The PCS-ANALYSIS function returns two more results: inverted-form and interval-class: (pcs-analysis '(4 1 8 10 3 7)) => Sequence: (4 1 8 10 3 7) Set: 6-z29 Prime Form: (0 2 3 6 7 9) Inverted Form: nil Pitch: (c4 d4 eb4 fs4 g4 a4) Normal Order: (1 3 4 7 8 10) Complement: (0 2 5 6 9 11) Inversion: (8 11 4 2 9 5) Vector: (2 2 4 2 3 2) Interval Class: (3 5 2 5 4) (pcs-analysis '(0 3 7)) => Sequence: (0 3 7) Set: 3-11 Prime Form: (0 3 7) Inverted Form: (0 4 7) Pitch: (c4 eb4 g4) Normal Order: (0 3 7) Complement: (1 2 4 5 6 8 9 10 11) Inversion: (0 9 5) Vector: (0 0 1 1 1 0) Interval Class: (3 4) (pcs-analysis '(0 4 7)) => Sequence: (0 4 7) Set: 3-11b Prime Form: (0 3 7) Inverted Form: (0 4 7) Pitch: (c4 e4 g4) Normal Order: (0 4 7) Complement: (1 2 3 5 6 8 9 10 11) Inversion: (0 8 5) Vector: (0 0 1 1 1 0) Interval Class: (4 3) The new function PCS-FORMS takes care of both forms: prime-form and inverted-form. The inverted form set ends with letter b: (pcs-forms '((0 4 7) (0 3 7)) :type :set) => (3-11b 3-11)
