Chord Reference

This document is a reference to the chords and scales use in MMA . It has been generated directly from the module chordtable.py in the MMA sources. Each section shows the chord name, a brief description, the chord notes for a ``C'' chord, and the associated scale tones. These chords and scales are used in MMA to generate chords, bass, arpeggios, arias, harmonies and scales.

In all cases you will need to preface the name with a chord pitch. For example, the reference for an 11th chord is listed simply as ``11''; you would use a ``C11'' or ``Eb11'', etc. in your MMA source file. Read the MMA Reference Guide if you don't understand this.

This document was prepared as a reference to verify the correctness of the chords and scales used in MMA . If you find an error, please let the author know.

MMA defines 95 unique chords plus 62 aliases. Chords used in MMA via aliased names are listed after the main name.
