I like it, but the comma is called the semicomma on Manuel's list.

I called it "Neutral Thirds". "Minor chromic" is another possibility.

Minor diesic? I think Paul named this; his names sounded good and maybe I should dig them out and keep them handy!

Magic--or Small Diesic for anyone who really digs this nomenclature.

78732/78125 = 2^2 3^9 5^-7

You'd think this would be some sort of diesis, but I can't find it.

"The Quite Small Diesis" won't do, I suppose.

This is Wuerschmidt's comma, so obviously the temperament is the Wuerschmidt. Who the heck is Wuerschmidt?

Paul said it was associated with Pelog. Pelogic?

Paul suggested "Octo-diminished", since it can be done very well by the 64-et. Sounds fine to me.

> > 128/125

"It's the augmented system, since the 6-tone MOS is commonly known as

the augmented scale" according to Paul.

I'm going to die sick. I'm going to Diesic.

Do you read German? If so, you should seek out his research. He found

some very interesting stuff, essentially looking into periodicity

blocks before Fokker.

This piqued my interest, so I took a look at the

Tuning and Temperament Bibliography

http://www.xs4all.nl/~huygensf/doc/bib.html#W

and take the liberty of quoting the Joseph Wï¿½rschmidt listings:

"Logarithmische und graphische Darstellung der musikalischen Intervalle",

Zeitschrift fï¿½r Physik vol. 3, 1920, p. 89.

"Viertel- und Sechsteltonmusik, eine kritische Studie",

Neue Musikzeitung vol. 42, 1921, p. 183.

"ï¿½ber die neunzehnstufige Temperatur",

Neue Musikzeitung vol. 42, 1921, p. 215.

"Buchstabentonschrift und Von Oettingensches Tongewebe",

Zeitschrift fï¿½r Physik vol. 5, 1922, p. 111.

"Die rationellen Tonsysteme in Quinten-Terzengewebe",

Zeitschrift fï¿½r Physik vol. 46, January 1928, p. 527.

"Tonleitern, Tonarten und Tonsysteme. Eine historisch-theoretische

Untersuchung",

Sitzungsberichte der Physikalisch-medizinischen Sozietï¿½t zu Erlangen,

Band 63, 1931, pp. 133-238.

"Die neunzehn-stufige Skala; eine natï¿½rliche Erweiterung unseres Tonsystems"

(The 19-tone scale; a natural expansion of our tonal system),

Neue Musikzeitung vol. 14 no. 4, 1921, pp. 215-216.

Which of these have you read, Paul? Can you summarize?

I wonder if Tanaka wrote about periodicity-blocks before Wï¿½rschmidt?

None, but Mandelbaum touched on his work. A lot of it involves a

conception of "rational tone-systems", which are essentially 5-limit

periodicity blocks, expressed with only three step sizes, but then

equally tempered anyway. W.'s "rational tone systems" included 12-,

19-, 22-, 31-, 34-, 41-, 53-, 65-, and 118-tET, and there weren't

many more given the constrains he imposed.

that should be 2^9 3^-13 5^5, right?
