Part 4/6:
Key to this progression is the drop of the perfect fourth by half step repeatedly, a device that creates smooth voice-leading and a subtly destabilizing effect. It employs a Chelsea upward spirit, starting from a Lydian major chord (E-flat Lydian with a sharp four), adding even more jazz flavor, descending eventually to a D minor 6/9 that provides a lush, dramatic resolution.
Progression 3: From E-flat Major over A-flat to G (The Aolian Voicing)
This progression showcases a rich set of voicings:
Starts with an E-flat major over A-flat (bass),
Moves to an A-flat major over D-flat,
Then to an A G chord—an Aolian sounding voicing with G, F, B-flat, D, and E-flat,
Finally resolves to a C major chord with spread voicing (G and C in the bass).
