered fifths at 3/10 Pythagorean comma
or 216 TU placed together in the central portion of this wide-fifth
region, with the two fifths at 1/4 Pythagorean comma or 180 TU at the
borders of the region, ensures that any minor third formed from three
wide fifths will get both of the 216 TU fifths, together with one
"border" fifth at 180 TU. This adds up to 612 TU of temperament in the
direction of 7:6.
Thus here is the situation for F-Ab:
F-Ab +612 TU
|----------------------------|
C#/Db G#/Ab D#/Eb A#/Bb F
+180 +216 +216 +180
and likewise for Bb-Db:
Bb-Db +612 TU
|------------------------------|
C#/Db G#/Ab D#/Eb A#/Bb F
+180 +216 +216 +180
How close to 7:6 are these small minor thirds? A minor third from a
chain of four pure 3:2 fifths would have a Pythagorean size of 32:27
or 294.135 cents. To obtain a just 7:6 third (266.871 cents), we must
do a full septimal comma (64:63) of tempering in the wide-fifth
direction, 27.264 cents or about 837 TU (almost precisely 836.75 TU).
Here we have done 612 TU of tempering for each of our smallest minor
thirds, leaving them about 225 TU wide of a just 7:6 -- or 7.323
cents. These thirds have a size of about 274.194 cents.
In the theoretical model for a 2/7-comma temperament extraordinaire,
these same thirds would have a size of 274.862 cents; so the necessity
of nanotemperament, along with the quirk of my placing those two wide
fifths at 216 TU together, has resulted in "optimizing" these
approximations of 7:6.
------------------------------------------
4. Outlying meantone thirds and E Phrygian
------------------------------------------
A temperament extraordinaire is meant for playing in modal styles of
music: typically Renaissance and Manneristic styles premised on
meantone in the nearer portion of the circle; and medieval or
neomedieval styles in the remote part of the circle premised on
Pythagorean intonation and its accentuated modern variations and
offshoots.
For music in Renaissance and Manneristic styles, having restful major
thirds quite close to 5:4 is an important consideration. This is
obviously no problem in the F-C# region of the tuning, identical to
Zarlino's regular 2/7-comma temperament -- apart from small and mostly
inconsequential variations on synthesizer due to nanotemperament. The
most "consequential" variation is that the fifths G-D and B-F# are
narrow by a tad more than 7 cents, rather than the 6.145 cents of
Zarlino's 2/7-comma. In effect, they are approximate 1/3-comma fifths:
tolerable, but not necessarily ideal.
Of more concern, from the perspective of major third quality, is the
"outlying meantone" region occupied by the thirds Bb-D and E-G#,
formed from three narrow fifths plus one wide fifth. In a theoretical
model of a 2/7-comma temperament extraordinaire, these thirds would be
at 395.810 cents, or 9.497 cents wide of 5:4. This is comparable to
the regular major thirds of 1/7-comma meantone (395.531 cents), and
also to the smallest and mildest major thirds of Werckmeister V and
some Neidhardt well-temperaments, for example, at 1/2 Pythagorean
comma smaller than the Pythagorean 81:64 (407.820 cents), or 396.090
cents.
Granted that using these considerably compromised major thirds in
place of their regular meantone counterparts is less than ideal, we
might wish, at least, to keep these "outlying meantone" thirds Bb-D
and E-G# as close to 5:4 as reasonably possible. This can be
especially desirable for E-G#, routinely used in closing sonorities in
untransposed E Phrygian, a common and very beautiful modality.
Here nanotemperament can contribute a small but helpful nudge in the
right direction. Let us focus on the nearer of meantone portion of the
tuning recipe, plus the two wide fifths Bb-F and C#-G# that border it.
Bb F C G D A E B F# C# G#
+180 -180 -180 -216 -180 -180 -180 -216 -180 +180
The two outlying meantone major thirds Bb-D and E-G# each have a
generating chain of four fifths including one fifth narrow by 216 TU,
two narrow by 180 TU, and one wide by 180 TU. The wide fifth, in
effect, "cancels out" the narrow tempering done by one of the 180 TU
fifths. This leaves a narrow tempering of 216 TU plus 180 TU, or a
total of 396 TU.
A chain of four pure 3:2 fifths would produce a Pythagorean major
third at 81:64; to obtain a pure 5:4 (386.314 cents), we must do a
full syntonic comma (81:80, 21.506 cents) or 660 TU of narrow
tempering. Here we have done 396 TU, or 3/5 of that comma, leaving
Bb-D and E-G# wide of 5:4 by 2/5 comma, or about 8.603 cents -- a size
of about 394.916 cents.
This is almost a cent closer to 5:4 than the theoretically expected
value of 395.810 cents, and curiously comparable to the smallest
minor thirds in the Prelleur temperament at about 394.669 cents. It is
still hardly an ideal situation, but a viable compromise slightly
improved.
Interestingly, this modestly more pleasant result with Bb-D and E-G#
owes itself in part to the same cause as the closer approach to 7:6 of
the small minor thirds F-Ab and Bb-Db: the arrangement of the four
wide fifths.
Arranging them with the two fifths at +180 TU, Bb-F and C#-G#, both
placed on the borders of the meantone region, as shown in the last
diagram, means that Bb-D and E-G# will each have in their generating
chains a wide fifth cancelling out only 180 TU rather than 216 TU of
the desired narrow temperament provided by the other three fifths.
Instead, the two more heavily tempered wide fifths G#-D#/Eb and Eb-Bb
are concentrated at the center of their region, as discussed in
Section 3, where rather than undesirably moving outlying meantone
major thirds further from 5:4, they can agreeably draw our smallest
minor thirds nearer to 7:6.
-----------------------------------
5. Conclusion, or postlude for Brad
-----------------------------------
Each tuning form, and musical style, may have its own constraints and
preferences. Writing this essay has been an opportunity to reflect on
some of the historical contrasts and playful paradoxes that can arise
when, as Vicentino proposed in his famous title, "ancient music" is
"reduced" or "adapted" to "modern practice."
I have devoted considerable space to the quest for 7:6 and 9:7 thirds
in a modern circulating temperament, because it is for me a high
musical priority -- but by no means necessarily a priority for those
of the meantone era, with interesting exceptions (notably Huygens).
Indeed, as Paul Poletti recently noted, Michael Praetorius reported a
name that early 17th-century musicians had given to the meantone
augmented second F-G#: "the wolf," a term now especially associated
with the diminished sixth or augmented third (e.g. G#-Eb or Eb-G#) in
a regular meantone tempered by about 1/6-comma or more.
Since Praetorius specifically favored 1/4-comma meantone with pure 5:4
major thirds -- the "Praetorian" temperament to later writers such as
Werckmeister -- we know that F-G# was very close to a just 7:6. Yet he
very clearly describes it as a "false minor third" -- an obstacle to
free harmonic navigation encountered in a usual 12-note temperament,
rather than an adornment, as Huygens would declare it in 1691.
It is thus a somewhat humorous modern predicament to be debating how
much to compromise both the narrow and wide fifths of a temperament
extraordinaire in order to "optimize for 7:6" -- that is, in terms
like those of Praetorius, to keep the "wolves" at F-G# and Bb-C# as
"wolfish" as possible while getting the fifths to circulate.
Moving ahead to the era of Bach and well-temperaments which you have
studied and explored so intimately, Brad, I also reflect on the
possible distinctions between modal and tonal approaches to the
question of the major third E-G#.
In a 16th-century modal style, where it is customary often to have
closing sonorities including a major third above the modal final,
obtained by inflection if necessary, E-G# is basic to E Phrygian, and
is one of my first criteria for evaluating any 12-note circulating
system. More generally, I would like each of the untransposed modal
finals (C, D, E, F, G, A) to have a major third within 9-10 cents of a
pure 5:4; and likewise Bb-D, which may occur often in various modes.
A temperament extraordinaire can meet this goal with fewer compromises
than tonal 12-note well-temperaments, because an equally important
goal is to obtain major thirds in the more remote portion of the
circle at sizes such as 421 cents or 434 cents. These are "excellent
neomedieval thirds" -- a rather different description than might be
applied in a tonal context around 1706 or 1722!
Thus each art form, contrapuntal or intonational, may have its own
peculiar rules. Brad, my warmest thanks to you as an artist and
scholar who has brought to my attention the noble ingenuity of the
temperament unit, and inspired me to seek creative by-ways for
applying it.
Most appreciatively,

Hi, Johnny, and thanks for a very friendly and pleasant dialogue. Maybe I should clarify that from my 21st-century perspective I'd regard WIV as _marginally_ circulating: 1/3-Pythagorean comma temperament of the fifths is a lot further than I'd like to go in a usual as opposed to "xentonal" style (a la Sethares). However, there's a much more basic reason I shouldn't overlook why WIV is _not_ circulating in a tonal context, nor in a 16th-century modal one: those thirds at 416 cents, and very possibly also those at 278 or 286 cents from a period perspective. My gut reaction is to run up and embrace those thirds as old friends! -- but _not_ evidently the general period view. Here WIII has tonal circulation; WIV doesn't. By the way, so that people can compare notes and versions, here's Scala's version of WIV in an octave of C-C: ! werck4.scl ! Andreas Werckmeister's temperament IV 12 ! 82.40600 196.09000 32/27 392.18000 4/3 1024/729 694.13500 784.36100 890.22500 1003.91000 4096/2187 2/1 > While I await a possible correction from Paul on WIV in C major, I > believe the historical situation for Werckmeister, who inherited > his positions using what he now call WIV, but which he credited to > Trost and his unnamed late cousin.

Here you make a _critical_ point: what someone like Vicentino, Werckmeister, or whoever writes _does_ tell us a lot about their viewpoint, and should be duly noted! Thus Schlick clearly wanted his poodle (or Lehmanian "prairie dog"?) at Ab-Eb to be used, because that's the whole point of the compromise with Ab/G#. The idea is to have Ab-C-Eb usable as a sustained sonority, as he does in his organ composition, with Ab-C maybe similar to 12-EDO, while still being able to use E-G# at around Pythagorean for ornamented cadences to A. An allergy to Ab-Eb would defeat that purpose. So it appears that Schlick is a "poodle-friendly" tuning. However, I seem to remember reading about someone around 1600 suggesting that 3:2 is "as wide as bearable," or the like, for a fifth -- which _would_ mean the kind of poodle allergy we're discussing. > It may be one of the most amazing challenges, the ability to get > into someoneâs head.

Please let me agree that while period literature, like any attempt to verbalize about music and musical taste, is necessarily incomplete, it is not unuseful. Thus reading Praetorius and Denis will at least alert me to the fact that they considered meantone F-G# a "wolf" or "false minor third" rather than "a beautiful and near-pure 7:6." Thanks to Paul Poletti for reminding me that Praetorius discussed the use of the term "wolf" _specifically_ to mean this third. In the early 14th-century Italy of Marchettus, 7:6 or so _may have_ been a favored tuning of a cadential minor third contracting to a unison (e.g. C#-E resolving to D), but we can't be sure. Christopher Page concludes that it should often be considerably smaller than Pythagorean, but leaves the details to the singers.

This is very true, and can affect my reactions both to the intervals themselves, and to seeing their sizes in cents: numbers like 274, 287, 416, or 427 cents make me feel a certain affection for a tuning. Of course, I still know that these sizes should not be taken as freely interchangeable with meantone thirds <grin> -- although sometimes I try curious things anyway. It's a bit like the question of parallel fifths, routine in a 13th-century style, but generally excluded in a 16th-century style (apart from relaxed styles like certain dance settings and the villanella). By the way, I recall some years ago playing in a usual 14th-century Pythagorean (Eb-G#) and hearing a diminished fourth (384 cents) as indeed something of a "wolf." Acoustically, to borrow from Gertrude Stein, it may be true that "a 5:4 is a 5:4 is a 5:4," and likewise "a 7:6 is a 7:6 is a 7:6." In varying musical contexts, however, they can indeed sound different, fitting or otherwise. > Your later comments: "What I've decided is that making new music > should be my first priority, and offering some curious > verbalizations about what I'm up to, however imperfect and > incomplete, a good next priority" make total sense as regards your > intervallic reactions. This is a direction in which George Secor encouraged me during our very fruitful dialogue of 2001-2002 concerning his 17-tone well-temperament: seeking out to compose and explore an "alternative history" where the music would, he predicted, likely sound less and less like anything historically familiar. Of course, there's a rich spectrum of degrees from something "musicologically correct" for a given period to something strikingly xentonal or the like. Most appreciatively, Margo

Mixing fractions with cents! Man, just stick to the one or the other. Or do it all in ratios to 13 decimals, which is how I do my calculations. It gives you the advantage of fairly simple numbers for consonances (like 1,5 or 1,25) AND the consistency of units, which is generally regarded as a desirable thing. Plus it assures a maximum of accuracy and freedom from rounding errors. I see no advantage to using 1024/729 for f#, especially as it returns a value which is INCORRECT by almost 1 cent (0,977 cents to be more exact). Even reducing the ratio to only 6 decimal places (the same number of digits), 1,405457, the answer is far closer to the real theoretical value than that returned by this fraction. It's precisely the avoidance of this sort of error which causes real scientists to avoid mixing units. It's also the desire to avoid this kind of error that caused me long ago to reject all precalculated values and sit down and do the numbers myself, using the original sources. It's not so difficult, now that we have XL to do the number crunching for us. I use but one ratio for any given tempered fifth, and I test all of my temperaments for cumulative error and except nothing less than a very long train of zeros after the 2 after going around the circle of fifths. Not that I think it is important audibly, it just keeps you from starting down that slippery slope which leads to really wanky values like Johnny gave us. Ciao, P

Turns out I grabbed the wrong ratio from the wrong column in my master spreadsheet that allows me to manipulate values between an original and a slightly altered version of a temperament.

From: [email protected] (2007-10-28) Subject: Re: Wolves, poodles, goats, and styles Thank you, Margo, for reevaluating WIV from a different angle. And thank you for posting the mix of ratio and cents that you retrieved from Scala. The more information given, in all its guises, the better for a full evaluation, not only of the truth, but of different errors that are circulating. This List is for exploration, not necessarily for circulation. The more I think of the literature, the less I think is its percentage of full revelation of a historical musical practice. Besides the translation problems, and Werckmeister's translations are more difficult in the regularly recurring Latin than in the German, few tend to read what gets published. Please correct me if warranted, but few read Grammateus in his life time. Werckmeister, on the other hand, was ingenious in getting his work published and distributed throughout the German speaking world. It would be interesting to list important writings on tuning according to the category of dissemination. More important, for most, is the value place on the writings due to influence on later generations, and here we might place Kirnberger. Still, more important, much of musical action is not written about in books, especially by musicians. Note how few microtonal musicians are on this List. If you are unfamiliar with them, I can make a list for you later. Musicians, as should be commonly understood, regularly deal with the ineffable. Simply, they are not verbal. In this I am a notable exception. (At Columbia I was called by my advisor "a talking chimpanzee." >Thus Schlick clearly wanted his poodle (or Lehmanian "prairie dog"?) at Ab-Eb to be used, because that's the whole point of the compromise with Ab/G#. The idea is to have Ab-C-Eb usable as a sustained sonority, as he does in his organ composition, with Ab-C maybe similar to 12-EDO, while still being able to use E-G# at around Pythagorean for ornamented cadences to A. An allergy to Ab-Eb would defeat that purpose. So it appears that Schlick is a "poodle-friendly" tuning. Margo, because I have been so busy teaching this year, I had to pause on my Bach's Tuning work, sometimes finding myself confused as to where I got something. I had a source on Schlick where he wrote of what to avoid and yearn to find it again. Most dramatic in my college experiences was taking a Renaissance music graduate course with Prof. Lippman at Columbia University. Lippman was known for his book on ancient Greek tuning. When I appeared in his class, as an ethnomusicology grad student on fellowship, I was asked to leave the class. It had been determined that as an ethnomusicologist, there would be no reason for me to be there. Intervals were to written on a blackboard in ratios. When I brought in a Korg tuner to play the intervals, they shuddered and shrank. Now that I have the WIV numbers correctly crunched thanks in part to my good friend at NYU, I see that there are 2 dogs at 710. Dogs are clearly, for me and maybe for others in earlier times, simply "over the top." :) Margo: However, I seem to remember reading about someone around 1600 suggesting that 3:2 is "as wide as bearable," or the like, for a fifth -- which _would_ mean the kind of poodle allergy we're discussing. Johnny: Exactly my view expressed. > It may be one of the most amazing challenges, the ability to get > into someoneâs head. Actors do it all the time.

Please let me agree that while period literature, like any attempt to verbalize about music and musical taste, is necessarily incomplete, it is not unuseful. Thus reading Praetorius and Denis will at least alert me to the fact that they considered meantone F-G# a "wolf" or "false minor third" rather than "a beautiful and near-pure 7:6." Thanks to Paul Poletti for reminding me that Praetorius discussed the use of the term "wolf" _specifically_ to mean this third. Johnny: On a lighter point, we might substitute "indicate" for "mean" in the previous sentence. :) Margo: By the way, I recall some years ago playing in a usual 14th-century Pythagorean (Eb-G#) and hearing a diminished fourth (384 cents) as indeed something of a "wolf." Acoustically, to borrow from Gertrude Stein, it may be true that "a 5:4 is a 5:4 is a 5:4," and likewise "a 7:6 is a 7:6 is a 7:6." In varying musical contexts, however, they can indeed sound different, fitting or otherwise. Johnny: Again relating to that Columbia class, I wanted to set the terminology that a ditone was not a major third (to no avail). Certainly they come from different perspectives. They were used at different times, with ditone being the earlier term. About the 7, there is Tartini (by repute used in his playing...though maybe you know of some specific usage of 7-limit intervals), and Kirnberger (who notated with the letter i in his Flute Sonata for a 7/4 (969) cent interval). Margo: This is a direction in which George Secor encouraged me during our very fruitful dialogue of 2001-2002 concerning his 17-tone well-temperament: seeking out to compose and explore an "alternative history" where the music would, he predicted, likely sound less and less like anything historically familiar. Of course, there's a rich spectrum of degrees from something "musicologically correct" for a given period to something strikingly xentonal or the like. Most appreciatively, Margo Johnny: La Monte Young had a similar idea, that one must compose music that sounded like it had a great history behind it, ala Bach. Pioneers don't necessary last forever in contradistinction. You certainly have it under control. Happy composing! joyfully, Johnny ************************************** See what's new at http://www.aol.com
From: Margo Schulter (2007-10-29) Subject: Werckmeister IV variant: 1/3-SC fifths? Hello, everyone, and thanks to Tom, Johnny, Paul, and others for prompting me to an idea concerning one possible variant on Werckmeister IV. First, based on Werckmeister V, one might guess that Werckmeister regards wide fifths about as playable in themselves as narrow fifths sharing the same degree of impurity. Secondly, in Werckmeister IV, the fifths tempered by 1/3 comma are not restricted to remote portions of the circle: rather they occur in such prominent positions as C-G, D-A, and E-B. Looking at that beautiful fascimile of Werckmeister's 1681 organ tempering diagram, Paul (many thanks!), it occurred to me that if the "comma" may be either Pythagorean or syntonic, with the schisma regarded as not so important, then why not 1/3-syntonic comma tempering for the narrow and wide fifths alike? Here are two Scala files for this variant reading, the first in usual Scala style with just intervals indicated as interval ratios; and the second, as you've suggested, Paul, with all ratios given in cents. As well said by Thomas Morley (1597) on such points of preference: There be more ways to the wood than one. ! werckmeisterIV_variant.scl ! Werckmeister IV with 1/3 syntonic comma temperings 12 ! 85.00995 196.74124 32/27 393.48248 4/3 45/32 694.78624 785.01123 891.52748 1003.25876 15/8 2/1 ! WerckmeisterIV_variant_c.scl !

The 1/3-comma variation seems to fit this model -- at least if, like Costeley (1570) and Salinas (1577), we are ready to accept fifths tempered by this great a quantity, as in a regular 1/3-comma meantone or 19-EDO. Zarlino (1571) found 1/3-comma temperament "languid," in contrast to either 1/4-comma or his own 2/7-comma -- but not, as I recall, outright unacceptable. If one can bear with these fifths, then one advantage for usual diatonic transpositions (modal, or by this epoch tonal also) is that each of the seven major thirds formed from two _musica recta_ notes (the diatonic steps plus Bb) will be uniformly at 1/6-comma meantone quality -- except for E-G#, which will actually be a schisma closer to 5:4 because of the "schisma fifth" in its chain at C#-G#. At Eb-G we have a fifth at about 401 cents, considerably less than ideal but still tenable, in modes like G Dorian or F Lydian or Ionian, a compromise possibly rather like Schlick's (1511) with Ab-C. The schisma adjustment of C#-G# in this 1/3-syntonic comma version may offer a small but notable advantage in pieces calling for B-D# as a usual major third: this third is a schisma smaller than Pythagorean, or around 406 cents, the size which Easley Blackwood has suggested may mark the limit for a stable major triad in a tonal style. In contrast, C#-F, F#-Bb, and G#-C remain appreciably wider than Pythagorean, at about 413-415 cents, also the evident upper limit for major thirds or diminished fourths in Schlick's temperament and some versions of the temperament ordinaire in favor at the time of Werckmeister's treatise of 1681. Brad might note that the augmented fifth C-G# gives a nice approximation to a just 11:7, by the way -- this is something that I look for, also. These three diminished fourths would nicely fit their role as "special effects" intervals in meantone, and might sometimes be used as "marginally interchangeable" with more usual major thirds, as Mark Lindley describes in French keyboard music of Couperin. George Secor's modern temperament ordinaire also explores this territory. However, if we take the main focus of Werckmeister IV to be a conventional diatonic style, then the 1/3-syntonic-comma variant does seem an attractive solution if one can accept this much temperament of the fifths, a la Costeley or Salinas. Please let me conclude, Tom, by thanking you for your at once diligent and creative insight that Werckmeister's Septenarius temperament (Werckmeister VI) might better fit his own declared musical goals and standards if the monochord value printed as "176" were read as "175." I looked at your proposal, and quickly saw how much sense it made! That gave me the idea of considering whether, if either a Pythagorean or a syntonic comma is a possible reading of Werckmeister's diagrams, an interpretation of the "comma" in Werckmeister IV as syntonic might not likewise promote his musical purposes.

I'll repeat my recommendation that TUs not be used, since they lack a precise definition. Anything you can use TUs for you can also use flus, for; with exactly 46032 flus to an octave, 900 flues to a Pythagorean comma, and 825 to a Didymus comma. Of course, you can define TUs so that the Pythagorean comma is *exactly* 720 TU, but now larger intervals don't come out evenly. With flus you know precisely what to call any 5-limit interval in flu terms.

If you absolutely must use TUs, I suggest defining them so that the octave is *exactly* 36825.6 TU, with the fifth taken as 21541.6 TU and the major third taken as 11855.2 TU.

Since the "definition" of TU gives integer values for the two commas, anything which is a product of these comes out evenly, but that excludes most intervals.

And they work perfectly for the purpose they were designed for. Brombaugh chose 720 *because* 720, 660, and the difference 60 are all so easily divisible by 2, 3, 4, 5, and 6...which are the main types of comma splits in historical temperaments (having nothing to do with any computers or synthesizers, or even for that matter with theoretical speculations either). He wanted a simple system with which he could explain on paper -- with no calculators or computers -- the various distributions of those two main commas, and the schisma. It's the easy stuff one can draw onto a napkin at dinner, or mentally in the shower or on a bike ride, dealing with simple arithmetic. When everything works out so neatly as integers, it's plenty clear down to (and way beyond) the level that any human being can hear any of these intervals. It's a system for measuring comma distributions, and it's logarithmic, so the everyday operations get reduced to addition/substraction instead of multiplication/division. It's not designed for use beyond the width of (say) 2000 or 3000 TU. It scarcely has application beyond 720, frankly, unless the topic of interest is a diesis. If anybody wants to do more precise yet less practical things, they can go make up their own unit that is additionally divisible by 7 and 11 and 13 and 17 if they care to. Or define the whole octave as "a bazillion" logarithmic units and then start chopping it up, with or without any round-off errors down below the threshold of pitch discrimination of any living being. The main point is: Brombaugh wanted something finer-toothed and more comma-centered than cents are, for basic explanations on paper. And he succeeded. Brad Lehman

Mental processing of tuning concepts in the shower *is* theoretical speculation. My bad. Carry on. The rest of my point remains, for what it's worth. If we're trying to do 1/7 syntonic comma on a non-electric instrument, 94 TU is close enough, and then some. How big is the major 3rd in regular 1/7 syntonic comma? Tally up four 94s to 376. Divide by 660. We're about 57% of a syntonic comma sharp, above a pure 5:4 major 3rd. See, that's all we *really* need to know in practice. Pencil and paper with arithmetic any 12-year-old should know. Brad Lehman

What, nobody has kicked me in the head yet for the error in that illustration, from my haste at typing it? OK, I'll fill in the missing step myself. Tally up four 94s to 376. That's the amount flat from a Pythagorean ditone. To get the amount sharp from a pure 5:4, we have to subtract from 660...getting 284. Then divide *that* by 660 to see what percent of comma we're sharp, and it's 43%. Brad Lehman

I do know what they are used for, but I think a system to analyze 5-limit intervals which can only deal with a small subset is intelletual crippleware. > Brombaugh chose 720 *because* 720, 660, and the difference 60 are all > so easily divisible by 2, 3, 4, 5, and 6...which are the main types > of comma splits in historical temperaments (having nothing to do with > any computers or synthesizers, or even for that matter with > theoretical speculations either). Then he could at least have made a real definition, by for instance setting the apotome to 3488.8 TU. As it is, YUs are not defined except on a small subset of 5-limit intervals. Hell of a way to run a railroad. > When everything works out so neatly as integers, it's plenty clear > down to (and way beyond) the level that any human being can hear any > of these intervals. And using flus, or defining the apotome as 3488.8 TUs, doesn't do this because...?

Depending on how you set up the calculation, *even without using approximations*, you come up with different answers. The size of the major third in 1/7-comma meantone using the intellectual crippleware you advocate is undefined. Do it my way, and it is 15172 4/7 flus, which is 12138 2/35 TUs. The major third is 14819 flus, which is 11855.2 TUs. The difference is 355 2/7, which is *exactly* 3/7 of a syntonic comma of 825 flus. You get the same answer if you use my suggestion for defining TYs for all 5-limit intervals. No vagaries about "about 57%" need apply; which anyway whould be about 43%. And while there is a tiny imprecision from ignoring the atom, the conclusion that it is exactly 3/7 of a syntonic comma sharp is correct.

Anybody should get the *exactly* 3/7 of a syntonic comma answer, without having to calculate down to any of these units, or pick any amount of decimal round-off. We've taken 1/7 comma off each of four 5ths, such as C-G-D-A-E to build a C-E of some size. There are therefore 3/7 of that comma remaining. The major 3rd is therefore 3/7 of a syntonic comma sharp from 5:4. Exactly. Coming down from a Pythagorean ditone toward a pure 5:4 major 3rd, we've succeeded in knocking off 4/7 of the error, the syntonic comma. The "intellectual crippleware" you're complaining about (the TU that you're rubbishing) is not designed to measure the entire size of the interval, but only the distance of the error from pure 5:4. There is nothing "crippling" about this. It only answers a different type of question than you would pose to it. Listening to a real organ or a real harpsichord, the normal listener is not going to give a flying fig how big the major 3rd is in absolute size, measured in any numerical units from bottom to top, either in some logarithmic units or as numerical frequencies per unit of time. Rather, the perception (well, at least for me!) is: "about how much" is the interval wavering, being not quite on a pure integer ratio spot? It's some amount sharp. How much? A little less than half a comma, or 3/7, or about 43%. Or a smidge under size 5 on the 11-unit metric from Sorge et al, where 11 is a Pythagorean ditone, and a 12et major 3rd works out to exactly 7. How big is the entire major 3rd on that 11-unit metric? It's not designed to answer that question. It's designed, rather, to tell us how many 1/11ths of a syntonic comma we're off from pure in a given major 3rd. All the TU system does is multiply this by 60, and it answers similar questions. There exists a scale of Scoville Units to measure the pungency of chili peppers. http://www.chemsoc.org/exemplarchem/entries/mbellringer/scoville.htm But when you go to a restaurant and peruse the menu, does it give you any numerical measurements in Scoville units? No, you get something like Mild, Medium, Spicy, and maybe a fourth option, and you pick one, and then the chef tries to give you something accordingly to the taste you said you wanted. The chef probably doesn't even know or care what absolute number of Scoville units his dish would register, nor does the customer; only that it tastes enjoyable and as ordered. Is the Mild-Medium-Spicy scale "intellectual crippleware", or does it really help the customer get what he wants to eat? Let's ask the flu system some question it's not designed to answer. How much is 1/3 of a major 3rd, in flus? Well, let's see. The entire major 3rd, presumably a pure 5:4, is (according to you) 14819 flus. And it's not evenly divisible by 3. It comes out to a repeating decimal and can never be rounded off accurately! Nor is 14819 divisible by 2, 3, or 5. It *is* divisible by 7 and 2117, so maybe the flu is designed to hack major 3rds into seven equal pieces? What kind of system assigns a big unit that is not divisible by 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 but *only* by 7? Well, I guess it's just not designed to answer such questions expecting the answer of an integer. Does that make it "intellectual crippleware", or is it merely a tool being misapplied to a wrong task? How big is a major 3rd in Fahrenheit? Brad Lehman
From: Brad Lehman (2007-10-30) Subject: some 2/7 comma experiments on harpsichord Spurred by Margo's recent postings, I've tried some experimentation with 2/7 syntonic comma on harpsichord. Here are some preliminary comments from that. These are all from working it by ear at the instrument, not calculating anything. I set up regular 2/7 all the way around from Eb up to G#. The major 3rds are a little bit narrow, the minor 3rds (6:5) scarcely wide. The F# to Bb, B to Eb, C# to F, and G# to C work out to hit almost on a 9:7, and the F to G#, Bb to C#, Eb to F# are almost on 7:6. With this installed I played through a bunch of random pages of medieval and Renaissance music, mostly vocal, from the _Historical Anthology of Music_ (HAM). Margo's point, as I recall, is to set up something suitable for accompanying this type of repertoire. Then I tried her recommendation of converting this to _temperament extraordinaire_ (her nomenclature, not mine; I'd already co-opted the phrase "extraordinary temperament" to mean something different, a couple of years ago...). That is: stretch F-Bb-Eb wide each, and F#-C#-G# wide each, so it eradicates the wolf G#-Eb and reduces it to four other lesser canines, all the same as one another. In practice at harpsichord this is simply a process of cranking the Bb and Eb downward in turn, and the C# and G# upward in turn, until we have similar 5ths F#-C#-G#-D#-A#-E#. They're all a little bit rougher than the 2/7 comma 5ths, and of course they're rough in the opposite direction, but given that all these 5ths/4th are growly anyway they don't sound too bad in context...playing them as open 5ths/4ths, without any 3rds (whether major or minor) in them. But, does it work? I played some more from HAM, some of the same compositions and some others randomly. To the extent that the notes Bb, Eb, G#, and C# came up, which was rarely, they always stood out to me as not fitting their context when played in major or minor 3rds. Neither fish nor fowl. Especially in the case of Bb, the most frequent of these four notes, it seemed to me there's too much difference in character between the Bb major triad and the F major triad, and between the A-Bb semitone vs the E-F semitone. The Bb-D is scarcely wide as a major 3rd, and pleasant enough, but it doesn't have that tight center of gravity like the major 3rds on the naturals. Similarly, A-C# is only a little bit wide but it's lost its gravity. And Eb-G and E-G# are watered down even more, each. They're still smaller than Pythagorean ditones and they're pleasant enough, in isolation, but they don't seem to fit their context. Worse yet: we haven't really gained any usable B-D#, F#-A#, Ab-C, or Db-F. They were kind of OK and attractive in their own way (while exotic) when they were hitting nearly 9:7, tuned regularly. But now, having these modified 5ths, these misspelled major 3rds are in a no-man's-land. They just sound like "wrong notes" giving nothing for my ear to grab onto, or to take me past the wincing. I kept itching to put them back down (sharps) and up (flats) where they belong. And in doing so, I found that I was presented with several viable places to put each of those stinkers Bb, Eb, C#, and G#. Well, first, the Bb almost had to go back to its regular 2/7 position so it's not sticking out as mentioned above. Having done that, there are four or five arguably decent places to put the others, all pretty close to one another when turning the tuning pin and sliding through all possibilities. C#: back to its regular 2/7 comma place from F#, or tune it as a pure 5:4 from A-C#, or tune it as pure 7:6 with Bb, or tune it as pure 9:7 from F. Or, simply as a pure 3:2 from F#. All five of these spots are arguably good for C#. Following Margo's lead I favored the two septimal spots. Why hit only near a 7:6 or a 9:7 when you can hit directly on one of them? It makes the minor triads, diminished triads, and tritones lock in that way, too. G# similarly has four or five spots: its 2/7 comma tempering from C# (before we moved C#), or as 5:4, 7:6, 9:7, or 3:2 from its neighbors. And Eb similarly has those options with respect to Bb, B, F#, and G. All of this writes off the G#-Eb wolf as a loss...but it's not going to come up in this medieval and Renaissance music anyway. And by going back to regular 2/7, or nearly so (choosing septimal placements on C#, G#, and Eb), we've got a fantastic set of eleven minor triads, eight tightly attractive major triads, three septimal major triads, and all the other related emoluments. The 5ths F#-C#-G# and Eb-Bb work out decently (for context) no matter what we do, given that the 2/7 comma 5ths on the naturals are already rough. If the point is to accompany medieval or Renaissance [vocal] music, regular 2/7 works better (at least for me) than the 5th-stretching _extraordinaire_ step does. If the point was to get those septimal resonances going, why move off them by widening the 5ths? I could change my mind tomorrow, but that's how I hear it today. And all of this might work better (or worse?) on organ as opposed to harpsichord. On harpsichord, at least, the septimal intervals are clear and pungent. And if the notes D#, A#, Ab, and Db aren't going to come up in the music anyway...why not just stick with regular 1/4 instead of 2/7? It's sort of a trade-off here between the major 3rds and minor 3rds. But if we wanted pure minor 3rds, why not go all the way to 1/3 comma then? 2/7 goes down between these, giving the strengths of both...and because those 3rds aren't pure, they're (arguably) more attractive just by virtue of being livelier, not sitting there dead-on. Every listener might of course have a different opinion about that. Brad Lehman

Every listener > might of course have a different opinion about that. 2/7-comma meantone is in fact the variety of meantone which both minimizes and equalizes the error for all of the main ratio-of-5 intervals simultaneously: ratios 5:4 & 8:5, and 6:5 & 5:3. You can see this in the last graphic at the bottom of my webpage: http://tonalsoft.com/enc/number/2-7cmt.aspx In that graphic, the blue plots represent the temperament of these four 5-limit ratios. These graphic comes from a javascript applet i have on another page: http://tonalsoft.com/enc/m/meantone-error.aspx If you mouse over the meantone names on the left side of that graphic, you can see the plots of each meantone move as your mouse points over the different names. I could have made these graphs much better by including labels showing the ratios ... so i'll give them here: * the red plot below the thick zero-error line is the amount of error of the 3:2 ratio, and the red plot above that line is the error for 4:3, * the dark blue plots, from left to right, represent the error for ratios 8:5, 6:5, 5:3, and 5:4. * the yellow plots represent selected ratios-of-7 and the light blue plots represent selected ratios-of-11, as tabulated directly under the graphic. Note also that the fraction-of-a-comma error is exact for the ratios-of-3 and ratios-of-5, but only approximate for the ratios-of-7 and ratios-of-11. In case the reason for that is not obvious, it's because the syntonic-comma *is* a ratio-of-5. Keeping those labels in mind, you can see by simply following the movement of the various colors of the plots, that: * 1/3-comma meantone gives 6:5 & 5:3 with no error, and the same amount of error, namely 1/3-comma, for that meantone's approximation of the two pairs of ratios 5:4 & 8:5 and 3:2 & 4:3; * 1/4-comma meantone does something similar, but gives JI ratios for 5:4 & 8:5 (the other pair of ratios-of-5) with no error, and the same amount of error, 1/4-comma, for 6:5 & 5:3 and 3:2 & 4:3; * 2/7-comma meantone equalizes the amount of error for the two pairs of ratios-of-5: all four of them have 1/7-comma error, while the ratios-of-3 (3:2 & 4:3) have 2/7-comma error. Paul Erlich noted that it was perhaps the the new preference for composers to feature ratios-of-5 in their work during the Renaissance, along with this aspect of 2/7-comma meantone (that it provides the lowest aggregate error for the ratios-of-5), which may have led to its advocacy during that time. While vague descriptions of meantone began to appear about 50 years earlier, 2/7-comma was the earliest mathematically-described meantone to be advocated. It can also be seen from viewing the various different meantones on this graphic that, according to this particular error measurement: * 1/4-comma gives the lowest overall error for all 5-limit intervals (that is, including also the 3-limit 3:2 & 4:3); * 3/13-comma (and its close relative 136-edo) gives the lowest overall error for all of the 11-limit ratios i used in my evaluation. As it became more and more important for composers to once again emphasize the harmonic paradigm of ratios-of-3 in their music, the natural tendency would be a desire to reduce the error for those ratios as well (at the expense of the accuracy of the ratios-of-5), which would lead to a preference for 1/4-comma meantone, and eventually, to meantones with even less amount of tempering, such as 1/5-comma and 1/6-comma and, finally, 1/11-comma (which is essentially indistinguishable from 12-edo). -monz email: joemonz(AT)yahoo.com http://tonalsoft.com Tonescape microtonal music software

It cannot do this without further definitions. The problem is this:
TUs are defined by giving the value 660 to a syntonic comma and 720
to a diatonic comma. From this it follows that the atom, calculated
from 12*660-11*720, is set to zero. However, nothing follows for the
value of a pure 5:4, since both the syntonic and diatonic comma are
set equal to zero by 12-et. Consequently, all products are set equal
to zero also. It can only represent intervals which are in
the "kernel" of the 12-et map, and 5/4 is not in the kernel, being
four steps of 12-equal.
If we assume a regular mapping ("val") Let's ask the flu system some question it's not designed to answer.
> How much is 1/3 of a major 3rd, in flus?
You need to ask this in a tempering context because...? Flus multiply
TUs by 5/4, and so exchange a factor of 4 for a factor of 5. Since
divisibility by 2 is so easy, and by 5 not much harder, this isn't
actually a big difference. In any case, obviously TUs aren't doing
the job at all, whereas anything TUs can do, flus can do and with
about the same degree of ease.

That would indeed be a precise definition. But then it would be false that the syntonic comma was 660 TUs; it would acually be 660.0392862471599369... TUs, as you indicate above. And then, you would not be ignoring the atom; the atom is now .471434965919245629... TUs, which if the TU is our unit is not really negligable. I take the TU system to be one which assigns 720 to the P7ythagorean comma and 660 to the Didymus. It is therefore defined for all intervals which are products of these, which is precisely the kernel of 5-limit 12-equal.

Here I consider this kind of empirically fine-tuned solution as a creative side of things that must have often shaped the historical temperaments that are now all too easy to approach mainly as neat mathematical constructs. I'm honored to have played some role in this process, and would like to say so in a short post where your new variation, admirably suited to historical Renaissance music, can enjoy center stage. In a longer post, I've responded to your comments about the _temperament extraordinaire_ at some length, and mainly to clarify that this system is meant mainly for _new music_ which mixes or alternates Renaissance styles using meantone colors in the nearer portion of the circle with medieval or especially neomedieval styles using modes transposed to the remote portion of the circle with its large major and small minor thirds. This is a kind of 21st-century manneristic tuning, combining two very different styles of intonation in one 12-note circle, with many inevitable, striking, and hopefully artful distortions. However, your septimal refinement of a usual 2/7-comma has the great advantage for period performances of leaving the usual meantone structure intact while gently optimizing 7:6 and 9:7. It might be called "neo-classical" in the best sense: keeping the advantages of the original scheme while subtly nuancing it for the ears of the discerning. Please let me thank you for taking the time and effort for such a thoughtful musical exploration, and congratulate you on your choice variation! With many thanks, Margo

Hello, Tom.
Happily I find that the TU is a good tool to solve this problem, and
will try to explain my process for solving it in a reasonably
comprehensible way, I hope.
To start with, let's consider that in a regular 12-note meantone, F-G#
will be formed from a chain with one Wolf fifth plus two regular
meantone fifths. For example:
F - Bb - Eb - G#
regular regular Wolf
Now we know that the net tempering of those three fifths has to be
equal to the septimal comma or Comma of Archytas (thanks to George
Secor for the latter name!) at 64:63, 27.26 cents, or 836.75 TU.
More specifically, this net temperament of the fifths must be in
the wide direction.
Let's take that as an even 837 TU for most practical purposes. If we
use "t" for the temperament of the regular fifths (the unknown to be
found), and "w" for the impurity of the Wolf fifth in the wide
direction ("w" standing for either Wolf or wide), we have:
w - 2t = 837
Next, let us consider the relationship between t and w. If we take t
as the amount by which regular fifths are tempered narrow, and a
positive value for w to mean the amount by which the Wolf fifth is
wide of a pure 3:2, then we have:
w = 11t - 720
This means that we take the total amount of negative temperament done
by the 11 regular meantone fifths, and subtract 720 (the Pythagorean
comma) to find out the amount by which the Wolf exceeds 3:2, and so
can contribute toward a septimal size for an augmented second like
F-G#.
Now, substituting our second equation for the size of the Wolf fifth
into the first concerning the net temperament of F-G#, we have:
11t - 720 - 2t = 837
This simplifies to:
9t - 720 = 837
and further to:
9t = 1557
and thus:
t = 173
This seems intuitively a reasonable result, since we know that
1/4-comma at 165 TU comes very close, but with F-G# a bit larger than
a just 7:6. This is a regular fifth at about 696.32 cents, or 5.64
cents wide, as an approximation based on 837 TU for the septimal
comma.
It would be more accurate to do the same calculation with a value of
836.75 TU for this comma. Instead of dividing 1557 by 9, we divide
1556.75 by 9 -- otherwise, the process is the same. We get about
172.972 TU, at least according to my Orpie calculator program.
The result is a meantone fifth of about 696.319 cents, or 5.636 cents
narrow of 3:2. Scala shows the 7:6 minor third or augmented second
accurate to 0.001 cents.

Dear Brad, Thank you again for devoting this kind of creative energy to a tuning system in a very hands-on way, exploring its nuances and indeed customizing it to your own very experienced tastes. In my response, I'll try to keep to this spirit by avoiding too much mathematical complexity and focusing on the sound of the intervals and their intended musical effect. Your impressions are fascinating to read, and come from someone who can illuminate all kinds of practical angles that my experience simply doesn't cover. While it appears that our recipes for tuning the _extraordinaire_ may have varied a bit, as explained below, most of your comments are equally applicable to my recipe. They neatly highlight some aspects of the tuning, and questions about its purpose, which I'll try to address here, and ask for your feedback on how well I'm doing. I've decided to rewrite my original long response, because I realize that the biggest issue needing clarification here may be the _purpose_ of the tuning. As will appear below, it is a hybrid circulating system meant mainly for _new_ music often alternating between or juxtaposing Renaissance/Manneristic meantone styles in the nearer portion of the cycle with medieval or especially neomedieval styles using transposed modes focusing on the remote portion of the circle. Here's a piece I did in a mostly 16th-century style emphasizing the nearer portion of the circle, with a few septimal touches: <http://www.bestII.com/~mschulter/IntradaFLydian.mp3> Here are some neomedieval pieces and improvisations focusing on the remote portion of the circle: <http://www.bestII.com/~mschulter/MMMYear001.mp3> <http://www.bestII.com/~mschulter/InHoraObservationis.mp3> <http://www.bestII.com/~mschulter/OElsa.mp3> Following your admirable lead of giving first place to actual sound and musical experience, I'm offering this sample of how the _temperament extraordinaire_ sounds with music designed for or adapted to it. In some of what follows, I'll refer back to these pieces to illustrate some of your very well-taken points and explain why I find certain compromises acceptable or even attractive for my purposes -- but not necessarily for others! > I set up regular 2/7 all the way around from Eb up to G#.

Brad, you've hit on one of the attractions of 2/7-comma: if the idea is to optimize both 9:7 and 7:6, this is a "sweet spot." A small clarification: in 2/7-comma, the minor thirds are also "a little bit narrow" of 6:5, as you have noted the major ones are of 5:4. > With this installed I played through a bunch of random pages of > medieval and Renaissance music, mostly vocal, from the _Historical > Anthology of Music_ (HAM). Margo's point, as I recall, is to set up > something suitable for accompanying this type of repertoire. For Renaissance music, I would indeed say that a regular 2/7-comma (or 1/4-comma) is hard to outdo, in comparison to _any_ 12-note circulating scheme! For medieval music, I'd likewise recommend the usual period tuning of a regular Pythagorean -- or possibly, for a discreetly "modern" variation, something like Peppermint where all regular fifths are a tad more than 2 cents (66 TU) wide of 3:2. My circle, in comparison, can hardly be ideal if we are aiming consistently for either type of period sound. As compared with a regular meantone, some very important pure or near-pure thirds are compromised; as compared with Pythagorean or even a modern variant such as the gentle Peppermint, the fifths are impure by 6-7 cents! This will come out more in your remarks below and my responses. The purpose the _temperament extraordinaire_, rather, is primarily to accommodate new music which is free to transpose any mode to any step, or cadence on any of the 12 fifths, suiting the style to a given region of the circle -- now Renaissance meantone, now neomedieval, sometimes with striking transitional colors or "fringe effects." Actually I _do_ use this tuning for playing historical Renaissance pieces in the nearer portion of the circle (Bb-G#, with Eb calling for discretion as discussed below), and like the result -- but a regular meantone would, as you note, be more idiomatic and consistent both harmonically and melodically with a period ethos. > Then I tried her recommendation of converting this to _temperament > extraordinaire_ (her nomenclature, not mine; I'd already co-opted > the phrase "extraordinary temperament" to mean something different, > a couple of years ago...). Please let me join you in noting the difference between the French term _temperament extraordinaire_, which I've been using since 2003 <http://launch.groups.yahoo.com/group/tuning/message/43016> to describe a modified 1/4-comma or 2/7-comma meantone with eight narrow and four equally wide fifths; and "Bach's Extraordinary Temperament," the title of your articles of 2005. I've never thought of translating my French term literally into English, and your personal trademark now clearly stamped on the phrase "extraordinary temperament" is another reason not to do so. > That is: stretch F-Bb-Eb wide each, and F#-C#-G# wide each, so it > eradicates the wolf G#-Eb and reduces it to four other lesser > canines, all the same as one another.

Please let me clarify that my recipe for the _extraordinaire_ is a bit different in that only three notes are adjusted: Bb, Eb, and G#. The following diagram using our beloved TU may make this clearer: F C G D A E B F# C# G# D#/Eb A# F -189 -189 -189 -189 -189 -189 -189 -189 +198 +198 +198 +198 One aural recipe for use at the harpsichord might be to tune the eight fifths F-C# in a regular 2/7-comma, thus setting nine of the 12 notes. Then, _without changing any of these notes_, temper G#, D#/Eb, and Bb so that the near-9:7 major third or diminished fourth C#/Db-F already set is derived from a chain of four equally wide fifths. Specifically, in my recipe, C# is not adjusted, so that A-C# stays a regular meantone third and C#/Db-F stays at its near-9:7 size. This changes the details of the compromises involved, but not their basic nature, which you well describe. You make a very important point about the wide fifths: > They're all a little bit rougher than the 2/7 comma 5ths, and of > course they're rough in the opposite direction, but given that all > these 5ths/4th are growly anyway they don't sound too bad in > context...playing them as open 5ths/4ths, without any 3rds (whether > major or minor) in them. Thank you for this invaluable aural feedback, which for me is really a critical point: in a medieval or neomedieval styles with their remote modal transpositions, those wide fifths are indeed going continually to be used as stable consonances without any thirds, in this context definitely unstable intervals. > But, does it work?

Here I might be curious as to whether these were mainly medieval or Renaissance pieces from HAM, or some mixture. I'll focus here on a Renaissance style, since typically with medieval pieces I would make remote transpositions (e.g. D Dorian to Eb or Bb) that would bring other intervals and issues into play, some addressed below. So that people can hear some of the things you discuss in relation both to altered third sizes and melodic semitones in a Renaissance meantone kind of style, here's a link repeated for convenience to my _Intrada in F Lydian_, which prominently uses lots of the accidentals and intervals you mention. Apart from the matter of C#, which as I noted is not modified in my recipe, all of your comments apply: <http://www.bestII.com/~mschulter/IntradaFLydian.mp3> Thus while usual meantone thirds are at 383 cents, a tad narrow of 5:4 as you have said, Bb-D is around 396 cents, and Bb-D-F often occurs close to a near-pure sonority such as F-A-C or D-F#-A. While I might call this "a stimulating touch of modal color," it's definitely a compromise for a period sound where the uniformly pure or near-pure thirds of regular meantone are the norm. Also, the major third Eb-G, used here in the sixth sonority Eb-G-C, is actually at 408 cents a tad larger than Pythagorean; while I much like the color of this sonority and also C-Eb-G in a Renaissance as well as neomedieval context, it is in the former setting a dramatic departure from the smooth 5:4 sound again offered by a regular meantone. Your point about the different melodic sizes of A-Bb and E-F is also right on. While E-F is a regular 2/7-comma semitone at 121 cents, the altered A-Bb is about 108 cents (comparable to 1/5-1/6 comma), while Eb-D, featured in some cadences, is 96 cents. One can relish this variegation, or have more mixed feelings, but it is again a departure from a regular meantone where all these steps would be 121 cents. > The Bb-D is scarcely wide as a major 3rd, and pleasant enough, but > it doesn't have that tight center of gravity like the major 3rds on > the naturals. Certainly the different is there -- 384 vs. 396 cents. From a 21st-century perspective, I might argue that in a Renaissance kind of style with restful thirds, Bb is a less likely modal final than the naturals (other than B), and so, in a circulating system, can better afford some compromise. However, that argument is double-edged, as will appear shortly! In any event, for a period sound, regular meantone would, of course, leave Bb-D near-pure like the naturals. > Similarly, A-C# is only a little bit wide but it's lost > its gravity. And Eb-G and E-G# are watered down even more, each. > They're still smaller than Pythagorean ditones and they're pleasant > enough, in isolation, but they don't seem to fit their context. While A-C# is in my scheme unaltered, what you say about it definitely could apply to E-G# at 396 cents, the "double edge" of my possible argument regarding Bb-D, since E _is_ a natural, and the untransposed final for one of my favorite modes, E Phrygian, which comes up continually. While some other things are going in the piece which follows, I'd like people to hear the compromise of closing in Phrygian on that 396-cent third, which I accept, but wouldn't happen in a regular 2/7-comma: <http://www.bestII.com/~mschulter/Invocation-ToneIV.mp3> > Worse yet: we haven't really gained any usable B-D#, F#-A#, Ab-C, or > Db-F.

They just sound like "wrong notes" giving nothing > for my ear to grab onto, or to take me past the wincing. Certainly I'd agree, as a septimal fan myself, that having only one near-9:7 major third at Db-F, rather than four, is a compromise -- although one not so unpleasant for me, since in a neomedieval setting I also relish thirds around 408 or 421 cents, or anywhere along the spectrum from Pythagorean to septimal. This can be very much a matter of taste, with one person's "pleasantly variegated neomedieval thirds" being another person's "wrong notes." This more remote terrain in the circle is rather like a distinctively modern circle of another kind: a 17-tone well-temperament such as George Secor's of 1978, with major thirds at 418-429 cents. While Marchettus of Padua (1318) and the modern scholar and performer of medieval music Christopher Page provide a basis for concluding that thirds of around this size may have occurred in 14th-century performances of vocal music, this is above all a 20th-21st century keyboard concept rather than an historical one! Why don't I repeat for convenience the links to neomedieval pieces so that people can hear these thirds at 408 and 421 as well as 434 cents. <http://www.bestII.com/~mschulter/MMMYear001.mp3> <http://www.bestII.com/~mschulter/InHoraObservationis.mp3> <http://www.bestII.com/~mschulter/OElsa.mp3> It might not hurt for me to emphasize that these thirds are generally intended for use in a neomedieval context where they contrast with and often expand to stable fifths; or in a Renaissance context as meantone diminished fourths (B-Eb, C#-F, F#-Bb, G#-C). Apart from Eb-G at about 408 cents or Pythagorean, which I might use in a meantone setting in Eb-G-C or C-Eb-G, they are _not_ meant for use in a Renaissance style as usual thirds. Also, your remarks point to a basic consequence of circulation. The extreme values for major thirds, 383 and 434 cents, or very close to 5:4 and 9:7, are identical to those in a regular 2/7-comma. However, averaging out that Wolf fifth into four wide fifths results also in the intermediate values of 396, 408, and 421 cents. While I like these intermediate shades, they inevitably result in fewer major thirds at either extreme, at a near-just 5:4 or 9:7.

Here the different, of course, is that for my remote neomedieval transpositions Ab-Eb is going to come up all the time in Ab Mixolydian or Eb Dorian or Gb Lydian, etc. Where this kind of circulation isn't relevant, however, your solution very subtly optimizes the septimal intervals while leaving the smooth Renaissance meantone color undisturbed. > And by going back to regular 2/7, or nearly so (choosing septimal > placements on C#, G#, and Eb), we've got a fantastic set of eleven > minor triads, eight tightly attractive major triads, three septimal > major triads, and all the other related emoluments.

If the point was to get those septimal > resonances going, why move off them by widening the 5ths? Another way of phrasing this question: "What price circulation?" If I wanted to play in a Renaissance style around the circle, it wouldn't make sense. If something like Ab-C-Eb did occur, say in Schlick or an extended meantone piece assuming more than 12 notes per octave, having Ab-C at 421 cents would be just as much a barrier as a Wolf at G#-Eb. The answer is neomedieval styles in remote transpositions -- at the cost of fewer septimal resonances: Db-F at a near-9:7 as in the regular meantone, plus F-Ab and Bb-Db at around 275 cents, or not too far from 7:6. Now we have a 12-note circle where Bb-Db-F, for example, can cadence beautifully to Ab-Eb in Ab Dorian or Mixolydian, say. I'm quite happy with Eb-Gb and C-Eb at 287 cents also, another favorite size, so it's an amenable compromise to me -- but still a compromise! In short, from the viewpoint of septimal optimizations, I'd consider this one of the best 12-note circulating systems -- but not so good as a regular meantone! > I could change my mind tomorrow, but that's how I hear it today. > And all of this might work better (or worse?) on organ as opposed to > harpsichord.

Anyway, I'm delighted that your septimal variation fits your instrument well. > And if the notes D#, A#, Ab, and Db aren't going to come up in the > music anyway...why not just stick with regular 1/4 instead of 2/7? > It's sort of a trade-off here between the major 3rds and minor 3rds. > But if we wanted pure minor 3rds, why not go all the way to 1/3 > comma then? 2/7 goes down between these, giving the strengths of > both...and because those 3rds aren't pure, they're (arguably) more > attractive just by virtue of being livelier, not sitting there > dead-on.

They're beautiful in 16th-century chromatic progressions, and excellent as regular neomedieval semitones, very close to George Secor's ideal size of around 67 cents.

I've confirmed with my spreadsheet: 173/720 PC meantone should certainly be close enough to the mark for anybody with human hearing. Running 173/720 around to all twelve notes, the Eb-F# below middle C works out to beat less than 0.0052 per second (as a misspelled 7:6 minor 3rd) based on an A anywhere near 440. The eight major 3rds are each about -0.53 on Sorge's 11-point metric (where a Pythagorean ditone is 11). The four diminished 4ths are about 22.07 each, which is a smidge wider than a full diesis of 21. As for the phrase "extraordinary temperament" in the way I use it, here's my explanation from more than two years ago: http://www-personal.umich.edu/~bpl/larips/ordinary.html I use it to refer to circulating temperaments that happen to have E-G# wider than Ab-C. My page about TU and the Neidhardt/Sorge model of 21 schismas in a diesis: http://www-personal.umich.edu/~bpl/larips/tunits.html Each stack of three major 3rds has to add up to 21 of those. 1/4 syntonic comma meantone gives major 3rds of 0, 0, 21. 1/4 PC gives -1, -1, 23. 1/6 PC gives major 3rds of 3, 3, 15. The above-mentioned septimal thingy of 173/720 PC is about "halfway" between 1/4 SC and 1/4 PC, with its major 3rd sizes of -0.5, -0.5, 22. In practice on harpsichord that's such a small smidge in the major 3rds that it's hard to hear the impurity. And at A=440, the F under that A (middle of the treble clef) is narrow to it by only about 1 beat per second. Easier to hear by playing major 10ths instead of major 3rds. Brad Lehman

We may have a terminology conflict brewing. I first used the term _temperament extraordinaire_ a couple of years ago to refer to a 12- tone circulating temperament containing 2 or 3 fifths tempered wide by a small amount (<4 cents): http://groups.yahoo.com/group/tuning/message/59999 That was posted at the same time as the Lehman-Bach temperament was being discussed on this list, and I don't know whether you were using the term "extraordinary" at the time. (You needn't read the entire message, because I've summarized its essential characteristics below.) My original temperament was subsequently refined into one of a group of rationally-defined proportional-beating temperaments (both well and _extraordinaire_), which are listed here: http://groups.yahoo.com/group/tuning/message/66222 The updated original (and still best of the lot, IMO) is my 5/23- comma _temperament extraordinaire_ (which is probably not audibly different from the original version). A key feature of the _extraordinaire_ (as I use the term) is the <1/4- comma tempering of the narrowest fifths. In the 5/23-comma version, the fifths in the root-position C and G major triads beat at the same rate as the major 3rds, which hides the beating of the major 3rds -- so it sounds as if the major 3rds are just (as in 1/4-comma meantone), while the narrowest 5ths (tempered <4.7 cents) beat more slowly than in 1/4-comma meantone. (The minor 3rds, which beat exactly 4 times as fast as the 5ths, are also masked to some degree by the beating 5ths.) Since the 5ths are tempered less than 1/4 comma on the near side of the circle, there will be less error on the far side of the circle than with a comparable temperament having narrow 1/4-comma 5ths. In a nutshell, that's what makes it _extraordinaire_. However, in searching through back messages for "extraordinaire", I find that Margo may have used the term _extraordinaire_ for a temperament earlier than both of us (March 2003): http://groups.yahoo.com/group/tuning/message/42903 She indicates that she likes major and minor 3rds that approximate 11:14 and 11:13, respectively. The narrowest minor 3rds in my 5/23- comma temperament are all close to 11:13 (without getting significantly narrower), while the widest major 3rds are a few cents less than 11:14, so I may have met at least some of her objectives. In the last paragraph she mentioned a temperament of mine (of the _ordinaire_ class) that I previously suggested (in a personal communication a couple of years earlier) would be suitable for medieval music, if the far side of the circle of 5ths were used. That particular temperament has since been replaced by my 5/23-comma _extraordinaire_, so I believe we were thinking along the same lines when we (independently!) appropriated the term . --George

Please let me say what a pleasure it is for us to be in touch,

of nostalgia for old times.

Yes, one lesson of this may be that the phrase _temperament ordinaire_
naturally prompts the idea _temperament extraordinaire_. Maybe the
ways we've each used it might give curious clues about us <grin>.
Brad and George, I might say that for each of you, the aspect of the
tuning that makes it _extraordinaire_ might be rather subtle.
Brad, I very much enjoy your explanation of how the essence of the
"extraordinary" in your usage is having E-G#, traditionally a regular
meantone major third, smaller than Ab-C, traditionally a diminished
fourth -- a heritage reflected in many well-temperaments, and also in
the French _ordinaire_ where the fifths tempered wide tend to be on
the flat side (e.g. Ab-Eb-Bb-F in a very simple modification of
regular 1/5-comma, say). As developed in your reconstruction of Bach's
temperament, the idea that E-G# should be larger than Ab-C has some
fascinating ramifications.
George, while any tuning system you design is likely to be
"extraordinary," your _extraordinaire_ seems especially so in the
matter of coordinated beat rates. Again, this is a very subtle but
musically significant detail, a mark of craftspersonship possibly more
notable for its depth than its flamboyance.
In contrast, my _extraordinaire_ seems rather less refined. Take a
regular 1/4-comma or 2/7-comma meantone in 12 notes (Eb-G#), and
simply distribute the Wolf equally over four wide fifths, leaving F-C#
as is. The _extraordinaire_ aspect is not some fine nuance in the
gradation of sharps and flats, or some pleasant synchrony of beat
rates, but the sheer "colorfulness" of the thing: major thirds at
386-427 cents and minor thirds at 279-310 cents in 1/4-comma; and
respective ranges of 383-434 cents and 275-313 cents in 2/7-comma.
Of course, in March 2003 or now, to get excited about something like
this you have to a certain curious sensibility: for example,
applauding interval sizes like 421 cents as "delicious." But the idea
of my "extraordinaire" is mostly having a full spectrum of thirds
running most if not all of the way from 5-limit through Pythagorean
through 14:11 or 13:11 country and beyond to septimal.

Yes, I'd agree that our systems share this connecting theme. A
distinction might be that yours does this as part of a very subtle
balance within the circle. In contrast, my approach is to seek a
spectrum reaching out into at least the "suburbs" of the septimal
realm, as reflected in my remarks in that same post about
approximations of 4:6:7:9 -- but without the kind of nuances and
careful planning that might be the mark of a more discriminating
designer.

Yes, your comments in our correspondence of 2001-2002 about that
earlier temperament were germinal to my 1/4-comma and 2/7-comma
variations. Even a regular meantone, of course, can demonstrate the
basic idea, as when in 1998 or 1999 I not surprisingly found myself at
a 1/4-comma keyboard playing
Eb E Eb F
Bb B Bb C
F# E or F# F
Your communication as part of our discussion as a "Committee of
Correspondence for the 17-tone revolution," however, was what
presented me with the realization that this kind of thing could be the
basis for a 12-note circulating system.
Anyway, I can offer my part of a solution to "disambiguate" things a
bit on "extraordinary" or _extraordinaire_ tunings. Since the
distinctive thing to me about my modified 1/4-comma and 2/7-comma
tunings is the "encompassing spectrum" of thirds from 5-limit to
near-septimal in a 12-note circle, I'm drawn to the names:
Quest: QUarter-comma Encompassing Spectrum Tuning (based on 1/4-comma)
Zest: Zarlino Encompassing Spectrum Tuning (based on 2/7-comma)
How does that sound, George and Brad?
Or, maybe I could still let the "e" in Quest or Zest stand for
"Extraordinaire," but with an understanding that I would use Quest
or Zest or whatever as the specific name for mine, George, so that
"temperament extraordinaire" or TX could remain a more distinctive
name for yours while the common roots would still be explicit. That
might also be influenced by how the two of you approach your own
usages of "extraordinare" and "extraordinary."
By the way, Brad, I must say that your dialogue with me about your
2/7-comma harpsichord experiments has been most educational for me,
and makes me resolve to strive for accounts of these spectrum tunings
as lucid as yours about "extraordinary" ones. In fact, reading your
explanation on "ordinary" and "extraordinary" has given me some ideas
I might share here.
Thanks to both of you as teachers and people who make things more fun.
Most appreciatively,
Margo
From: Tom Dent (2007-11-02) Subject: Re: Septimals and TU Thanks to Margo for her persistence in arithmetic. However, one should note two things: In order to start off the whole calculation, one had to look up the cent value of 64:63, and then convert it to TU via some rather unmemorable string of decimals. At the end of the calculation the value of the fifth, and the resulting meantone scale, are again presented in cents, using the same ugly conversion factor in reverse. So yes one can use TU, but they seem here to be completely equivalent to doing the calculations in cents with two extra steps to convert both ways. Like measuring things in centimetres, then calculating in hundredths of an inch, then converting back to centimetres to test the calculation. The point is, can one determine 64:63 *directly* in TU without any help from cents? There must be a formula, but I expect it's pretty complicated. To deal with it at all conveniently one would have to memorize the fraction that defines the Pythagorean comma. Cents is easy enough: 1200*log(64/63)/log(2). ~~~T~~~ --- In [email protected], Margo Schulter <mschulter@...> wrote: > > we know that the net tempering of those three fifths has to be > equal to the septimal comma or Comma of Archytas (thanks to George > Secor for the latter name!) at 64:63, 27.26 cents, or 836.75 TU.

Specifically, i'm approaching this two different ways in Tonescape: 1) a .tonespace file which sets up 7-limit JI and then tempers it via 2/7-syntonic-comma and whatever the other unison-vector should be (i'm guessing that it's some fraction of 64:63); 2) a .tuning file which uses two tempered generators: one for the -189 TU chain-of-5ths, and another one for the +198 TU chain.

When using tempered generators, there's always some ambiguity about how chains of different generators intersect. In this case, i've used "A" as the origin, and the 2/7-comma chain extends from "F" at -5 to "C#" at +4, but the other chain can extend from either of those endpoints, and in fact is supposed to connect both of them ... but i can only do that with #1. -monz email: joemonz(AT)yahoo.com http://tonalsoft.com Tonescape microtonal music software

Duh ... i guess i had a brain fart. It wasn't that difficult to figure this out after all: since it's a 12-tone tuning intended to have the same structure as many historical 12-tone tunings, it's obvious that there should be two small +198 TU chains, one extending in the negative direction from F to give Bb and Eb, and the other extending in the positive direction from C# to give G#. D#/Eb is the unison-vector. But i do still need help figuring out how to incorporate 7-space into #1 (the .tonespace file). -monz email: joemonz(AT)yahoo.com http://tonalsoft.com Tonescape microtonal music software

If you make all of the narrowest fifths exactly the same size (as you suggest below), you've *irrationalized* them. That's the way I started out, in fact, but I soon discovered that the beating in the *minor* triads was not exactly proportional. > !

In my brief explanation I didn't point out that other major triads (from Eb to E) and many of the minor triads also have *exact* proportional beat rates. This is not the case with a single size fifth, in which they're approximate. Exact proportional beat rates tend to make the beating sound more unified (or periodic), like a vibrato, as if the instrument is "singing". With non-proportional beating, the interactions between the differing beat rates sounds more disturbing.

The rational numbers are precise, i.e., they result in *exact* proportional beat rates within the various triads.

Granted, the fifths > don't beat as fast, but I think the claims about the thirds are inflated. The thirds beat if they are sounded separately, but within a triad they're masked by the beating fifths, because the beat rate of both is the same. I think it's preferable to have both intervals beat at the same rate, as opposed to one beatless and the other beating, because the contrast in beating vs. beatless intervals tends to make the beating more conspicuous. You need to compare the C and G triads in the ~5/23-comma rational temperament (not an oxymoron!) with 1/4-comma meantone temperament (which also has proportional-beating triads, BTW). The question to ask is whether one sounds better than the other. If the difference is judged to be very small or insignificant, then the rational temperament will be a better choice as a starting point for a circulating temperament, because there will be less total error on the far side of the circle of fifths. > > In a nutshell, that's what makes it > > _extraordinaire_. > > What?!

The major-3rd-to-fifth beating for those two triads is 1:1 in all (close) triad positions, except that you need to substitute the fourth for the fifth and (for the 1st inversion) the minor 6th for the major 3rd. In the other major triads the proportions are different, yet still fairly simple; e.g., the ratio of the minor-3rd-to-major-3rd rates is 2:1 in the E and F major triads and 3:1 in D major. In the minor triads the proportions are not quite as simple, but the effect is still better than if the ratios between the rates are unplanned (i.e., haphazard). > Oh well, I guess it IS the era of > reduced expectations... > > :-( Or an era of increasing explanations. :-) --George

Well, I have to admit that after a half hour of staring at my large monitor (19" wide) and my big chart which graphically shows the beat rates of every major and minor triad over two octaves (thirds and fifths), I haven't got the foggiest notion what you are on about. When I switch back and forth between the regular-sized fifth version and your irregular sized fifth version, the movement of the traces is so small that it can hardly be seen (full scale is 25 b/s, so we're talking about 6mm or so for every 1 b/s - pretty darn easy to see changes that would be nigh to impossible to hear). If I set the trace value indicators to 2 decimal places, it also tells me that the change only affects a very few triads, and the largest change is in the area of than 0,01 b/s. That means you are going to have to hold a triad for about 100 seconds while you do nothing else musically to distract the ear from the extremely subtle gradual drift of phase between third and fifth or third and third beat rates. Do you REALLY think this is an advantage? Just wonderin'... Ciao, p

It shouldn't be any more complicated than calculating cents, because it's the same operation. The only complicating aspect is that you have to take the log to base-pythagorean-comma instead of base-2. However, when i actually did the calculation, i got the wrong answer. So maybe Gene can help. Here's how i did it (wrong) in Open Office Calc: =log(64/63;pythagorean_comma)*720 where "pythagorean_comma" is a reference to a cell which contains =(2^-19)*(3^12). -monz email: joemonz(AT)yahoo.com http://tonalsoft.com Tonescape microtonal music software

Looks like it ought to work. What was your numberical result? It should be 720 log(64/63)/log(P), where P is the Pythagorean comma and log is log base anything. As Margo obtained, the result is ~ 836.75 By the way, if you want to temper out the atom and get 7-limit intervals accurately, 11664, 21480 and 33144 are all recommendable. If all three commas are supposed to have nice divisibility properties, that adds another twist, but for instance you can assign 1728 to the Pythagorean, 1584 to the Didymus, and 2008 to the septimal commas by using 88380-et. 21480 has 420, 385, 488, and etcetera.
From: Tom Dent (2007-11-03) Subject: Re: Septimals and TU OK, my mathematical training tells me that 64/63 in TU should be 720 * log(64/63) / log(531441/524288) compare cents : 1200 * log(64/63) / log(2). The TU formula requires eleven extra characters, which is why it is unlikely to catch on. Can't help with Open Office, I'm afraid. My main objection to TU is that they are absurdly and spuriously tiny for any realistic acoustic situation. What is the point of an organbuilder using a unit which is probably at least ten times smaller than any interval he could reliably or usefully adjust his temperament by? Thinking in TU carries a great risk of attributing a pseudo-scientific precision to what is, in reality, the rather messy, unpredictable and artistic process of actually tuning organ pipes. Didn't Brad tell us not too long ago about tuning a small organ for continuo accompaniment ... one of the remarks there was that the reading on an electronic pitch meter was chronically unstable, and thus useless for calibration or setting temperament, and this was a normal situation for certain types of register. Also, I know that if one tunes the pipe with the lid of the portative organ off, then replaces the lid, some relevant intervals may change noticeably - probably by dozens of TU. So what use are TU there? Can one ever hear or control *one* TU? Cents have probably stayed in use partly because they do correspond quite closely to the minimum audible difference between intervals in some relevant situations - for example tuning fifths on a keyboard instrument. By the way, my solution was as follows. Nine fifths F-G# have to have a total (flatwards) tempering of one comma plus 64/63. In my third-(syntonic)-comma / septimal scheme that is seven steps, since 64/63 is represented by 4/3 comma. Hence the tempering of each fifth is one-ninth of 7/3 comma, ie 7/27 (syntonic) comma. So far, not a single logarithm or decimal in sight... This then comes to 5.58 cents, which is about 0.05 cents less than the exact result. My error on 7:6 is about half a cent. As a musician: forget it. The next exercise: Take the intervals 5:4, 6:5, 7:6 and 9:7, along with their meantone approximations via a chain of 4, 3, 9 and 8 of the regular fifths respectively. What meantone minimises the maximum error of these intervals? My nearly-exact method gives, relatively simply, 5/18-comma, which is interesting given that Smith didn't care about septimal intervals. The four thirds are tempered by about 1/9, 1/6, 1/6 and 1/9 comma respectively. Has there been some systematic study of how to find the meantone that minimizes the maximum error on some given collection of intervals? ~~~T~~~ --- In [email protected], "monz" <monz@...> wrote: > > Hi Tom and Gene, > > > --- In [email protected], "Gene Ward Smith" <genewardsmith@> > wrote: > > I always understood the TU to be defined as a logarithmic > 1/720 of a pythagorean-comma.

Thank you for this feedback, and I will be delighted to write entries for these tunings in their 12-note and 24-note versions (the latter with two circles at the distance of the regular meantone's enharmonic diesis). At the conclusion of this message, I'll provide some Scala files, although I'm not sure about the best representations for your Tonescape software. Please let me emphasize that your editorial ideas would be invaluable, because my desire is above all to communicate some real-world musical qualities of these tunings. Brad's post about his impressions of 2/7-comma variants is very helpful, and of course he and anyone else interested would be welcome to join in the dialogue. While I'll write some drafts for these texts, I feel that it would best be an active collaboration, with you as an especially logical participant because you know the style of the Encyclopedia. I want something that people coming from different backgrounds can understand. They may or may not like the tunings, but a good presentation should help in understanding some possible reasons why or why not.

Depends on a many different factors, far too many to list here, but yeah, organ pipes are notoriously unstable in any sort of super precise terms. You don't need any electronic device to see it, either. Just compare the sound of any pipe to an electronically generated tone (with a reasonable amount of harmonics) by listening to the pipe through a pair of non-isolating headphones. The slight wavers produced by random phase shifting is readily audible. Furthermore, don't forget that the frequency of a pipe changes by about 3 cents for every degree C of temperature! So you'd better move fast when tuning an organ. See: http://hyperphysics.phy-astr.gsu.edu/hbase/waves/opecol.html BTW, I don't know what sort of "electronic pitch meter" Brad uses, but if it is a Korg, forget it! Those things are utterly worthless, inherently unstable, and so poorly programmed that even the octaves are often out of tune. > Also, I know that if > one tunes the pipe with the lid of the portative organ off, then > replaces the lid, some relevant intervals may change noticeably - > probably by dozens of TU. A common problem, due to the lid shading the pipe. Worse yet, in portatives, the pipes are packed so close to one another that they interact acoustically, so tuning one pipe can mess up the tuning of another already tuned, merely because the process changes the impedances of the ambient field. > So what use are TU there?

Yeah, there is a pretty good theory/practice correlation with cents, though the main problem is that we hear beats and not interval size, and beats are linear while interval size is log. That's why we can tolerate a relatively large detuning (in cents). Often, when the tuning of an organ goes all wanky during a rehearsal and I've only got 45 minutes to clean it up AND retune the harpsi before the concert, I don't even touch the bass pipes. Nobody knows. TU, like so much of what seems to go on here, is nothing more than having fun with numbers. Great way to pass the time if you're so inclined, but in the real world is has no application. Ciao, P

I have never had *any* "electronic pitch meter", Korg-esque or otherwise. All my tuning is by ear, from any of several individual tuning forks. A couple of months ago I listened patiently to a professional full-time piano tuner showing me and enthusing about his Accu-Tuner, an approximately $2000 device that is supposedly programmable in some zillion different ways, but I still don't want one.

That's no problem ... i can make the Tonescape .space file when Gene (or whomever else) helps me with the question i asked about how Zest tempers the 7-space. And i already have a .tuning file for it. It's easy enough to create both of these types of files for all the other versions of these tunings, once i'm sure about how they work. If you have access to a Windows XP computer, you can now download Tonescape free and hopefully get it installed properly. (Lots of people have had problems installing it because of incompatibilities between different versions of DirectX.) Then you could compose your own pieces in it using these tunings. Anyway, i'll certainly make a few, or if you have any scores of period pieces which you think would illustrate them that would be even easier for me. I'll make all of the these Tonescape files available via links on the Zest and Quest webpages.

No, my complaint was that the definition as I understood it was unsatisfactory. If it's just another logarithmic measure like cents, that's precise enough. Whether it helps is another issue.

Subject: Re: Temperament extraordinaire? (was: Septimals and TU)
Dear Monz,
Please let me say that having seen some of your posts asking for
assistance as to how Zest-12 might be mapped to a JI-style lattice, I
would like at least to share my views as the designer on some of the
ratios that might be represented. How you would best map this in your
application sounds like a more complicated question, because you know
the technical practicalities and I don't.
Why I don't a give quick summary of the categories of major and minor
thirds? Certainly we can agree that the nearest range F-C# represents
5-limit meantone, while the thirds C#/Db-F, Bb-C#/Db, and F-G#/Ab
represent ratios of 2-3-7, the first 9:7 and the other two 7:6. It
gets more complicated when we consider how a combination of small and
large fifths in a chain can, in effect, disperse other kinds of
commas.
I'm not sure if I'm doing you a favor here by mentioning yet more factors
to consider diagramming. However, my purpose is only to explain how I tend
to interpret the different third sizes, leaving to you the consideration
what is possible, realistic, or elegant to include in a lattice diagram.
------------
MAJOR THIRDS
------------
Obviously the regular meantone thirds F-A, C-E, G-B, D-F#, and A-C# at
383 cents, built exclusively from small fifths, represent 5:4.
The thirds Bb-D and E-G# at 396 cents, built from three small and one
large fifths, may be considered rather compromised 5-limit thirds
also. Indeed I often quote the usual "meantone-like" range as Bb-G#,
which implies that these thirds are meant to be interchangeable with
the near-pure ones.
The thirds Eb-G and B-D# at 408 cents, built from two small and two
large fifths so that the two directions of temperament almost cancel
out, are in effect representations of the Pythagorean 81:64, and
generally are meant for a neomedieval rather than meantone style.
Sonorities like Eb-G-C or C-Eb-G, however, do come up as touches of
"modal color" in a meantone setting.
The thirds F#-A# and Ab-C at 421 cents, from three large and one small
fifth, might be taken as not-so-accurate representations of 14:11,
although 23:18 is also a possibility. These are very characteristically
neomedieval, and not too far from 17-EDO -- but 14:11 or 23:18 seems
to me the likely JI interpretation.
The third Db-F at 434 cents from four large fifths is a near-9:7, and
here the lattice clearly enters septimal territory.
------------
MINOR THIRDS
------------
The thirds D-F, A-C, E-G, B-D, F#-A, and C#-E at 313 cents are again
regular meantone intervals representing 6:5, from three small fifths
(or large fourths).
The thirds G-Bb and G#-B at 300 cents built from two small and one
large fifth have an ambiguous interpretation, with an inexact 6:5 in
meantone or 32:27 in a neomedieval as likely historical associations.
Sometimes 19:16 is also a possibility, as for example with G-Bb-D used
in a style around 1500 as a closing sonority for G Dorian, say; this
third might to some modern listeners, at least, actually be more
conclusive than a near-just 6:5, although Bb-D is 8 cents narrow of
the 24:19 in a just 16:19:24. Also, something like D-F-Ab/G#-B might
be interpreted as 15:18:21:25, with G#-B at 300 cents as 25:21.
The thirds C-Eb and Eb-Gb at 287 cents, built from two large and one
small fifth, closely represent 13:11, or also 33:28, and might also
represent a variation on the traditional medieval 32:27.
The thirds F-Ab and Bb-Db at 275 cents, from three large fifths (or
small fourths), represent 7:6, and are almost precisely at 75:64.
Again, we are clearly in septimal territory, albeit not without some
compromise.
To sum up, here are the ratios I might suggest are likeliest
candidates, trying to focus on a few main themes:
MAJOR THIRDS MINOR THIRDS
383 cents 313 cents
5:4 6:5
396 cents 300 cents
5:4 6:5, 32:27
(more impure)
408 cents 287 cents
81:64 13:11, 32:27
421 cents 275 cents
14:11, 23:18 7:6
434 cents
9:7
With many thanks,
Margo

If you're saying, for all practical purposes, there's no audible difference between slightly varying fifths with rational ratios and like fifths with irrational ratios, then yes, you're right. OTOH, I could turn that around and say that there's no advantage of the like fifths with irrational ratios over slightly varying fifths with rational ratios. Using rational fifths enables me *to define the tuning* in such a way that the proportions between the beat rates are *exact (usually simple) rational values* in both major and minor triads, so there is a *theoretical* advantage for doing this.

Subject: Zest-12 cadence with ~14:18:21:25
Hello, everyone.
Many thanks to Tom Dent, who in a recent discussion of possible
tunings for certain Baroque pieces, noted that in some circumstances
meantone diminished fourths might be used in conventional tonal
progressions. Applying this insight to my own modal style in its
"Manneristic" aspects, I came upon a cadence that might be of
interest.
<http://www.bestII.com/~mschulter/zest12-cadence001.mp3>
<http://www.bestII.com/~mschulter/zest12-cadence001.pdf>
Tom's idea was a "dominant" sonority spelled in his message as
C#-B-F-A, suggesting to me also the possibility of C#-F-G#-B in the
rather different kind of musical syntax I often follow.
In Zarlino's 2/7-comma meantone, and also in my encompassing spectrum
tuning of 2003 (then called a "temperament extraordinaire") based on
this regular tuning, C#-F at about 433.52 cents is very close to
9:7. Thus C#-F-G#-B gives a rather good approximation of 14:18:21:25,
a sonority which George Secor called to my attention in October 2001
as a pleasing use of 9:7. More specifically, he favored 14:18:21:25:28
including the octave, with its many mixed isoharmonic differences of
3, 4, and 7; but my progression in four voices uses the simpler
14:18:21:25.[1]
Here is the progression, notated again in a usual meantone spelling,
with C5 indicating middle C; as it happens, all notes and intervals
used are identical to those of Zarlino's regular tuning. See also the
link above to a PDF score:
1 2 + | 1 + 2 | 1 2 + | 1 2 ||
B5 B5 B5 C6 C6 C6 C6
G#5 G#5 G#5 G5 A5 A5 A5
F5 F5 F5 E5 D5 E5 F5 F5 F5
C#5 C#5 C#5 C5 F4 F4 F4
A curious feature of this cadence is that the outer minor seventh of
the opening sonority, which we might often expect to contract to a
fifth by stepwise contrary motion, insteads expands in this fashion to
an octave! Likewise the upper minor third, instead of contracting to a
unison, expands to a fourth.
From this point of view, the seventh B5 might actually be viewed as a
kind of surrogate for Bb5, which would yield a major sixth sonority at
approximately 14:18:21:24. With this more conventional note, and the
progression otherwise identical, we would have a major sixth C#5-Bb5
expanding to an octave, and an upper major second G#5-Bb5 expanding to
a fourth.
While the "substitution" of the minor seventh for the major sixth
might be considered a kind of rhetorical figure -- see below -- in
other ways this is typical "Xeno-Mannerism." A sonority with a tritone
or augmented fourth -- here F5-B5 -- characteristically serves as an
antepenultimate leading up to a cadential 4-3 suspension. This might
contrast with tonal harmony, where tritonic sonorities often play a
penultimate or "dominant" role.
Also, the motion of the bass, descending first by a step and then by a
fifth, is very characteristic both of historical Renaissance and
Manneristic cadences, and of 21st-century offshoots such as this.
Typically the stepwise descent is part of a resolution from major
sixth to octave with an upper voice ascending by a whole tone, leading
into a 4-3 suspension between the bass and another voice, which then
ascends by a semitone while the bass descends a fifth.
This cadence varies only in that instead of an initial expansion from
major sixth to octave, as already noted, we move from a minor seventh
to an octave, which both outer voices moving by a semitone -- the
minor semitone of 25:24 or about 71 cents in the bass, and the regular
diatonic semitone of Zarlino's meantone at 121 cents in the soprano!
A fine point of contrapuntal style might involve the parallel fifths
between bass and alto moving from the first to the second measure
(C#-G# to C-G). Possibly one might argue that since the minor or
chromatic semitone could be considered only a matter of "coloring,"
this might be excused as analogous to repetition of a fifth without
melodic motion! However, a better approach might be frankly to
recognize that some of the normal liberties of historical medieval and
neomedieval writing, where parallel fourths and fifths are freely
used, are sometimes "imported" into Xeno-Manneristic idioms.
Conventional meantone progressions would be more likely to observe
16th-century proprieties.
Now for the concept of a rhetorical figure. In defending Monteverdi's
bold uses of the minor seventh around 1600, treated rather more
cautiously in a conventional 16th-century style (where it appears
prominently mainly as a suspension), an academic writing under the
name of "l'Ottuso" argues as follows:
"[Y]ou allow an excellent poet the metaphor
purposely used; similarly the seventh is taken
in place of the octave."[2]
Here a minor seventh (C#-B) is taken in place of an expected
near-septimal major sixth (C#-A#, or C#-Bb in a usual meantone
spelling). Possibly this experiment in modern mannerism could serve as
a tribute to the Monteverdi brothers (Claudio and his literary partner
Giulio Cesare) for the 400th anniversary of their manifesto of 1607
defending the modern practice of the previous six decades or so
against those who could see Zarlino's classic rules of counterpoint as
the only ones conceivable.
While the free uses of the seventh by Monteverdi and his contemporaries
became one ingredient of major/minor tonality in the later part of the
17th century, he and his brother in 1607 notably championed a style
drawing on a variety of modes as might be required to express the
ideas and emotions of a given text. It is interesting that precisely
this concept had been championed in 1555 by Nicola Vicentino, who with
his archicembalo and 31-note meantone cycle might be described as the
greatest xenharmonicist of the 16th century.
It is thus as a meeting place of old and new that I share this
cadence.

1. Interestingly, George's colleague in so much of the development of
the Sagittal notation system, David Keenan, briefly mentions
14:18:21:25 as a possible tuning for the tonal dominant seventh in
a Tuning List post of 1999.

From: Margo Schulter (2007-11-06) Subject: Pieces for Zest-12: PDF scores Hello, everyone. Here are some new PDF scores for two pieces in the Zest-12 tuning, along with links to mp3 files which I've previously posted. Of course, these pieces could be played on _either_ 12-note keyboard of a full Zest-24. I hope that Monz, Brad, and others may find the scores helpful in following the different shadings of thirds from regular 2/7-comma meantone to septimal, for example. <http://www.bestII.com/~mschulter/IntradaFLydian.pdf> <http://www.bestII.com/~mschulter/IntradaFLydian_regbars.pdf> <http://www.bestII.com/~mschulter/IntradaFLydian.mp3> <http://www.bestII.com/~mschulter/OElsa.pdf> <http://www.bestII.com/~mschulter/OElsa_BbDorian.pdf> <http://www.bestII.com/~mschulter/OElsa.mp3> Each PDF score has two versions. For _Intrada in F Lydian_, I have provided a version with more flexible barring, and one with relatively more regular barring (including however some alternating 2/2 and 6/4), in an effort at least partially to accommodate different tastes. For _O Elsa_, I have provided a transposed version in Bb Dorian which is played in the mp3 recording, thus bringing the piece into the remote portion of the Zest-12 circle; and also the original version in D Dorian, fine for routine singing or playing in medieval Pythagorean intonation, for example, or a regular neomedieval variant like the Peppermint temperament. In the score for _Intrada in F Lydian_, I sought to follow the expected augmented or diminished spellings for near-septimal intervals like Bb-C# at 274 cents or F-C# at 766 cents, so that people playing in a regular meantone around 1/4-comma or 2/7-comma would likewise get septimal colors. Indeed, when I play the piece in regular 2/7-comma it sounds fine, and likewise in regular 1/4-comma or Quest-12 (the latter corresponding to Zest-12 for 2/7-comma). The most dramatic differences concern sonorities involving Eb, which in the score retains its usual spelling although it is actually located precisely halfway between Eb and D# in a regular 2/7-comma. Thus F-A-Eb (opening of the second page in either version of the score) is about 0-383-983 cents, a 4:5:7 approximation comparable to that of 22-EDO, but a usual 0-383-1008 cents in a regular Eb-G# tuning. Also, Eb-G-C is 0-408-913 cents, having a Pythagorean flavor rather than the usual 5-limit smoothness of 0-383-887 cents in the regular tuning. These distinctions of color "go with the territory" in moving from one system to the other, and tastes may vary. Please enjoy. With many thanks, Margo

The Tonescape .tuning file i made uses "A" as the
origin, with the 2/7-comma chain-of-5ths running
from -4 = F to +4 = C#. The chain of wide fifths
is actually split into two parts: F:Bb:Eb on the
negative meantone side, and C#:G# on the positive side.
Here's an ASCII lattice with integer cents values:
(use the "Option | Use Fixed Width Font" link to view
properly on the stupid Yahoo web interface.)
G#
1092
|
F --- C --- G --- D --- A --- E --- B --- F# --- C#
817 313 1008 504 0 696 192 887 383
|
Bb
108
|
Eb
600
If i use exactly these same pitches but call "C"
the 1/1 instead, i get the values in your Scala file.
So now that i have all that straight, i can use
the .pdf scores you posted to create some .tonescape
Musical Piece files of your pieces.
But i'd still like to have the other version of
the Tonescape .tuning files, which i've asked Gene
to help me with, and which use tempered 3, 5, and 7
as the generators.

Dear Aaron, Please let me explain that as I originally saw this, describing this as a special form of temperament ordinaire would be quite correct, and thus "temperament extraordinaire." Indeed we have most of the fifths in a regular shading of meantone (2/7-comma), with a few tuned wide of pure. However, I've concluded that indeed the technical resemblance might be confusing, as you say, as to the outlook and purpose of this 21st-century approach. Specifically, a temperament ordinaire, like a more moderate 12-note well-temperament, will typically strive to make more major thirds "usable" _in a 5-limit style_ than would be so in a regular 12-note meantone, where there are eight available. In contrast, the Zest-12 tuning actually _reduces_ the number from eight to seven, with the traditional four diminished fourths staying Pythagorean or larger and Eb-G also becoming a tad larger than Pythagorean. To put it another way: we get five great neomedieval major thirds! That, however, evidently wasn't the goal of Couperin and his colleagues and successors in the art of the temperament ordinaire, although it might be fun to imagine them launching a revival of Machaut around 1700 and relishing the remote transpositions for this purpose! Thus Zest may better fit something new, and keep alternative history a bit more distinct from actual history where confusion could indeed result. > Have you tried a variant of this with 5th size ~695.63? (see the > recent G. Secor post on MMM re:metameantone-19) Actually I discussed some of the resources of this variant in a paper on what I was then still calling the temperament extraordinaire, where Wilson's Metameantone is treated as a very significant point on the spectrum from 1/4-comma to 88-EDO or so: <http://www.bestII.com/~mschulter/TE1.txt> The main complication on a 1024-EDO synthesizer like the TX-802 is that this division is much kinder to Zarlino's 2/7-comma than to Wilson's Metameantone, so that the former actually becomes one not unreasonable approximation of the latter. In brief, the problem is that the right combination of fifth sizes will produce a major third almost identical to Zarlino's; Wilson's is located much closer to halfway between the nearest two available values. A MIDI-based realization or the like using 49152-EDO, for example, obviously wouldn't have this problem. Here's a Scala file for West-12, the Wilson Encompassing Spectrum Tuning. ! west12.scl !

Here's my answer: 53-edo is a decent approximation to 5-limit JI, and a superb approximation to 3-limit pythagorean. Its chief drawback in approximating 5-limit JI is that it does not distinguish the skhisma (~2 cents). 612-edo retains all of the closeness of approximation of 53-edo but also distinguishes the skhisma. -monz email: joemonz(AT)yahoo.com http://tonalsoft.com/support/tonescape/help/tonescape-overview.aspx Tonescape microtonal music software
From: banaphshu (2007-11-10) Subject: Re: Pieces for Zest-12: PDF scores (not on my computer so a bit difficult) one feature that i thought might be useful is that while metameantone converges on a particular size, it is also a recurrent sequence which could be seeded with other meantones. my own observation has been that i actually prefer many of the recurrent sequence before they actually reach too near a convergent point. Wilson provides an example of metameantone being seeded with a just major scale in the archives

It is equivalent to approximating the Pythagorean comma with > 1/51 octave, but is this relevant? What's relevant is that it is extremely accurate. If we call one step of 612 "sk", then the fifth is 357.997 sk, the majr third 197.020 sk, and the minor third 160.977 sk. Hence these can be rounded off to integer values and iterated multiple times, and still give the best values. Also, the Pythagorean comma is 11.965 sk whereas the Didymus comma is 10.968, so the approximate 12:11 relationship is captured. The schisa of 32805/32768 is 0.9964 sk, so the unit is an apprimiate schisma and quite close to the correct value.
From: Margo Schulter (2007-11-13) Subject: Re: Suggestions wanted for wise choice of pitch Dear Justin, Please let me warmly thank you for this opportunity to learn more about Japanese music and its intonation. A possible just tuning has occurred to me which is not too far from the melodic steps you describe, and on which I would warmly invite your comments. First, however, I would like to express my clear and strong opinion that some genres of Japanese music are indeed polyphonic. In gagaku, the classical court orchestral music, various kinds of complex sonorities with several voices sounding at once are a basic feature of the style. It is said that these sonorities are built from superimposed fifths or fourths, as also happens in some 20th-21st century European music, both classical and more popular. This is also true for music played on the sheng or "mouth organ," also common to the music of China, Laos (where it is known as the khene and is a treasured national instrument), and in certain Cambodian traditions. Further, Japanese koto music often is polyphonic, in that it uses two or more notes sounding at the same time. A very beautiful sonority, for example, may involve the fifth at 3:2 or 702 cents in JI, and a major ninth at 9:4 or 1404 cents; interestingly, this happens both in medieval European music for voices and in modern Japanese koto music. Here is the seven-note tuning which I mentioned above: ! ForJustin001.scl ! Scale for Justin, possibly applicable to Japanese modes 7 ! 22/21 33/28 4/3 3/2 11/7 39/22 2/1 If I understand correctly, one five-note or pentatonic mode often used is as follows, and may be found within this seven-note tuning: ! ForJustin-pentatonic001.scl ! Pentatonic mode for Justin, possibly applicable to Japanese styles 5 ! 22/21 4/3 3/2 11/7 2/1 As I hope these scales will show, just intonation often presents simple and beautiful musical solutions. The question remains, however, as to whether a solution fits a particular kind of melodic or harmonic style. Here I picked a semitone at 22:21, around 81 cents and thus slightly larger than the 75 cents you mentioned, but maybe not too much larger. One possible advantage of this semitone is that it produces a minor sixth at the just ratio of 11:7 or 782 cents, which might, for example, be heard if the use of a drone were made. In the five-note or pentatonic scale, all fifths and fourths will be at their pure ratios of 3:2 and 4:3. If I understand correctly, these are the primary consonances in styles of Japanese music such as gagaku, sheng, or koto playing where two or more simultaneous voices are common. In the seven-note scale, there are some compromises, but not, I hope, too severe. In the six locations for fifths, we find that four of them remain at a pure 3:2, but two of them have intervals at about five cents wider at the almost identical ratios of 182:121 or 176:117. These two wide fifths differ by the very small amount of 10648:10647, or 0.163 cents, less than a sixth of a cent! In practice, except on a computer or the like, the tuning of course would be not nearly this precise. I am not sure if fifths about five cents wide would fit this kind of Japanese style. In the pentatonic or five-note scale, however, all fifths and fourths are pure; I would be curious how you like either scale. With many thanks, Margo [email protected]

I don't know much about it I'm afraid. The sho chords are quite strange! Nice effect. Takemitsu Toru wrote a modern gagaku composition which is very nice. There is a whole CD of it.

Here I would like to share some mp3 files of cadential progressions
involving reasonably close approximations of many of these NI sizes as
found in the 24-note Zarlino Encompassing Spectrum Tuning, or Zest-24.
In short, an interval of around NI size may represent the zone of
maximum harmonic complexity between two simpler ratios. For example,
the 5:4 major third at 386 cents and 9:7 major third at 435 cents may
have an intervening region of "gravitational equipoise," or maximum
complexity, at around 422 cents.
The paper explains David Keenan's ingenious process for estimating
this NI value by using a Phi-weighted mediant of the two simpler
ratios. Here, however, the purpose is not so much to analyze this
process as to hear the audible results.
Zest-24 is called an "Encompassing Spectrum Tuning" because it surveys
many different regions and subregions of interval space. In my notes
for the mp3 examples which follow, I describe these regions in terms
which hopefully will be reasonably self-explanatory, but are more
fully developed in my newly completed paper exploring one possible
approach to the interval spectrum.
<http://www.bestII.com/~mschulter/IntervalSpectrumRegions.txt>
As mentioned at the beginning of this paper, I am much indebted to the
very thoughtful and musically sensitive writings of David Keenan on
interval names and regions and much else. Our counterpoint of ideas,
like a musical counterpoint, seems to proceed now by similar and now
by contrary motion.
<http://users.bigpond.net.au/d.keenan/Music/>
The Zest-24 system uses two 12-note circles of a modified meantone
tuning based on Gioseffo Zarlino's 2/7-comma meantone. Each circle has
eight regular meantone fifths (F-C#), with the other four equally
wide; the two circles are at the distance of Zarlino's meantone
diesis, 50.276 cents. A Scala file is included at the end of this
article.
The name for each mp3 file starts with "NIA" for "Noble Intonation
Approximation," and includes the sizes in rounded cents for the
relevant NI approximations used in a given example. Here I have
specified the sizes which theoretically should occur in my specific
synthesizer realization of Zest-24 in 1024-EDO, which may sometimes
vary by something on the order of a cent from the values appearing in
the Scala file below.
----------
EXAMPLE 1.
----------
<http://www.bestII.com/~mschulter/NIA001-422.926.mp3>
This example includes two simple and very characteristic neomedieval
cadences using a 422-cent major third and 926-cent major sixth, the
first virtually coinciding with the estimated NI zone at 422 cents or
so, and the second slightly wide of this zone at around 923 cents.
The sonority Ab-C-F (or G#-C-F in a typical meantone spelling) found
in either 12-note circle includes these intervals. The resolution has
the major third expand to a fifth and the major sixth to an octave.
----------
EXAMPLE 2.
---------
<http://www.bestII.com/~mschulter/NIA002-337.829.mp3>
This example features the small neutral third and sixth at 337 and 829
cents, not too far from NI values of 339 and 833 cents -- these
intervals, in either shading, may also be called supraminor thirds and
sixths. Here the third expands to the fifth, and the sixth to the
octave. A helpful spelling might be C-Eb*-Ab*, with the asterisk (*)
showing a note on the upper keyboard raised by a 50-cent diesis.
----------
EXAMPLE 3.
----------
<http://www.bestII.com/~mschulter/NIA003-337.mp3>
This example shows the use of the 337-cent small neutral third in a
progression where it contracts to a unison; the unstable sonority is
C-Eb*-G.
----------
EXAMPLE 4.
----------
<http://www.bestII.com/~mschulter/NIA004-791.1500.mp3>
An interesting feature of the theory of metastable or Nobly Intoned
intervals is that sometimes these zones can involve quite familiar
sizes, here a 791-cent minor sixth almost identical with the
Pythagorean 128:81 or rounded NI value (both 792 cents), and a minor
tenth at an even 1500 cents which approximates the NI value of 1503
cents. These intervals (G-Eb-Bb in either circle) expand to the octave
and 12th.
----------
EXAMPLE 5.
----------
<http://www.bestII.com/~mschulter/NIA005-287.422.mp3>
This standard neomedieval cadence uses a minor third at 287 cents,
slightly larger than the NI value of around 284 cents, with the NI
major third at around 422 cents between the middle and upper voices
(0-422-708 cents), a tuning found at Eb-Gb-Bb in either circle.
Here minor third contracts to unison and major third expands to
fifth.
----------
EXAMPLE 6.
----------
<http://www.bestII.com/~mschulter/NIA006a-287.422.longer.mp3>
This example has the same final cadence as the last, but approached
from the diminished seventh sonority D-F-Ab-Cb (0-313-587-888 cents)
available in either circle (compare 15:18:21:25, 0-316-583-884 cents).
The diminished seventh contracts to the outer fifth of a sonority with
a 4-3 suspension, the fourth resolving to a _minor_ third that then
resolves to a unison, as in the previous example.
----------
EXAMPLE 7.
----------
<http://www.bestII.com/~mschulter/NIA007-791.mp3>
This cadence uses the sonority G-Eb-B with its two almost identical
intervals of 791 cents (G-Eb) and 792 cents (Eb-B) in a kind of
Manneristic meantone idiom treating Eb-B as an augmented fifth.
The very slight inequality of these two intervals is a quirk of the
synthesizer temperament.
----------
EXAMPLE 8.
----------
<http://www.bestII.com/~mschulter/NIA008-946.mp3>
This neomedieval cadence features what I term in my new paper an
_interseptimal_ interval of around 946 cents, located in the
fascinated region between the septimal ratios of 12:7 (933 cents) for
a large major sixth and 7:4 (969 cents) for a small minor seventh.
Here it is coupled with another dynamic interseptimal interval at
around 454 cents, virtually identical to a just 13:10, in the region
between the septimal 9:7 major third at 435 cents and the narrow 21:16
fourth at 471 cents. In this context, these intervals (C*-F-Bb) serve
as an "ultramajor" third and sixth expanding to fifth and octave with
the upper voices rising by 50-cent steps.
The 454-cent interval showcased in this example, by the way, is almost
identical to Gene Ward Smith's "ratwolf" equal to precisely to 13:10,
also his name for a regular meantone temperament differing minutely
from 2/7-comma which produces a "RAT(ional) WOLF" at this just ratio
from a chain of 11 fifths up. In Zest-24, the 2/7-comma "near-ratwolf"
is tempered out or "domesticated" within each 12-note circle, but
happily "reintroduced into the wild" by the 50-cent diesis between the
two circles.
----------
EXAMPLE 9.
----------
<http://www.bestII.com/~mschulter/NIA009-926.mp3>
This Manneristic cadence in a meantone style uses a 926-cent major
sixth (or here diminished seventh) in the sonority C#-E-G-Bb at around
0-313-626-926 cents, followed by a 4-3 suspension and resolution.
-----------
EXAMPLE 10.
-----------
<http://www.bestII.com/~mschulter/NIA010-422.2113.mp3>
An interesting feature of metastable or NI intervals underscored in a
recent list contributed by David Keenan is that octave extensions can
make a difference. Here the metastable or NI major third at 422 cents
is coupled with a near-NI major 13th at 2113 cents, close to the
estimated NI zone at around 2109 cents. These intervals (Gb3-Bb3-Eb5
with C4 as middle C), available within either circle, resolve to fifth
and 15th (or double octave) respectively.
-----------
EXAMPLE 11.
-----------
<http://www.bestII.com/~mschulter/NIA011-2055.mp3>
Another example of an NI interval larger than octave, this cadence has
a 2055-cent neutral 13th, here used together with a 2752-cent neutral
third plus two octaves or neutral 17th (Ab2-E*4-B*4). These intervals
expand to the 15th or double octave and 19th or fifth plus double
octave. This wide a spacing of voices is rather rare in a neomedieval
style; but this example and the last show how certain NI intervals
well beyond the octave may provide an incentive.
-----------
EXAMPLE 12.
-----------
<http://www.bestII.com/~mschulter/NIA012-422.mp3>
This concluding example shows how the 422-cent NI major third may be
used as an idiomatic meantone diminished fourth in a Manneristic
style. Here we start at D-G-Bb-D, with the fourth and minor sixth
above the bass suggesting a cadential approach. The fourth G then
proceeds to the major third F# -- forming the diminished fourth F#-Bb
at 422 cents, which leads to a 4-3 suspension and resolution.

Sorry to trouble you! Certainly, and in fact I'm editing some output from Scala for this purpose, changing or adding a couple of interval names for the sixth and seventh steps of this 7-note set in the process, giving note names both in a line before the note (as in your example above) and also at the end of a line with the fraction and size in cents: E 0: 1/1 0.000 unison, perfect prime (E) F 1: 22/21 80.537 undecimal minor semitone (F) G 2: 33/28 284.447 undecimal minor third (G) A 3: 4/3 498.045 perfect fourth (A) B 4: 3/2 701.955 perfect fifth (B) C 5: 11/7 782.492 undecimal minor sixth (C) D 6: 39/22 991.165 tridecimal minor seventh (D) E 7: 2/1 1200.000 octave (E) The steps are around 81-204-214-204-81-209-209 cents.

On my chart the sets are in columns. If you look at the second column (second set), D is actually the fifth note.

Sorry I didn't see that part of your mail. Just to check, perhaps it is the way I wrote it, rather than what you are seeing being the problem. What you should see is 5 columns, with (sorry if untidy) dots filling up all the spaces (I did that the try to keep the spacing proper, as this site automatically deletes blank spaces!) So the left column is the letter-names of the pitches. Then you have 4 columns on the right, with the 7 notes of the scale, numbered. Really it is better to display it as a circle! For example First column 1=D, 2=D#-25c. Second column 1=G, 2=Ab-25, etc. If you can still not make sense of it, please let me know. Thanks! Justin

My players are able to perform best in cents notation, if only because it encompasses all manner of different tunings. There really is little difference between polymicrotonal tuning and 1200-tone equal temperament as I interpret it. For real time, seat of the pants playing, cents notation, with only two new symbols (quarterflat and quartersharp), deviations of 1-49 above or below any note are easily negotiated. New memorization of different symbols is perhaps better suite for electronic/keyboard based instruments, instruments with preset tuning as opposed to flexible tuning. Johnny [email protected] _ (mailto:[email protected] ) _jamsalinas _ (http://profiles.yahoo.com/jamsalinas) Mon Nov 12, 2007 8:03 pm (PST) I have just read this from the Sagittal notation doc.: We have also notated even higher divisions such as 270, 282, 306, 311, 342, 388, 494, 612, and beyond, as well as many below 224 I would love to see if you guys have done any progress in these higher divisions like 612 It sounds a very exciting work.

Yep, as it says there, we are indeed able to notate 612-ET with Sagittal (as well as many beyond that, up to 2460-ET). In fact, there's more than one way to do 612, but we haven't yet decided which should be the standard notation, which is why we haven't released anything specific. (Much the same could be said for the other divisions on that list.) Your question is very timely, because Dave Keenan and I have just finished defining all of the symbols that will be used for just intonation (which, in turn, will help us to determine how the above ET's should be notated). We expect to be releasing documentation very shortly regarding this, including a spreadsheet that will show how to notate (with alternate spellings) any ratio in Sagittal through prime limit 61 (using prime factor exponents, or "monzos"). > I would also love to hear Johnny's opinion about these symbols if > they get as accurate as his 1200edo notation. Since it's able to notate 2460-EDO, Sagittal is capable of roughly twice the precision, though it's debatable whether that's really necessary. For those don't want to cope with the many accidentals this requires, we offer lower-precision JI options: e.g., extreme- precision (olympian-level) JI corresponds to ~2460-EDO, whereas high- precision (herculean-level and promethean-level) JI is comparable to 612-EDO and 494-EDO (respectively), and medium-precision (athenian- level) JI to 224-EDO. If that's still too many accentals for you, then we would recommend mapping your tones to either 130-ET (using the spartan symbol set) or 72-ET (which uses less than half of the spartan set). > Do you think Johnny Reinhard, that this could improve the sight- > reading of your musicians if you had a chance > to teach them from scratch??? Johnny's notation is well suited to enabling players to arrive at the desired pitches on conventional flexible-pitch instruments. Sagittal is best suited to providing a meaningful notation for retuned fixed- pitch instruments, for specially built microtonal wind instruments, for the electronic medium, and for theoretical applications. The two approaches are quite different and are, in fact, complementary: each tends to excel in applications where the other is weakest. --George

Hmm ... first reading Johnny's answer to Tony, in which he describes his 1200-edo notation as employing all the regular accidentals, with additional quarterflat and quartersharp symbols, and 0-49 cent markings to indicate deviations from those ... and then George's description here of 2460-edo (minas), got me to thinking ... It's too bad that 2460 doesn't divide evenly into 24. The regular-plus-quartertone accidental set and deviation numbers 0-100 would make a nice reference tuning for the notation. Actually, Johnny, you don't even need the quatertone symbols for 1200-edo because you can just use the regular sharps and flats and +/-50 cents and still get precision to 1200-edo, if you can do without the enharmonic spellings of notes which would need the quartertone symbols. 2460-edo could theoretically be acheived in a similar way by using the regular sharps and flats plus numerical indications +/-102.5 degrees, so you can still get close enough for practical use by using +/-100. If the lowernote-plus-100 is not equal to uppernote-minus-100, so that there is one degree between those two values, then you get 201 degrees per 12-edo semitone, which is 2412-edo. You could also employ quartertone symbols to fit between these two values, without using any numerical deviations when using the quartertone symbols, in which case you get 202 degrees per semitone = 2424-edo. Anyway, just some ideas i had. The system Johnny already has in use feels very natural to a trained microtonal musician, because the quarter-tones are "anchors" at the 50-cent points, and so using +/-50 cents (without the quartertone accidentals) is an easy way for a performer to develop ear training to acheive the desired results. > For those don't want to cope with the many accidentals > this requires, we offer lower-precision JI options: > e.g., extreme-precision (olympian-level) JI corresponds > to ~2460-EDO, whereas high-precision (herculean-level > and promethean-level) JI is comparable to 612-EDO and > 494-EDO (respectively), and medium-precision (athenian- > level) JI to 224-EDO.

From: [email protected] (2007-11-13) Subject: Re: Saggital 612 or higher - & question for Johnny Hi Joe, Tony, George, Joe: Actually, Johnny, you don't even need the quatertone symbols for 1200-edo because you can just use the regular sharps and flats and +/-50 cents and still get precision to 1200-edo, if you can do without the enharmonic spellings of notes which would need the quartertone symbols. Johnny: Not ready to dump the tonal implications, some only psychological, of sharps to flats, that a more pure number approach would seem to be an improvement. The quartertone sharp and the quartertone flat are visual landmarks (not audible landmarks). They allow the conservatory trained music reader to follow a logic they come to expect as normal to playing. In addition, numbers 1-49 are clearly more likely to be numbers less than 25. 50 breaks the bank. Numbers larger than 50 are hard to negotiate on the hoof. I agree with George. Joe: Anyway, just some ideas i had. The system Johnny already has in use feels very natural to a trained microtonal musician, because the quarter-tones are "anchors" at the 50-cent points, Johnny: I think they are much more visual anchors for sight reading skill expectations more than they are soundposts for hearing an interval. Joe: and so using +/-50 cents (without the quartertone accidentals) is an easy way for a performer to develop ear training to acheive the desired results. Johnny: Sorry to pick (or poke), but where is the ear training from the following of visual symbology? They are apples and oranges here. The hearing of, and the initiating of, discrete microtonal intervals is independent of actually playing it. In fast movement the eye goes to a quartertone specific sector (quadrant?) and the deviation of a norm is quickly calculated. Even with this, I use a notation shorthand for quick fingerings, but I still need the number of cents to set the intellect of my mind. Both are necessary. But there is also a difference between genuine sight reading, and preparation preceding group reading. At a certain point, a player employs other symbology; I use a pair of glasses to make me alert at a certain point in a piece of music. I circle alternative fingerings to distinguish them from the much more usual fingerings(generally yielding monophonic pivots, if not simply alternative timbres). There are some fingerings for ease of motion, for trilling, for dynamic, for timbre, for pitch sensitivity (one with open tone holes and one with the gradual depression of a key). Of course, I know you know much of this. Joe: Myself, i still like 72-edo HEWM. ;-P I'm still looking forward to having HEWM and Sagittal notations in Tonescape someday, so i can compare the same piece notated both ways. -monz Johnny: Great art is made out of the material found about it. There are many ways to segregate. 72 does not yield just intervals that I miss. But I still think it is the composer that makes the difference, not the tuning. (But it does help some individuals over the hump of being derivative, the method that is so abundant taught in contemporary music education.) ************************************** See what's new at http://www.aol.com

Arigatogozaimas! Now I can read your chart without any problem Also, please let me thank you very warmly for the _Haru-no-Kyoku_ mp3, which sounds to me very often polyphonic, and sometimes seems to use what is called in Europe "imitation" -- that is, having the same melodic theme or pattern sounded first in one voice, and then in another. Your new listing of the four sets is very helpful in explaining a possible reason for the tuning I have proposed. However, please let me emphasize that _it is not necessarily better than your tuning above, or Herman's_. Either of those might be better, and also closer to the prevailing practice as you have described it! Herman, please feel warmly welcome to step in at any point. I suspect that we are illustrating two approaches to tuning, and I hope that I am correctly interpretating your intentions. As I emphasize below, your tunings of minor thirds and sevenths are just as good as mine, and my idea is to experiment with the idea of a single chain of nine fifths to express the four transposition sets -- six pure fifths and three tempered by a tad less than five cents. A possible advantage of my tuning is that it could be done on certain instruments with fewer than 13 notes available per octave, since it would allow us to use a single string, flute hole, or key on a keyboard to represent what have traditionally been two separate pitches. Thus we have in the usual style C# and C#-25, D# and D#-25, and F and F-25. Here I would prefer to spell C# as Db, since C to Db-25 in the 4th set is a usual semitone, and Db-25 to Ab-25 is a regular fifth. However, I understand that Western note spellings may sometimes be confusing, and might actually myself be quite happy simply to use cents. Why don't I first show my ten-note tuning in which we would need only one version rather than two for Db, F, and Ab; and then the four sets as they would be played in this tuning. Here I would add the Western note names at the end of each line, not being sure if they are helpful, and also column listing of where the note appears in each set, with an "n" meaning it is not used in a given set. For example, the notation "D:154n" tells us that D is the first step of the 1st set, the fifth step of the 2nd, the fourth step of the 3rd, and is not used in the 4th. I've tried to get the four columns to line up. 0: 1/1 0.000 unison, perfect prime (D:;154n) 1: 22/21 80.537 undecimal minor semitone (Eb:26n3) 2: 9/8 203.910 major whole tone (E:;nn5n) 3: 33/28 284.447 undecimal minor third (F:;3764) 4: 4/3 498.045 perfect fourth (G::4175) 5: 88/63 578.582 (Ab:n2n6) 6: 3/2 701.955 perfect fifth (A::5n1n) 7: 11/7 782.492 undecimal minor sixth (Bb:6327) 8: 39/22 991.165 tridecimal minor seventh (C:;7431) 9: 13/7 1071.702 16/3-tone (Db:nnn2) 10: 2/1 1200.000 octave (D:;154n) We may need to discuss some concepts a bit, if you are curious, because I realize that the theory can get rather complicated. However, the basic idea is that if we'd like a note to be in two different places in different sets, maybe we can put it somewhere between those two places, and then leave it where it is for both sets. This is a compromise, and if you find that it's better just to move that note as convenient, then you would not be wrong! Maybe the best way to start explaining is to see how each of the four sets will be tuned with this scale of only ten notes in the octave. Here I will keep the original numbers of the ten notes for each set. 1st set 0: 1/1 0.000 unison, perfect prime (D:;154n) 1: 22/21 80.537 undecimal minor semitone (Eb:26n3) 3: 33/28 284.447 undecimal minor third (F:;3764) 4: 4/3 498.045 perfect fourth (G::4175) 6: 3/2 701.955 perfect fifth (A::5n1n) 7: 11/7 782.492 undecimal minor sixth (Bb:6327) 8: 39/22 991.165 tridecimal minor seventh (C:;7431) 10: 2/1 1200.000 octave (D:;154n) 2nd set 4: 1/1 0.000 unison, perfect prime (G) 5: 22/21 80.537 undecimal minor semitone (Ab) 7: 33/28 284.447 undecimal minor third (Bb) 8: 117/88 493.120 fourth narrow by 4.925 cents (C) 10: 3/2 701.955 perfect fifth (D) 1: 11/7 782.492 undecimal minor sixth (Eb) 3: 99/56 986.402 undecimal minor seventh (F) 4: 2/1 1200.000 octave (G) 3rd set 6: 1/1 0.000 unison, perfect prime (A) 7: 22/21 80.537 undecimal minor semitone (Bb) 8: 13/11 289.210 tridecimal minor third (C) 0: 4/3 498.045 perfect fourth (D) 2: 3/2 701.955 perfect fifth (E) 3: 11/7 782.492 undecimal minor sixth (F) 4: 16/9 996.090 Pythagorean minor seventh (G) 6: 2/1 1200.000 octave (A) 4th set 8: 1/1 0.000 unison, perfect prime (C) 9: 22/21 80.537 undecimal minor semitone (Db) 1: 968/819 289.372 (Eb) 3: 121/91 493.282 (F) 4: 176/117 706.880 (G) 5: 3872/2457 787.417 (Ab) 7: 484/273 991.327 (Bb) 8: 2/1 1200.000 octave (C) The secret is that we are using only a single chain of fifths for the whole tuning, nine fifths in all to give our ten notes per octave. Six of these fifths are pure, as in Herman's tuning also, where three of them are made wide by about five cents each. Note that the tunings vary a little from set to set, but that they should all be reasonably tolerable, if my guess is correct -- this is for you to judge! Indeed many of the intervals will be identical to those of Herman's fine tuning. Thus note that the 1st and 3rd sets have a pure fifth and a pure fourth above the first note (D or A), and that in the 3rd set, from A to G is a Pythagorean minor seventh at 16:9 or 996 cents. At the same time, melodically, you will see that the semitone steps in each of these four sets, found between the first and second steps of a given set and also the fifth and sixth steps, are about 81 cents, somewhat wider than the preferred 75 cents, but yet smaller than the 90 cents we would get tuning with all fifths and fourths pure. This brings me to the idea of a "chain of fifths," which you also mentioned in a message with questions for Herman. I will try and show the chain of fifths in this tuning, starting with Db and going to E. Db--+4.9--Ab--0--Eb--0--Bb--0--F--+4.8--C--+4.9--G--0--D--0--A--0--E Here a "0" between two numbers means a pure fifth, and "+4.9" or "+4.8" shows that a fifth is tempered wide by about 4.9 or 4.8 cents. > Could you tell me why you prefer "33/28 284.447 undecimal minor > third" to Herman's suggestion "32/27 294.135 Pythagorean minor > third"? Actually I think that these are both fine minor thirds, and very much like both flavors or shadings, as they might be called. The possible advantage of 33:28 is that, as one pleasing kind of minor third, it might be closer to a pure fourth in relation to your preferred size of minor sixth around 775 cents -- or, here, often 782 or 787 cents. Actually, 284 is closer to a pure fourth below 782 cents, while either 284 or 294 cents (32:27) is comparably close to a pure fourth below 787 cents. > And "39/22 991.165 tridecimal minor seventh" to Herman's suggestion > "16/9 996.090 Pythagorean minor seventh"? Either of these minor sevenths is fine! I'd be happy to use either. In fact, if you are playing polyphony and play a note, its fourth, and minor seventh all together -- about 0-498-996 cents -- then you might prefer the pure 16:9 minor seventh of Herman's tuning, because both fourths will be pure. With my version, if you play D-G-C in the first set at the same time, D-G will be a pure fourth, but G-C will be almost five cents narrow. I use this kind of sound often, but you would not be wrong to prefer pure intervals. What I may need to explain in a more careful and step-by-step way is how a chain of fifths, or more than one chain, can be used to built a tuning. The idea of my tuning is to have as many reasonably useful fifths and possible with the smallest number of notes per octave; have most of these fifths and fourths pure; and have scale steps like the second and sixth in a given set fairly close to their usual sizes as you have described them.

Dear Oz and Dave, Please let me diplomatically attempt here to mediate in a situation which I suspect must occur many times in the realm of musical practice and theory. Oz, you have used a mathematical formula which Dave devised and he and I documented for rather different purposes -- but to excellent effect, deriving a fine size of small neutral second for maqam music. The step of 131.55 cents should be especially welcome to Persian or Kurdish ears, for example, attuned to maqam or dastgah styles where a step on the order of 14:13 is very idiomatic. Here the mathematical noble mediant between 14:13 and 27:25 -- or also 1:1 and 13:12, as Dave has suggested -- happens to yield a fine melodic effect. I see no reason not to use this mathematical formula, or any mathematical formula, when it produces a result that fits the musical situation. Dave, you are equally correct that the concept of Noble Intonation was, if I am correct, conceived as especially applying to _simultaneous_ intervals which represent regions of maximum complexity between two simpler ratios. A classic illustration, of course, is the pair of major thirds at a just 5:4 and 9:7, with the NI region located somewhere around 422 cents. Thus I warmly agree that it would be a misunderstanding of the original NI concept to think that _any_ mathematical noble mediant between a pair of integer ratios will produce an audible "NI" effect. In fact, Oz's purpose seems to me quite different: to strike a kind of artful compromise between two sizes for _melodic_ steps, 14:13 and 27:25. The mathematical noble mediant operation happens to produce a most agreeable result -- although that wasn't its original purpose. Dave, I would say that one of the hallmarks of really great concepts and discoveries is that they may be used in various ways. Sometimes applications not anticipated by the discoverer may arise -- for better or worse -- and even be (mis)attributed to the discoverer. Here I would say, "Oz -- congratulations on a fine maqam tuning!"; and to Dave, "Indeed, while the formula was used here to pleasant effect, people should understand that the NI concept which gave rise to the formula is somewhat different." With warmest wishes to you both, and all, Margo Schulter [email protected]

[And then he played > the Biber unaccompanied Passacaglia, and then we went on to the > Corelli as I mentioned above.] Hi, Brad. Indeed this is a very interesting period, for me more or less _ultra_-modern, and in one style of periodization we would say that the 1640's might mark the end of the Manneristic era (1540-1640 or so) and the beginning of the Early Baroque. In another traditional approach, the Baroque starts around 1600 with the rise of continuo notation, opera, and oratorio, so the whole 17th century would be included. One small point, where I know that usages differ, although maybe not so relevantly for the intonational questions we're considering: While it's common to apply major/minor key labels to early 17th-century music, I might prefer to follow the composer's designation, whatever it is, for example a given tone or mode. Of course, if composers are already using major/minor terminology, then that would be both appropriate and very noteworthy -- for Uccellini, I'm not sure. > Again: what would you have us do? 1/4 comma meantone doesn't really > work for *any* of these pieces, unless we're supposed to put up with > ridiculous-sounding B major and F# major in normal cadencing > situations. Actually my guess is that 1/4-comma meantone should be just fine, if you use a tuning set which has accidentals with proper spellings for sonorities like B-D#-F# and F#-A#-C#. This would often involve the very authentic period choice of an instrument with more than 12 notes per octave. While an instrument with only a couple of split keys (G#/Ab, Eb/D#) would address a lot of common situations, here we also need A#, which might suggest an instrument with at least 17 notes per octave. A usual _cembalo cromatico_ of the kind popular around Naples in the epoch of Gesualdo, with 19 notes per octave likely tuned in 1/4-comma, would neatly address the situation. This is the kind of 19-note keyboard recommended by Praetorius, and also taken by Fabio Colonna (1618) as the basis for tuning the first 19 notes of his 31 note _Sambuca Lincea_ evidently based on a cycle of 1/4-comma meantone closely approximating 31-EDO. Of course, Colonna is championing a 31-note meantone cycle which goes back to Nicola Vicentino (1555, 1561). In 1666, Lemme Rossi discusses both extended 1/4-comma meantone and a precise 31-EDO, with Christiaan Huygens in 1691 advocating "The New Harmonic Cycle" based on 31-EDO, which he also shows differs only minutely from the familiar 1/4-comma. Of course, one could construct examples where extended 1/4-comma (or 31-EDO) would run into problems: specifically, if a composer relies on enharmonic equivalence, as Vincenzo Galilei does in the late 16th century specifically to show the "perfection" of 12-EDO and the lute as an instrument customarily using it. However, unless this kind of equivalence is demanded, my guess is that the problem you are describing is not inherent to 1/4-comma, but rather to instruments which don't cover a large enough range of it to have available the needed accidentals for a given piece. I realize, of course, that this is a rather obvious point; but since period practices are such an important consideration in this thread, maybe mentioning split-key accidentals isn't out of place. This leaves the question, "What should we do if only a 12-note keyboard is available?" That's an intriguing question. Of course, one period solution (however controversial) is a regular tuning at or not too far from 12-EDO, which Mersenne discusses in the 1630's, and Denis heartily disapproves in his treatise on keyboard tuning and music (1643, 1650). Doni tells the story that Frescobaldi recommended 12-EDO for a new church organ which Doni persuaded those responsible to tune in the usual meantone -- however accurate or otherwise this tale. Another is some kind of temperament ordinaire based on something around 1/4-comma. An interesting question is what context F#-A#-C# appears in. If it's used as a cadential sonority leading to B, then a bit of ornamentation might help (a la Schlick 1511). Mark Lindley suggests that even an unaltered 1/4-comma diminished fourth at 32:25 (427 cents) might be used in ornamented contexts, although an irregular scheme that ameliorates F#-A# to about Pythagorean could further ease this dilemma. Again, 1650 is really late for me, so I'd welcome comments from Tom or others more conversant with this epoch. Most appreciatively, Margo Schulter [email protected]

In the Uccellini piece we played, it had me sitting on B major for a whole bar at a time while the violin played melodic/ornamental stuff, and then E minor for the whole next bar. This happened several times. Sure, I could have made up more ornamental stuff of my own during some of that, and I probably did, but there's also the danger of competing too much with the melodic part. And if I would have had to do it every time there's a whole bar that is sounding cruddy, just because a bad temperament has been set up...well, that's just not a very good musical reason for that much ornamentation (in my opinion). The ornamentation itself would have had so many wrong enharmonics in it (if forced to use a 1/4 comma system), it would just be a mess. Similarly, as I mentioned, the Corelli D major sonata we played (from 1700) had a bunch of F# major and C# major in it. Some sections modulated into G# minor, as well. And, in that sonata, the harpsichord or organ had to play those harmonies for a whole bar (with a somewhat moving bass line, too), in long sequences, while the violin did bariolage figurations in continuous motion: four-note chords of his own, broken up. Again, not a great place to try to make up right-hand dodgy continuo stuff just because an F would be way too high to serve as E#, or a Bb way too high to be A#. The far more elegant solution is to scrap the unworkable notion of 1/4 comma around the naturals, open the thing up, and have some room to breathe! I don't see any compelling reason to borrow advice from Schlick 1511 to play music from more than 130 years later (the Uccellini and Schmelzer), or 189 years (the Corelli)! :) ===== To try out the new Yale University organ a few months ago (while it was still inside the factory in Virginia), I brought along a book of Froberger. The instrument has regular 1/4 comma everywhere, and several split keys for the subsemitones (two or three splits in each octave, except for the bass). Well...it still didn't work. I tried out several pieces that were harmonically adventurous, from the 1640s-60s. And they just sounded stupid whenever notes such as E# and B# turned up, having no split key available. No amount of ornamentation salvaged such spots, especially in a piece by Froberger that *ends* each of its sections on a C# major triad! Nor do I buy the fantasy argument that organists simply transposed the whole piece (if indeed they played composed pieces in public at all...); one of the Froberger toccatas I played needed not only E#/A#/D#/G#/C#/F#, but also Db/Ab/Eb/Bb and F and C. And it's definitely an organ piece: by its title, it's for use during the elevation of the host during a liturgy. There's no wholesale transposition of the composition available that would get it to work on extended regular 1/4 comma, even if all five raised keys got split...because it would also have to have one or more split *naturals*. The failure here is not the physical keyboard with its limitations, but rather the premise of 1/4 comma for such repertoire. I find it sad to see a brand-new, deluxe, expensive organ go into service, with a temperament scheme unable to play early-to-mid-17th-century core repertoire. (Some Frescobaldi would have problems, too.) But, they built it the way the customer wanted and ordered it.... Brad Lehman

This happened several times. Hi, Brad. Please let me agree that in this kind of situation, ornamentation isn't such a good solution: assuming that D# and Eb both occur, I'd say that a likely period solution would be either a split-key instrument with both accidentals, or a continuo instrument like a lute with approximately equal semitones where D# and Eb would be equivalent. The 17-note organ you describe below would solve this kind of situation admirably, although, as described below, I would have urged them to add E# and B# as well for a standard 19-note tuning (Gb-B#) of the kind very popular in areas like Naples around 1600. > Sure, I could have made up more ornamental stuff of my own during > some of that, and I probably did, but there's also the danger of > competing too much with the melodic part.

Friendly amendment: "if forced to use a 1/4-comma system with an insufficient accidental range to accommodate the piece." This isn't to say, of course, that because one _could_ play Bach in a 31-note circle of 1/4-comma or 31-EDO, therefore one _should_: we likely agree that a 12-note well-temperament is much more idiomatic. I'd say that your interpretation of the 1722 diagram is one very interesting contender, with some Neidhardt temperaments also very plausible. However, I should caution that I feel on much more confident ground when discussing modal rather than tonal styles. > Similarly, as I mentioned, the Corelli D major sonata we played > (from 1700) had a bunch of F# major and C# major in it.

Since Corelli's style is often regarded as the clear advent of major/minor tonality, I'd say that there could be arguments for a temperament less heavy that 1/4-comma on melodic grounds; we might want a narrower diatonic semitone narrower than 117 cents, for example. Around 1700, there's evidence that people often preferred something around 1/5-1/6 comma, not to speak of various irregular schemes. However, a strictly technical answer to your remarks is that a 19-note tuning of 1/4-comma (Gb-B#), the kind of thing that had been known for at least about 150 years by 1700, would provide both A# and E#, as well as B# if that should come up. Again, I'm not saying that it's the best temperament for repertory around 1700, only that from a view of having the right accidentals, it allows considerable "room to breathe." > I don't see any compelling reason to borrow advice from Schlick > 1511 to play music from more than 130 years later (the Uccellini > and Schmelzer), or 189 years (the Corelli)! :) While it was my purpose to honor Schlick for his description of what might be called the first known modified meantone tuning, I should emphasize that for music around 1650, there are some later clues and theorists that suggest similar conclusions. Thus Praetorius in 1618 or so reports that some people tune 1/4-comma so as to compromise notes such as G#/Ab -- much, I would add, as Schlick describes in 1511. Also, Werckmeister in his _Orgel Probe_ of 1698 urges people who want to stick with the "Praetorian temperament" (i.e. 1/4-comma) to consider at least doing precisely this kind of thing with Eb/D#, for example. I'm not recommending it as an ideal solution, but mentioning it as an idea that comes up in 1618 and 1698 as well as in 1511. As to the use of a major third around Pythagorean -- or possibly even a full meantone diminished fourth -- in an ornamented cadence, Mark Lindley suggests indications in some keyboard music around 1600 where D# is consistently treated in this way as evidence for a regular meantone in 12 notes (e.g. Eb-G#) with this liberty allowed. Again, this is very much like Schlick's treatment of G# in his organ compositions. This isn't to say it is an ideal, or even credible, solution for every mid-17th century piece as played on a 12-note instrument in a more or less regular meantone around 1/4-comma, only that I'm not relying on Schlick in isolation to raise certain possibilities that _might_ be tried for some pieces. Also, I'd emphasize that some 16th-century as well as 17th-century pieces clearly call for a proper D#; Vicentino uses it, as does Andrea Gabrieli in a musical setting of the Oedipus drama where trying to ornament every time it comes up would be quite untenable. Of course, if the range happens to stay within Bb-D#, then on harpsichord one could retune Eb to D#, and then retune it for pieces preferring the more usual Eb. The Yale University organ, of course, would make such retuning unnecessary, since it has both Eb and D#. > To try out the new Yale University organ a few months ago (while it > was still inside the factory in Virginia), I brought along a book > of Froberger.

My first reaction is that I would have advised them, if they're going this far, to go just a bit further and have a standard 19-note tuning of Gb-B#, which, for example, very nicely supports C#-E#-G#. The main reason wouldn't necessarily be to play Froberger, whose music Mark Lindley suggests is really best in 12-EDO, but to fit the style of composers like Gesualdo and Trabaci who may use a range of Gb-B#, and make a distinction, for example, between B# and C at a diesis apart (I know specifically that Gesualdo does this). This would be like the lower manual of Nicola Vicentino's arcicembalo or (presumably) arciorgano, with 19 notes (also Gb-B#). There is a theoretical consideration supporting this tuning size, standard on the _cembalo cromatico_ around 1600 and also on some French instruments like that of Costeley (which he started using in 1558, as I recall, and described in 1570) at 1/3-comma or 19-EDO. We have what Erv Wilson calls in modern terms a "Moment of Symmetry" (MOS) where there are only two sizes of adjacent steps, here the meantone chromatic or minor semitone at about 76 cents in 1/4-comma, and the enharmonic diesis at 128:125 or about 41 cents. Here's a Scala file: ! meanquar_19.scl ! 19 of 1/4-comma meantone scale 19 ! 76.04900 117.10786 193.15686 269.20586 310.26471 5/4 462.36271 503.42157 579.47057 620.52943 696.57843 25/16 8/5 889.73529 965.78428 1006.84314 1082.89214 125/64 2/1 However, I certainly wouldn't be disappointed with that 17-note Gb-A# instrument (which would be an MOS in a Pythagorean tuning, or some modern regular temperament with fifths a bit larger than pure, obviously both relevant to other styles than those we're discussing!). There's a wealth of conventional and more adventurous 16th-century and early 17th-century music that will fit beautifully on that new organ, including, of course, pieces with both Eb and D#, or indeed chromatic settings by Lasso that go up to A#. While there might be a few pieces by Frescobaldi that might not fit, there are lots and lots that will. Also, where diminished fourths or augmented fifths are intended as "special effects" intervals in meantone, they'll have their characteristic proportions. Having stated some advantages of 19 tones above, I should emphasize that split-key instruments varied considerably in the number of notes per octave, with 17 as one quite tenable compromise. The repertory is large enough that the new Yale instrument should make lots of beautiful music. > Nor do I buy the fantasy argument that organists simply transposed > the whole piece (if indeed they played composed pieces in public at > all...); one of the Froberger toccatas I played needed not only > E#/A#/D#/G#/C#/F#, but also Db/Ab/Eb/Bb and F and C.

First of all, Lindley's suggestion of 12-EDO as Froberger's preferred tuning would cover this kind of situation; it's an interesting question whether, if Lindley's conclusion is correct, this might be indirect evidence that Froberger was influenced in this taste by his teacher Frescobaldi, maybe making Doni's story about the latter's penchant for 12-EDO more credible. Then, again, the example of Zarlino and his student Vincenzo Galilei cautions us that a teacher is not necessarily responsible for all the views of her/his pupil -- although Galilei, as it happens, expresses a liking for Zarlino's 2/7-comma as the most pleasing keyboard temperament. As I explained above, the "split naturals" as you call them of E#/F and B#/C are standard in a 19-note meantone tuning of Gb-B#, which is what was tuned in parts of France and Italy around 1600, and also specifically commended by Praetorius in 1618 as solving lots of accidental problems. With "an extended regular 1/4-comma" in this size, no transposition would be needed, because all of your accidentals specified above would be available in their usual places. Just for fun, I would add that if your listing of accidentals for the Froberger toccata is complete (Db-E#), one _could_ play this on a 17-note Gb-A# instrument by transposing down a fifth or up a fourth. Then we would have Gb-A#, which just fits the range of the instrument. This isn't to say that this fantasy scenario, as you term it, is an ideal solution: if Froberger intended 12-EDO, I'd say that that is what we should use, a fascinating early instance of its choice for an organ piece. However, if the folks at Yale want to try a transposition as an interesting kind of variant reading, I'd say, "Go ahead, and let's hear how it sounds." This is the same kind of thing that applies to Aaron Johnson's meantone realizations of Elizabethan and Jacobean keyboard music, where 1/3-comma or 19-EDO might be a bit heavier temperament than Bull might have used, but is quite pleasing and striking. > The failure here is not the physical keyboard with its limitations, > but rather the premise of 1/4 comma for such repertoire.

(Some Frescobaldi would have problems, too.) But, > they built it the way the customer wanted and ordered it.... Personally, I find it delightful to see a brand new organ go into service with a temperament scheme ideally fitting a vast repertory of 16th-century and early 17th-century music -- much of it within a conventional Eb-G# range, and some of it calling for 13-17 notes per octave. Here I'm talking about the Renaissance and Manneristic eras, say 1450-1650 or so. The fact that a few pieces might not fit, or technically might be playable but really better adapted to other tuning schemes, should hardly be cause for sadness, only an indication that no one tuning scheme can cover everything. Yes, 19 notes would have been yet more versatile than 17, and 31 notes more versatile yet (a complete 1/4-comma circle) -- but the perfect need not preclude the very good. Also, I'm not offering 1/4-comma as a universal temperament solution. The people at Yale might also want a Pythagorean organ for medieval repertory (17 notes, Gb-A#, as described in the early 15th century, would be ideal), and something in a irregular 12-note temperament of some kind if they're going to play music after around 1650, or also a few earlier pieces you've mentioned that might fit this kind of scheme.

It has "two or three splits in each octave" (maybe I could have said that in a clearer way: 14 or 15 notes in the octave). Its spec is here: http://www.taylorandboody.com/opuses/opus_55_pages/opus_55_finished_a. html Close-up photos of its keyboards: http://www.taylorandboody.com/opuses/opus_55_pages/10_19_06/55keys.htm http://www.taylorandboody.com/opuses/opus_55_pages/7_22_06/55sharps.ht m http://www.taylorandboody.com/opuses/opus_55_pages/11_09_06/55_keyboar ds_finished.htm And no transposition of the Froberger toccata I brought in would work on it.

From: Margo Schulter (2007-11-23) Subject: Re: continuo with keyboard meantones, continued Dear Brad, Please let me quickly try to reply to your clarification about the organ. I'd like to express my regrets for any needless controversy or excitement in my remarks, especially when I have a responsibility to set a different kind of example on this list, as some of your writings very wisely remind me. First, while trying to follow the information offered by the builder of the Yale University organ still left me uncertain to exactly how many subsemitones or split-key accidentals there are in an octave, your estimate of 14 or 15 sounds very reasonable -- maybe G#/Ab, Eb/D#, plus one other pair (C#/Db?). If I now understand correctly, then obviously we're agreed that lots of music likely intended for other kinds of tuning systems will be out of its reach, as well as some 19-tone meantone repertory like the _cembalo cromatico_ music around 1600 or some Gesualdo pieces. However, this is hardly in my view a major fault of the Yale organ, because I'd regard even a usual 12-note keyboard in 1/4-comma meantone as incredibly versatile. In fact, I'd say that Eb/D# and G#/Ab should handle a lot of commonly occurring situations around 1600. If I were advising them, I would say that considering 19 notes per octave would be good (Gb-A#). What I'd _really_ like to see is a 31-note instrument, which shows the full potential of 1/4-comma and supports enharmonic or fifthtone pieces (e.g. Vicentino and Colonna). Especially in a group which often celebrates explicitly microtonal music, I consider this well worth mentioning. Having said this, I'd like to focus on a few important points which could be more important than technical niceties of transposition and the like. First, I'm really not in a good position to give opinions on what is best for Froberger, Corelli, or Bach. This music is outside the scope of what I'm familiar with and take as the main basis for my own compositions and improvisations. Having seen what happens when people discuss medieval and Renaissance music, often in widely disseminated articles or textbooks, with what seems to me less than comfortable familiarity with these styles, I have no reason to suppose that I would do better with periods likewise not so familiar to me. Further, I don't have the justification many of these authors do that "the curriculum requires it." Thus I should enact a self-denying ordinance excluding myself from the "Bach's tuning" debate; people who are well-informed can get themselves into enough dilemmas without my "help"! Further, I would emphasize that a temperament like Zest-12 or Zest-24 is _not_ proposed as an "historical tuning" of any kind, but rather a 21st-century tuning that happens to fit certain stylistic directions. Specifically, having mentioned some possible "compromises" in our discussion, I would emphasize that I _don't_ consider ornamented versions of standard 16th-17th century cadences as the best use for a major third of 408 cents or 422 cents, say. A far nobler use is to use such a third so that it will really be in tune, whether as a meantone diminished fourth, or as a usual neomedieval major third. Thus in Zest-12 or Zest-24, B-D# is much nicer in some kind of neo-Gothic context (e.g. B-D#-G# before A#-E#-A# or A-E-A) than in B-D#-F# before E-G#-B. Likewise, F#-A#-C# is beautiful in a 13th-century style of cadence to G#-D#. The sad thing about meantones, and especially some modified ones, from a certain 21st-century perspective, is that you have all of these wonderful wide major and small minor thirds that didn't really get fully used in 16th-17th century period styles, because people weren't aware of how nicely these intervals might fit more of a 13th-14th century style. Anyway, without taking any position on the Bach tuning question, I must admire and commend your thoroughness in testing out different pieces and seeking a solution "to taste" that can also fit the historical evidence. That is a great contribution. With many thanks, Margo

Take another look at the photo links I sent, especially this one: http://www.taylorandboody.com/opuses/opus_55_pages/10_19_06/55keys.htm 1. Speaking first about the notes above tenor c: All of the Eb/D# are split. Most of the G#/Ab are split, but not all of them. A few of the Bb/A# are split, but it's less than half of them on the instrument. No other splits. No Db, Gb, Cb, B#, or E# anywhere on the instrument. If I remember correctly, from only about 20 minutes of playing it some months ago, the Eb/D# and the G#/Ab play differently from each other: the front half of the key plays the Eb or G# (i.e. the more frequently-needed note), and the back half plays the D# or Ab. It would have made more sense to me as a player to have the back half always be the flat and the front half always be the sharp, or vice versa, consistently across the whole keyboard.... The actual layout makes it quite tricky to play things such as A-flat major triads, using the front half of one split key with the back half of the other one. 2. Now to the bass octave, everything below tenor c: No subsemitones anywhere (not even for the G#/Ab); rather, all the split keys there (but only available on one of the three manuals) are to handle the short-octave layout. That lowest octave is short, whether the keys are split or not: the lever looking like "E" plays C, the F plays F, the "F#" plays D, the G plays G, the "G#" plays E, the A plays A, and then the Bb and B do what they look like. The low F# and G# are available only on the lowest manual, the Ruckpositif, by playing the back half of the split. On the other two manuals those notes aren't available. Lowest C# or Eb aren't available on any of the manuals. Compositions requiring them *won't* be played. 3. And in the pedal it's fully chromatic, except that there's no lowest C# or Db. Or any subsemitones (unless I'm mis-remembering the pedalboard). It seems to me, if Yale's folks wanted their organ students to learn short-octave layouts and 1/4 comma meantone hands-on and intimately, another good way to do so would be to have all their organ students take at least a required year of harpsichord lessons, and give them harpsichord tuning duties, on some suitable early-Italian or early- German harpsichords. :) Short-octave stuff is daily bread, with a couple of different schemes, for some of the harpsichord repertoire by 17th century Germans (and Froberger)...and especially so, going back into the 16th in other countries as well. I must also say, not in conjunction with Yale or anything else specifically, but just to say it: the presence of split keys and/or short octave on any keyboard instrument still doesn't constrain anybody to use regular 1/4 on it, to the exclusion of other systems. What's to stop anyone from tuning a subsemitones keyboard to regular 1/6 or anything else of one's fancy? (And the front half and the back half would then be one Pyth comma apart....) The split keys only provide an option to do some *different* note, and to have either half be the higher-pitched half, to one's choosing. On an organ, though, such things can't be changed day to day.

I have been unwell this week, that is why my response is delayed. I tried so long in vain to search for a temperament which could replace 53-equal, with two middle seconds (12:11 and 13:12 respectively) and with strong 7-limit flavours. Other than 46-equal, I could locate only 34-equal with a single 3/4 tone and minimal number of tones to work for maqam music. I have aligned the frets of my bowed tanbur to 34 and appreciate very much the results. Seeing as 34-equal is sort of an NI temperament, and is the minimal tuning which would work for maqam music, I think it will do for a new theory of maqamat. Now, the issue is, whether we can have an acoustical piano which accomodates 34-equal. The black keys are easy enough if split in two for 17-equal. But I wonder what can be done to switch between the bikechains of 17-equal on the fly.

What I suspect, Brad, is that this question of preference might be one indication of what repertories a given player is most familiar with or gives highest priority. You are, of course, correct that Ab-C-Eb or the like would be easier if flats were aligned with flats, and sharps with sharps, consistently. My own preference would be for the rather standard 16th-century approach they've evidently taken, which is also Vicentino's, for example. I would regard Eb and G# as "usual," and D# or Ab as more "unusual." While I haven't experienced this issue directly with split keys proper, I have dealt with the analogous situation of mapping a 17-note circulating system to a potentially 24-note keyboard with two standard 12-note manuals. Do I put all the flats on one keyboard and the sharps on another, or do Eb-G# on the lower keyboard and the more "unusual" accidentals on the other? I've tried both, and preferred the Eb-G# arrangement as more familiar, although it is much _less_ convenient for Ab-Eb, especially if this occurs with an octave, Ab-Eb-Ab -- and likewise with G#-D#. Well, with a 17-note circle, at least there's the compensation of having the fifth A#-Gb (or A#-E# for an equivalent spelling) with both notes on the same keyboard. Actually, with two 12-note manuals, I find that I tend to go for 24-note tunings where the two manuals have identical steps and intervals at some fixed distance apart (e.g. 1/4-comma or 2/7-comma meantone at the enharmonic diesis, or Zest-24, a kind of modified variation on the latter, with 18 or the 24 notes identical to a regular 24-note tuning). > I must also say, not in conjunction with Yale or anything else > specifically, but just to say it: the presence of split keys and/or > short octave on any keyboard instrument still doesn't constrain > anybody to use regular 1/4 on it, to the exclusion of other > systems.

On > an organ, though, such things can't be changed day to day. Please let me enthusiastically second this very important point, which indeed might easily get overlooked among the specifics of a discussion about the Yale organ. Interestingly, one historical tuning that very much comes to mind shares with your 1/6-comma example a set of split accidentals at Pythagorean comma apart: a 17-note Pythagorean tuning (Gb-A#) of the kind advocated by Prosdocimus de Beldemando and Ugolino or Orvieto in the earlier 15th century. A keyboard supporting this 15th-century tuning scheme -- Lindley isn't sure if it might have been implemented at that time -- would also nicely support a modern 17-note circle, equal or unequal (as with George Secor's 17-WT). Or, of course, it could support 17 notes of any desired meantone temperament. Again, I've had experience only with a crude equivalent of real split keys: tuning certain keys on two 12-note MIDI keyboards to different notes, e.g. C# on the lower keyboard and Db on the upper, or F and E#, etc. I'd suspect that even with the Ab-C-Eb complication you describe (if my curious preference for Eb and G# at the front is followed), actual split keys might be a bit easier than having to find the notes for such a sonority on two different manuals -- a good finger-stretching exercise, as I've reminded myself trying it a moment ago. Best, Margo
From: Margo Schulter (2007-11-25) Subject: Re: Two 31-equals spaced 15.42 cents apart so as to achieve an NI interv Dear Ozan, Please let me thank you for your mention of 17-EDO and 34-EDO. This reminds me of a 34-note system I proposed some years ago, and which looks very interesting for maqam music -- as long as you can do without ratios of 5. The system uses two complete circles or "bicycle chains" of 17-EDO at about 55.106 cents apart. ! 17x2_55.scl ! Two complete 17-tET chains spaced for pure 7:6 (~55.106 cents) 34 ! 55.10620 70.58824 125.69444 141.17647 196.28267 211.76471 7/6 282.35294 337.45914 352.94118 408.04738 423.52941 478.63561 494.11765 549.22385 564.70588 619.81208 635.29412 690.40032 705.88235 760.98855 776.47059 831.57679 847.05882 902.16502 917.64706 972.75326 988.23529 1043.34149 1058.82353 1113.92973 1129.41176 1184.51796 2/1 Note that there quite reasonable approximations of septimal flavors (including some pure 7:6 thirds), and also of 14:13 and 13:12. The large neutral second at around 156 cents is rather larger than 12:11; but there are nice approximations of 11:8 and 16:11, with the 55-cent interval between the two chains rather close to 33:32. For Persian or Kurdish music, the 126-cent step should be quite pleasing, and also the small 337-cent neutral third (near 243:200), which is not far from the NI size of around 339 cents. Of course, as you note, the 424-cent major third of 17-EDO is very close to NI. An interesting touch is that we get a minor third size very close to 19:16, formed by the larger neutral second steps of 141 and 156 cents. This is quite close to the 64:59:54 division mentioned in some medieval Islamic theory. My guess would be that the variety of neutral intervals might be attractive for maqam music, if the idea is to have a comparatively small system where each note has its perfect fifth and fourth. With many thanks, Margo

Please state your present position clearly. I want to be sure I understand this. Are you asserting that you now believe Bach's drawing at the top of the WTC title page is meaningless as to tuning, and that Bach simply slammed Werckmeister's most famous layout onto his harpsichords more or less sloppily (i.e. with the tempered 5ths not done quite evenly, and B-F# noticeably less tempered than the other three)? Or are you saying something else? Brad Lehman

From: Margo Schulter (2007-12-05) Subject: interesting edit to wikipedia/microtonal music Dear Daniel (and All), Thank you for your very thoughtful remarks about "microtonality" as one dimension of musical technique or choice rather than a discrete genre. I very much agree, and might offer an illustration involving modal music. Please let me say that I do this with great modesty, given that my range of experience both in composition and theory may be quite circumscribed compared to yours in many areas. Given that your focus is mainly tonal, and mine modal, it's interesting to ask how this might influence intonational preferences. Quite possibly, we might draw sometimes on similar interval sizes used in somewhat different contexts, just as two natural languages might have some similar phonemes used in quite distinct grammatical systems. Given your mention of meantone, I thought I might again post an mp3 file and PDF score for a piece, _Intrada in F Lydian_, which I linked to in an article of some weeks ago. <http://www.bestII.com/~mschulter/IntradaFLydian.mp3> <http://www.bestII.com/~mschulter/IntradaFLydian.pdf> If I were asked to describe the genre of this piece, I might say "Manneristic," referring to the era of around 1540-1640 in European music. More specifically the piece uses a variation on Zarlino's 2/7-comma meantone; but a listener might hear and recognize the general period style without focusing on this intonational aspect, much less the fact that this is a _modified_ meantone where the major third and sixth in Eb-G-C, for example, will be a full syntonic comma wider than in Zarlino's regular temperament. While the intonational dimension is indeed meant to be significant, I suspect that many other aspects of counterpoint and harmony around 1600 play a central role in shaping the piece. It would be quite possible to use a meantone (regular or modified) for some tonal music around 1720, say; but here the style would produce different results, even were the interval sizes quite similar. A metaphor I am tempted to draw involves the early years of typesetting and page layout on personal computers, then widely celebrated as "desktop publishing." A common refrain of experienced typesetters in that era, and even of some not-so-experienced ones, was that the main emphasis needed to be placed on desktop _publishing_. In others, simply learning a given software program was not a satisfactory substitute for the often more daunting task of mastering the craft of typography and graphic design. Similarly, understanding or emulating the style of Nicola Vicentino involves more than understanding meantone tunings, enharmonic dieses or fifthtones in a temperament around 1/4-comma or 31-EDO, and the altered intervals which occur in a 31-note circle. The style is also shaped by the conventional patterns of 16th-century counterpoint and harmony to which Vicentino devotes much of his treatise of 1555. Please let me say that although I recognize the merits of your observation that sometimes sticking to theoretical discussions avoids the possible sensitivities and even injuries that might arise when a given piece by a given participant becomes a focus for discussion, yet I would love to hear some of your music, whether posted here or available elsewhere. I am sure that it offers much enjoyment and education alike. Most appreciatively, Margo Schulter [email protected]

From: Margo Schulter (2007-12-07) Subject: Re: interesting edit to wikipedia/microtonal music Dear Magnus, Thank you warmly for your enthusiastic response to _Intrada in F Lydian_, and also your Web site, which includes some evidently very extended pieces that I look forward to hearing. An essay by Siemen Terpstra which you have very helpfully made available on your site raises some issues about the potentials of modified meantone tunings, and how the resources of these tunings may resemble or different somewhat from those of 31-EDO or a very similar 31-note circle of 1/4-comma meantone. Currently I am exploring some of these questions in a composition using Zest-24, a tuning based on two 12-note circles of the modified meantone system used for the Intrada. Your generous encouragement, your own music and ideas, and the Terpstra essay you have made available all lend impetus to this effort. I am not sure if I will be able to complete this composition before leaving for a holiday visit with my mother, but whenever I have an opportunity to do so and share the piece with you, please take it as a tribute to your music and wise counsel. Most appreciatively, Margo Schulter [email protected]
From: Margo Schulter (2007-12-07) Subject: Re: Stockhausen Dear Daniel, Please let me add my tribute to Stockhausen and his music. I recall hearing it in an undergraduate course in contemporary music -- curiously, the one college course in music that I can recall taking. His music indeed sounded very distinctive, modern, and awesome. Of course, I regard intonation as only one dimension of musicality, and by no means always the most significant in shaping a composer's or listener's sense of identity and affinity. Thus I would regard the neomodality of Debussy or Vaughan Williams as a shaping influence of my own music, for example, as well as the modality and quartal/quintal styles of Bartok, quite regardless of whether this music happens to be performed in 12-EDO or some other system. Thus I express my great affection and appreciation to Stockhausen for having conceived of such unique and transforming edifices of sound -- rather as I am enthralled by aural architectonics of Perotin. Of course, as Stockhausen's own use of intonational variation shows, a plurality of tuning systems can multiply the possibilities. Most appreciatively, Margo Schulter [email protected]

From: Margo Schulter (2007-12-17) Subject: Letter before trip Hello, everyone. Since I'm leaving tomorrow for a visit with my Mom, please let me say that I'm in the middle of a composition for Annika (also known as the daughter of the one and only AKJ) that I hope to finish when I get back next month. Also, why don't I share some notes about a subset of Zest-24 that I'm exploring called Goya/Supergoya. The basic Goya-17 features a set of major, minor, and neutral intervals with reference to a "1/1" of Db that somewhat resemble, but often radically differ from, a 17-tone circle such as George Secor's 17-WT. Generally major septimal intervals from Db are approximated using the chain of fifths on the lower keyboard, while the upper keyboard supplies approximations of minor septimal intervals and also neutral intervals, as explained more in the notes. Supergoya-17plus3 adds some approximations of septimal ratios such as 21:16 and 189:128. This makes some basic 17-tone-style resolutions available at more locations, but also facilitates idioms which favor sonorities such as 16:21:24:28 or the narrow and wide fourths and fifths (and octaves!) of gamelan. Here's a link to this very rough sketch, more of an essay in progress than anything, but possibly curious to some here. <http://www.bestII.com/~mschulter/letter-goya-supergoya.txt> Also, here's a Scala file of a tuning set which I hope by some time early next year will have some mp3 files to illustrate its potentials -- from me, with others warmly encouraged to join in also if this system looks interesting. ! zest24-supergoya17plus3_Db.scl !
