Note:
1/1 is implicit in the Scala file format;
input pitches are automatically normalised
and sorted, thus scales are octave-repeating.

AUTO-NORMALISED ENHARMONIC PITCH-CLASS COMPARISON

simplified to a Pythagorean notation modified, optionally, by up to
3 syntonic commas and/or one of the primes 7, 11 or 13, and
inflected by up to 3 strokes each signifying ca. 1/6-comma
