This diagram explores modal relationships, graphing the type of diatonic 7th chords built on each scale degree of a given mode. 7th chords are arranged based on their intervallic content - M7 chords having the most major thirds, and half diminished containing the most minor thirds. The lower digram overlays these graphs, illustrating the cyclical nature of diatonic modes.
