This module contains miscellaneous functions for working with pitches and pitch-classes.
map_to_chromatic(scale_map, sequence)[int]
Takes a succession of diatonic pitch-classes and maps them to chromatic pitch-classes. For example, you can map diatonic scale degrees to chromatic scale degrees by providing the scale map {0: 0, 1: 2, 2: 4, 3: 5, 4: 7, 5: 9, 6: 11}, and transform a diatonic pcseg to a chromatic pcseg using this function.
norgard(n: int)[int]
Generates the first n numbers of Per Norgard's “infinity series,” OEIS A004718.
