[CM] Tuning Systems in cm3

[Heinrich Taube]

the (scale ....) function will define either 'modes' or  
'tunings'  (which, in cm3, are just lists of floating-point key  
numbers.) here are a few examples.

; three octaves (22 steps) of d dorian scale

(define d-dorian (scale 22 62 2 1 2 2 2 1 2))

;; three octaves (15 steps) of a 5-tone equal tempered scale

(define 5-tone-equal (scale 15 60 2.4))

;; three octave of a justly-tuned major scale

(define just-major-scale
   (scale 22 60 (ratio->steps '(9/8 10/9 16/15 9/8 10/9 9/8 16/15))))
