Module: MTK::Lang::Pitches

Defined in:
lib/mtk/lang/pitches.rb

Overview

Note:

Because the character ‘#’ cannot be used in the name of a constant, the “black key” pitches are all named as flats with ‘b’ (for example, Gb3 or Cb4)

Note:

Because the character ‘-’ (minus) cannot be used in the name of a constant, the low pitches use ‘_’ (underscore) in place of ‘-’ (minus) (for example C_1).

Defines a constants for each Core::Pitch in the standard MIDI range using scientific pitch notation.

See en.wikipedia.org/wiki/Scientific_pitch_notation
