- The progression employs a chromatic ascending #I°7 (E°7) as a passing chord between the Imaj7 and iim7, facilitating smooth bass motion.
- It features a “backdoor” cadence (IVmaj7 to bVII7), where Abmaj7 moves to Db7#11 before resolving back to the tonic Ebmaj7.
- The bridge contains a sudden modulation to the distant key of B major (approached via F#m7 - B7), requiring a shift to the bVI tonal center.
- Constant use of extended ii-V-I cycles reinforces the Eb major tonality while using secondary dominants to create harmonic tension.
Improvisation Focus Navigating the “backdoor” bVII7 chord (Db7#11) using the Ab melodic minor scale to highlight the Lydian Dominant sound.
Difficulty Rating 3/5; the A sections are standard jazz vocabulary, but the sudden, distant modulation in the bridge requires intermediate harmonic navigation.
