pub fn fix_default_octave_for_pitch_list(pitches: &[Pitch]) -> Vec<Pitch>Expand description
A collection’s notes with the octaves a caller left out filled in so that
the collection rises: music21’s fixDefaultOctaveForPitchList.
A B C D E F G# A is a scale on A, not a collection that climbs a tone
and then falls a seventh, and a caller who names no octaves means the
first. Notes that carry an octave are left exactly as they are.
