The Future of Harmonic Exploration
The Map of Modal Harmony considers that
all harmony exists upon
the newly-charted fabric that is the
Matrix of 119 Modes.
The Map is so accurate that a Mode can be given for any random chord.
Play a game of Harmony Dice on your home computer:
The Modes are moody perspectives, with each starting its viewpoint at its Bass Note. A song tells a story of these perspectives changing, and Modulation causes sensation of an additional dimension. Be sure you can hear the Bass while watching these videos.

A Spectrum of Modes can be seen in the Key of C, with each Colored Note as a Bass forming a Mood.
The Modes have a spectral relation through the Circle of 5ths, as an invisible dimension accompanying the Chromatic Realm we see.

For our Perception of Harmony to be charted with a Map of Harmony, two more dimensions were needed. These reveal unseen facets of the Chromatic Realm.
