Module: MTK::Lang::PitchClasses

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

Overview

Defines a constant for each Core::PitchClass in the Western chromatic scale.

Because ‘#’ is not a valid identifier character in Ruby. All chromatic pitch classes are defined as the flat of a diatonic pitch class, for example Eb is a constant because D# is not a valid Ruby constant name.

To help automate the documentation, the constants are listed under “Instance Attribute Summary” on this page.
