Harmonic Highlights
- Initial descending whole-step major 7th progression (Cmaj7, Bbmaj7, Abmaj7, Gbmaj7) establishes a planar, non-functional harmonic motion.
- Frequent chromatic V-I resolutions, often incorporating tritone substitutions (e.g., B13 resolving to Emaj7), create rapid, non-diatonic tonal shifts.
- Prolonged sequences of parallel major 7th chords (e.g., Dbmaj7 through Dmaj7), moving by cycle of fourths or whole steps, generate pervasive modulation.
- The piece concludes with a stable Ab7sus vamp on the tonic, implying a modal color and open-ended resolution.
