Harmony

This submodule contains objects that are related to harmony elements.

The basic harmonic elements are:

• Key: A tonic and mode (additionally it can have a chord progresison as attribute)

• Chord Progression: A list of chords

• Chord: List of 2 intervals (triad chords), 3 intervals (7ths), etc.

• Interval: List of 2 notes.
