addon/mixins/musical-identity.js:17

MusicalIdentity

This mixin allows an object to have an awareness of it's "musical identity" or "note value" based on western musical standards (a standard piano). If any of the following are provided, all of the remaining properties will be calculated:

  1. frequency
  2. identifier (i.e. "Ab1")
  3. letter, octave, and (optionally) accidental

This mixin only makes sense when the consuming object is part of a collection, as the only functionality it provides serves to facilitate identification.
