Module: MTK::Lang::Intervals

Extended by:
PseudoConstants
Defined in:
lib/mtk/lang/intervals.rb

Overview

Defines a constant for Core::Intervals up to an octave using diatonic naming conventions

Naming conventions

P#: perfect interval
M#: major interval
m#: minor interval
TT: tritone
a#: augmented interval
d#: diminished interval

These can be thought of like constants, but in order to support the lower case names, it was necessary to define them as “pseudo constant” methods. Like constants, these methods are available either through the module (MTK::Lang::Intervals::m2) or via mixin (include MTK::Lang::Intervals; m2). They are listed under the “Instance Attribute Summary” of this page.
