- The tune employs a ii-V-I progression (Bbm7-Eb7-Abmaj7) that tonicizes the IV chord before returning to the tonic.
- A distinctive Abmaj7 - Db7 - Ebmaj7 (IV - bVII7 - I) progression uses a non-diatonic Db7 chord as a backdoor dominant, adding rich harmonic color.
- Frequent ii-V progressions target various diatonic functions, including the tonic (Fm7-Bb7) and the iii minor (Am7b5-D7b9 to Gm7), creating constant harmonic motion.
Improvisation Focus: Navigating ii-V progressions using chord-scale theory.
Difficulty Rating: 4 (Advanced Intermediate). The frequent, sometimes non-diatonic, chord changes and rapid harmonic rhythm demand attentive navigation.
