- Employs major-third root relationships, cycling through Ab, E, and C major centers, predating the “Coltrane changes” concept.
- The opening Emaj7 acts as a chromatic bVI in the home key of Ab, creating a distinctive non-functional harmonic entry.
- Utilizes sophisticated slash-chord inversions (G#7/D#, F7/C) to maintain smooth, stepwise bass motion despite frequent modulations.
- Integrates ii-V sequences that resolve unexpectedly, such as the Cm7b5–F7b9 turnaround used to pivot back into the complex main theme.
Improvisation Focus Vertical navigation of shifting tonal centers via smooth guide-tone voice leading.
Difficulty Rating 4/5. The frequent modulations to distantly related keys and non-standard resolutions require advanced harmonic fluency and a highly developed ear.
