Basic row definition 

(setf row '(c4 e4 g4 bb4 d5 fs5 a5 gs5 f5 eb4 cs4 b4))

 

Extract some subsets from the row.

(setf set1 (subseq row 0 6))
(setf set2 (subseq row 3 9))
(setf set3 (subseq row 6 12))

 

Chords generation from sets

(setf couleur1 (gen-chord 12 5 5 -6 6 (gen-repeat 12 set1)))
(setf couleur2 (gen-chord 12 5 5 -6 6 (gen-repeat 12 set2)))
(setf couleur3 (gen-chord 12 5 5 -6 6 (gen-repeat 12 set3)))

 

Preparing tonality-series for futur mapping (create harmonics paths)

(setf path1 (tonality-series couleur1))
(setf path2 (tonality-series couleur2))
(setf path3 (tonality-series couleur3))
