- Employs a sophisticated variation of “Rhythm Changes” in Ab Major, replacing standard diatonic cycles with extended dominant structures like Bb7 leading to a ii-V (Bbm7-Eb7).
- The bridge features rapid-fire ii-V-I sequences descending through transient key centers (B, D, and C Major), requiring precise horizontal navigation across distant tonalities.
- Utilizes chromatic passing diminished chords (C#o7) and secondary dominants (F7 to Bbm7) to maintain forward motion within a high-velocity harmonic rhythm.
Improvisation Focus Navigating rapid ii-V-I cells using guide-tone connecting lines and Bebop scales.
Difficulty Rating 4/5. The combination of an extremely fast “burn” tempo and the dense, shifting tonalities in the bridge demands advanced technical facility and mental agility.
