[PD] more Fibonacci

[Charles Henry]

Yeah, I like the discussion of 19-tet systems.  I play a 19-tet
guitar, which I like very much.... you can find a figure in this
cartwright article:
http://www.imedea.uib.es/physdept/publications/downfile.php?fid=2576

on page 9, which shows mean quadratic dispersion (from just
intonation) of equal tempered scales as a function of the number of
subdivisions.  You can easily look at the function values for 5, 7,
12, 19, 31, 50 to see a decreasing series.  I think that this
decreasing series also holds for other fibbonacci sequences.  By the
way, I'm a big fan of cartwright.  Just google for his articles on
"dynamic system pitch cartwright," and I think you'll be pleasantly
surprised.
