Re: Improvisation in David Canright's 13 limit twelve tone

Hi Kraig,

Interesting to see that you and David are working on similar lines!

David: eight tone harmonic series:

1/3 1/1 5/3 7/3 3/2 11/3 13/3 5/1
1 3 5 7 9 11 13 15
Seven tone one on the 1/1:

1/1 3/1 5/1 7/1 9/1 11/1 13/1
1 3 5 7 9 11 13

Kraig:
1/3 1/1 5/3 7/3 3/2 5/1
1 3 5 7 9 15

1/1 3/1 5/1 7/1 9/1 15/1
1 3 5 7 9 15

(+ 21/5 7/5 7/9)

I'm enjoying improvising in your scale!
