The Note class

Notes can be specified with either a name or a given number of semitones above middle C (C3). Octaves are done MIDI-style, so B2 is immediately followed by C3. Example notes:

Note("D") the first D above middle C
Note(2) two semitones above middle C, which is the same as Note("D").

Notes have two fundamental properties:

.name e.g. "C"
.octave e.g. 3

You can retrieve both together MIDI style with:

.midi e.g. "F#4"

You can add an integer to a note to raise it by that many semitones:

Note("C") + 12 the first C above middle C

Examples

musical_scales.scale("D")
# Defaults to major scale
# [D3, E3, F#3, G3, A3, B3, C#4, D4]
musical_scales.scale("F#", "blues")
# [F#3, A3, B3, C4, C#4, E4, F#4]
