From: Kalle Aho (2008-04-08) Subject: A Rational Well Temperament Hi everyone, I thought about searching for a well temperament where the notes are harmonics of a common fundamental. The criteria were that there would be no harmonic waste (combined absolute 5-limit error is no greater than in 12-equal) and the series of harmonics should be as low as possible in the harmonic series. I think that the following series fulfills these criteria: 116:123:130:138:146:155:164:174:184:195:207:219:232 Similar rational versions can be found for other equal temperaments (and possibly for scales too). For example a corresponding rational temperament for 22-equal with no 7-limit harmonic waste would be 149:154:159:164:169:174:180:186:192:198:204: 211:217:224:232:239:247:255:263:271:280:289 Kalle Aho

What happens with 12-ET and 7-limit harmonic waste? Hi Carl and everybody, Interestingly, there's no difference to the 5-limit case. Same with 9-limit. 22-equal and zero 9-limit harmonic waste gives a tuning which you can get when you write the following in Scala: equal 22 quantize/linear 1/381 key 21 Notice that by rotating the result (the "key 21" command) gives even lower terms so I'm not 100% sure this is as low in the harmonic series as possible. I searched through all linear quantizations of 22-equal but I'm not sure if there could still be a lower one which differs from a linear quantization. A brute force search by a computer program that takes this into account would take absurdly long time. Kalle

I did a computer search for 12-tone one where the linear quantizations are offsetted by +1,0 and -1 so for every linear quantization the program checks 3^11=177147 different possibilities. So I'm quite sure about the 12-tone case. For 22-tone the program would have to go through 3^21 possibilities for every linear quantization which is just way too much. The nth linear quantization (in case you're wondering what that is) for x-equal you get with round(n*2^(y/x)) where y goes from 0 to x

Smart work. That's a keeper. Thanks, Carl! By the way, 19-tone 5-limit tuning seems to be the following: in Scala, type equal 19 quantize/linear 1/1374 key 18 This tuning is much higher in the harmonic series than 12-tone and 22-tone ones.

Searching this way gives the following approximate values for n (two decimal places): 12-tone 5,7 and 9-limits 115.89 19-tone 5-limit 1324.71 22-tone 7-limit 124.13 22-tone 9-limit 369.03 13-tone Bohlen-Pierce 7-limit 104.65 Kalle Aho

From: Tom Dent (2008-04-09) Subject: Re: A Rational Well Temperament Werckmeister's solution with monochord lengths (equivalent to subharmonics of some extremely high frequency) was 196 186 175 165 156 147 139 131 124 117 110 104 98 Many of these numbers are closely related to Kalle's, but not quite. The ratio 39/31 for a major 3rd is also familiar. If we invert it and take the lowest possible integer representation we have 93 98 104 110 117 124 131 139 147 156 165 175 186 ... the catch is that there is a tiny bit of 'harmonic waste' here. What Kalle is doing is also equivalent to my attempts to build temperaments with integer frequencies, if you allow a free choice of pitch. I guess A=390 would have been a good one! It is also equivalent to factoring the Pythagorean comma into superparticular ratios (a pastime of Sparschuh's) as 261/260 . 585/584 . 657/656 . 369/368 . 621/620 . 465/464 Now what is the smallest 12-integer series you can have (with or without 'harmonic waste') where no fifth is tempered more than 1/4 comma? I.e. the largest superparticular factor is 321/320 or smaller? I once found http://launch.groups.yahoo.com/group/tuning/message/58680 E 315 F 335 F# 354 G 376 G# 398 A 421 Bb 447 B 472 C 502 C# 531 D 563 Eb 597 but I'm sure one can do 'better' in terms of reducing the size of the numbers. ~~~T~~~ --- In [email protected], "Kalle Aho" <kalleaho@...> wrote: > > Hi everyone, > > I thought about searching for a well temperament where the notes are > harmonics of a common fundamental.

Hi Shaahin, notice that there exists even lower 22-tone harmonic mode with no 7-limit harmonic waste where the series begins with 124 but your excel sheet doesn't give this one because it doesn't take into account those in between quantizations I talked about in message 75833.

Perhaps you put a limit on the smallest narrow fifth but not on the largest wide one. Noting that 285=3*95, I think the smallest base number that allows all fifths to be tempered less than 321/320 will turn out to be over 107. ~~~T~~~

Regarding your original suggestion, I have both positive and negative comments. (I'll give the negative first.) At first I was a little hesitant to call this a well-temperament, because most of the pure 5ths alternate with tempered 5ths as you go around the circle of 5ths. In a good well-temperament (pardon the redundancy) most (if not all) of the pure 5ths should be consecutive in order to achieve monotonic interval sizes around the circle of 5ths. However, as Carl pointed out, there is a reasonable progression of size for the major 3rds. If 116 is C, then your best major triads are on Bb, C, and F (in order of increasing error), which tends to favor the flat keys, and the worst is either F# or C# (depending on whether you consider major-3rd error or total-triad error to be more important). If you make 155 C, then the best triads are F, G, and C (in that order) and the worst either C# or G#, which is not ideal. I think that a listening test will be required to determine which number would be preferable as C, and whether the differences among the best triads are all that significant. On the plus side: 1) I think you've outdone Robert Wendell in the synchronous well- temperament category, because you've succeeded in getting fairly simple brats in *all 24* major and minor triads. (RW completely disregarded the minor triads.) 2) The cents errors seem to indicate that no triad is going to sound significantly worse than 12-equal, which puts this tuning in the synchronous modern well-temperament category (SMWT, for short) -- I noticed that Carl saw this. The bottom line: this one definitely deserves a listen. --George

After writing that, I wondered how low the numbers could be for a WT with all of the pure fifths occurring consecutively (and no harmonic waste). I found this one, with five pure fifths: 364, 384, 408, 432, 456, 486, 512, 545, 576, 610, 648, 683, 728 Taking 364 as C, the best major triads are on C, G, and F, D, Bb, and A (in that order) and the two worst are F# and C# (both Pythagorean). The brats aren't quite as simple as in your synchronous modern well- temperament (SMWT), but they're not so much more complicated as you might expect, because only two of the harmonics in the above sequence are odd numbers, and seven of them are divisible by 4. I'm going to call this one my "24c", since it's the third one in my collection of well-temperaments that has reasonably simple brats in all 24 major and minor triads. Since Carl wants a Scala file, here it is: ! WTPB-24c.scl ! George Secor's 24-triad proportional-beating well-temperament (24c) 12 ! 96/91 102/91 108/91 114/91 243/182 182/91 545/364 144/91 305/182 162/91 683/364 2/1 I was curious to compare both your SMWT and 24c with the two well- temperaments (24a and 24b) that I found a couple of years ago: http://tech.groups.yahoo.com/group/tuning-math/message/13733 Also see these links for answers to questions about 24a and 24b and WT brats in general: http://tech.groups.yahoo.com/group/tuning-math/message/13737 http://groups.yahoo.com/group/tuning/messages/66380 Here's how they stack up, ranked in order of simplest brats: major triads only: 24a, 24b, SMWT, 24c minor triads only: SMWT, 24c, 24a, 24b all 24 M&m triads: SMWT, 24a, 24c, 24b I prefer 24b to 24a, because 24a, in spite of having monotonic 3rds, does not have all pure 5ths consecutive in the circle of 5ths. Also, 24a has IMO too much contrast (i.e., the C major triad has too low an error compared to the rest). --George

The four best major 3rds all occur consecutively on one side of the circle of 5ths, so there is a general key contrast such as one expects in a WT. But since the key contrast of this (modern) WT is rather low, I think that the synchronous beating becomes a more notable feature, relatively speaking. > > ... > > I think that a listening test will be required to determine which > > number would be preferable as C, and whether the differences among > > the best triads are all that significant.

AFAIK, the hardanger fiddle has eight (or nine?) strings, only four of which are meant to be played. The rest are short resonating strings tuned to some higher pitches which are fifths or thirds from some of the lower tones, I don't know exactly how it works. The point is that this makes the player learn to play as much in tune as possible. A few years ago, there was a programme on the Czech tv where recordings of some hardanger violinists were played, I mean, not only in groups but also solo players. I was surprised how close their intonation was to 5-limit JI even with the tiny commatic differences -- one of them, when playing in E major, played B-G# almost like 5/3 and B-A almost like 16/9 (I didn't actually hear the 16/9 but I could clearly hear the upper voice rising from G# to A by a nice minor second which I heard almost like 16/15). When he then changed to G major, he played B-A not as 16/9 but very close to 9/5 (which was quite logical because he was playing B-G before and it would break the harmonic series if he raised the upper voice by 10/9 instead of 9/8). What I know much more about is the overtone flute (meaning the one without finger holes) primarily because I like playing it myself. :-D It's surprising how many cultures také this instrument as their traditional folk instrument -- in Swedish "sälgflöjt", in Norwegian "seljeflöyte", in Slovak "koncovka" (sometimes we call it the same in Czech because some of the Moravian folk melodies are also played on this flute), also in Swahili it's "filimbi". Not knowing what it's called there, I've also read about it being used in the Solomon Islands. I have several here at home -- one of them is played like a recorder, the rest are transverse flutes. When I first played an overtone flute in 2003, I very quickly got the opinion that the harmonic series is the nicest series of intervals that has ever existed in music. If you like to know something more about the flute, let me know. > I have been disapoined with the ocora and the La Chant de Monde etc. recordings > i have gotten from finland. Why?

Well, I really don't know almost anything about the history of the events. Petr

Hi Petr, yes I am, originally from western Finland from the region of Ostrobothnia, now living in Helsinki. > PS: Do you have any idea where I could find some folk music from eastern Finland? I don't think this distinction is geographical as the instrument kantele which belongs to the eastern influenced tradition of folk music is also actively still played in western Finland too. While this older tradition is eastern influenced the distinction is more temporal than spatial so to speak. from http://www.fimic.fi/fimic/fimic.nsf/ "Finnish folk music can be roughly divided into two historical eras differing considerably from each other both in their music and culture and in their use in the community. The earlier stratum is often called the ancient Finnish period or the Kalevalaic era. It covers such genres as the singing of Kalevalaic poetry, the chain dance, the lament, and a distinctive brand of music performed on such instruments as the five-stringed kantele, the bowed harp (or crwth), and a host of folk wind instruments. The later stratum of Finnish folk music is the period of agrarian or pelimanni music and it is clearly rooted in Western culture." I suggest you look for records made with specific instruments like kantele or the bowed lyre. Those fimic-pages contain lists of records. My father, grandfather and other relatives were or are accordionists and associated with pelimanni music, that later scandinavia-influenced tradition of folk music. There is even some research done about my grandfather who was actually born in America for finnish parents: http://www.markkulepisto.com/sitahavois.htm Kalle

Again this difference is temporal, not spatial as the whole Finland used to be a part of the kingdom of Sweden until the year 1809 when Finland became an autonomous Grand Duchy in the Russian Empire until the end of 1917 when it became independent.

However, in spite of the somewhat lower numbers, the brats aren't as quite as simple as with my 24c (with five consecutive pure fifths): 364, 384, 408, 432, 456, 486, 512, 545, 576, 610, 648, 683, 728 for which I still haven't gotten the Scala listing right.

In fact, the two WT's are so much alike that all I needed for a rational version of your Young- Neidhardt hybrid was change two notes (B & F#): ! Dent-YN-RWT.scl !

This is probably the one I would prefer, because no fifth is tempered excessively. I see that the worst major triads are on B and E. This is similar to Brad's "Bach squiggle" temperament, but since you have no wide fifths, there's a smoother size progression for the major 3rds. Since you asked what I might "improve", here goes. If you substitute C# 530, Eb 596, F# 707/2, and G# 795/2, then D, A, E, and B will improve at the expense of F#, C#, Ab, and Eb, and the worst major triads will be on F# and C#. (Although there are now only 2 pure fifths (instead of 3), the brats are actually somewhat improved in the process.) As to whether favoring the sharp keys over the flats by this much is an "improvement" is, of course, a matter of opinion. I would have preferred to make it less sharp-biased, but it didn't work out that way with 502 as a common denominator. > !squiggle418cps.scl > 12 > Sparschuh's 2008 Cammerton a4=418Hz 'squiggle' > 176/167 !

This is a very high-contrast well-temperament, such that: 5 major triads (E thru G#) have thirds with >20c error, and the C major triad is so much better that all of the rest that I expect that it will stick out like the proverbial sore thumb. Also, the fifth A-E is very narrow (almost 9 cents). If you substitute D 560/501 and E 627/501, then: 1) The A-E error is cut to 6.2c; 2) The brats are much improved; 3) The contrast is lowered (by making C-E wider, so it beats at the same rate as C-G); and 4) There are now only 4 major triads (B thru G#) having thirds with >20c error. > > George's proposal: > > 364, 384, 408, 432, 456, 486, 512, 545, 576, 610, 648, 683, 728: > > > > !

BTW, I finally had a chance to listen to Kalle's synchronous WT and to compare it with some other rational temperaments, and I have two general observations: 1) Synchrony doesn't seem to be of much benefit when the thirds are beating quickly; 2) The general effect is much better if the tempering of *all* of the fifths is kept under some maximum, e.g., ~5 cents, or better yet, ~4.6 cents. (Achieving this in combination with simple brats is not easy.) --George

That's the maximum amount the fifths are tempered in my 5/23-comma temperament extraordinaire to give C & G major triads with equal beat rates for the 5th & M3, which are arguably as good as 1/4-comma meantone triads (if not better). See: http://groups.yahoo.com/group/tuning/message/74188 Since it has three wide 5ths, it's not a well-temperament. Nevertheless, it's my alternative to modified meantone temperaments (and also my favorite circulating 12-tone temperament). > Anyway, the following tuning has the errors of all fifths under 4.6 cents: > > ! > > 12 > ! > 224/211 > 237/211 > 252/211 > 266/211 > 282/211 > 299/211 > 316/211 > 336/211 > 355/211 > 377/211 > 399/211 > 2/1 Your best major triads are on Eb and Ab, and the worst are on B and E, so this would benefit from a transposition.

A=440 is my preference. (I see no reason why the frequencies of all of the pitches should be exact integers.) With most well- temperaments C will be higher in pitch than in 12-equal with A=440; for the rationalized Dent-Young-Neidhardt C will be ~262.5 Hz. --George

I believe there are still a few mistakes. From the sizes of the fifths you give, I think that perhaps you meant this: 558/529 ! C# 592/529 ! D 2511/2116 ! Eb = 627.75/529 1323/1058 ! E = 661.5/529 706/529 ! F 744/529 ! F# 792/529 ! G 837/529 ! G# 875/523 ! A = 442.5Hz*2 absolute a4 1883/1058 ! Bb = 941.5/529 992/529 ! B This will result in: F~ -1.636 ~C~ -3.276 ~G~ -5.839 ~D~ -5.784 ~A~ -5.953 ~E~ -0.436 ~B B F# C# G# Eb~ -0.2298 ~Bb~ -0.306 ~F --George
