monzo_sumerian_12edo_2place

From: monz (2003-07-06)
Subject: updated Sumerian 12edo page

i'm guessing that back when i posted my webpages
speculating how the Sumerians might have been
able to approximate 12edo over 5000 years ago,
most people's eyes probably glazed over
uncomprehendingly, thanks to all the base-60 math.

well, i've just gone back in and added a bunch of
nifty graphs that show vividly what i'm explaining,
and i've also included the modern-style fractions
for the actual values which measure the string-lengths.

before, i only had the "theoretically correct" fractions,
but this is not exactly what you get when you round
the results of the calculations to 2 sexagesimal places.
now the diagrams include that.

also, since i have the fractions now, i've made
a Scala file for each version of the tuning:
