Accidentals abbreviations.

Names of canonical notes ('c', 'c#', 'd',...).

NoteAccidental associated to diatonic intervals.

Names of diatonic intervals ('unison', 'm2', 'M2',...).

Semitones shift associated to intervals .

Note values.

Number of an canonical notes (12).

Indexes of the root notes.

Names of root notes ('c', 'd',...)

Values of the root notes.

Semitones shifts associated with scales.

Scales associated with m (minor) and M (major).

Create a scale map that represents the pitch state for a keySignature. For example, passing a G to keySignature would return a scale map with every note naturalized except for F which has an F# state.

Interval name associated to a value.

Canonical note name associated to a value.

Return the interval of a note, given a diatonic scale. e.g., given the scale C, and the note E, returns M3.

Interval value associated to an interval name.

Return root, accidental and type associated to a key.

Return root and accidental associated to a note.

Note value associated to a note name.

Given a root and note value, produce the relative note name.

Given a note, interval, and interval direction, produce the relative note.

Return scale tones, given intervals. Each successive interval is relative to the previous one, e.g., Major Scale:

TTSTTTS = [2,2,1,2,2,2,1]

When used with key = 0, returns C scale (which is isomorphic to interval list).
