note-class note [Function]

Returns the prime form of notes and its transposition offset. The prime form is the best normal form or its inversion, whichever is smaller. (The best normal form is the rotation the set ordered monotonically increasing with the fewest intervals spanned.) notes may be specified as note, degree or pitch references in the standard chromatic scale.

Example:

? (prime-form '(c4 ef4 f4))
(0 2 5)
0
