Fwd: Re: Musical practice and discourse about music

This is what I meant:

] = 1/4 tone up
> = 1/6 tone up
^ = 1/12 tone up
v = 1/12 tone down
< = 1/6 tone down
[ = 1/4 tone down

The "two decatonic scales a twelfth-tone apart in 72-tET", for the
dynamic symmetrical case, would be (with the number of tetrads each
pitch is involved in in parentheses):

C (3) C^ (1)
C# (2) C#^ (1)
Eb< (1) Ebv (2)
E< (1) Ev (3)
Fv (1) F (1)
F# (3) F#^ (1)
G (2) G^ (1)
A< (1) Av (2)
Bb< (1) Bbv (3)
Bv (1) B (1)
