Harmonic Highlights:
- Frequent tonicization of the IV chord (Abmaj7) via Bbm7-Eb7 and the iii chord (Gm7) via Am7b5-D7, demonstrating fluid shifts in key center.
- Extensive use of ii-V-I progressions and secondary dominants, chaining through multiple temporary tonal areas before resolving back to the tonic.
- The appearance of the bVII7 chord (Db7) provides a distinctive backdoor dominant sound, leading to the IV chord (Abmaj7).
Improvisation Focus: Applying various dominant alterations (e.g., b9, #9, #11) to highlight the tension and resolution inherent in the numerous V7 chords.
Difficulty Rating: 4 (Advanced-Intermediate) due to the rapid harmonic rhythm, frequent tonicizations, and the variety of dominant chord qualities requiring precise navigation.
