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 CNote(2)
two semitones above middle C, which is the same asNote("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]
