The Exhaustive Piano & Guitar Chord & Scale App
For Students, Composers, Songwriters, Arrangers & Working Musicians
Start with what you know and follow your curiosity, exploring until you become familiar with the entire sonic terrain. Be confident that you have all musical options at your disposal, since Harmonious is the first complete chord and scale map.* Harmonious is a complete map of all chromatic-cluster-free hexatonic, heptatonic, and octotonic scales and modes and their compatible chords (Levine 1995) in twelve-tone equal temperament. Find extensions, substitutions and chromatic flavors that lie at the edge of the familiar and the exotic. See connections through the dual lens of chords and scales, linking harmony and melody.
