- The progression features a distinctive tritone substitute (Gb7#11) resolving to the ii (Fm7), creating a chromatic bass line descending from the vi (Cm7).
- Modal interchange is utilized through the minor iv (Abm7) and ii-V patterns (Fm7b5 - Bb7b9), adding sophisticated subdominant coloration to the Eb major tonality.
- The bridge employs a modulation to the mediant (Gm) via a minor ii-V-i sequence (Am7b5 - D7b9 - Gm7), shifting the tonal center away from the home key.
- Frequent secondary dominants (C7b9, F7) and turnaround cycles (III-VI-II-V) create constant forward motion and harmonic density.
Improvisation Focus Navigating ii-V-I sequences with emphasis on guide-tone voice-leading and the G harmonic minor scale for the bridge modulation.
Difficulty Rating 3/5. It requires a solid grasp of chromatic voice-leading and the ability to pivot smoothly between Eb major and the temporary G minor center in the bridge.
