- The bridge features a demanding sequence of ii-V-I progressions descending by whole steps (Bmaj7, Amaj7, Gmaj7), requiring mastery of distal key centers.
- It utilizes a classic I - ii/V - IV move (Bb6 to Fm7-Bb7 to Ebmaj7) followed by a backdoor bVII7 (Ab7) resolution back to the tonic.
- The structure follows the “Cherokee” changes, characterized by secondary dominants and rapid-fire chromatic ii-V substitutions typical of high-speed Bebop.
Improvisation Focus Fluent navigation of sequential ii-V-I cells at extreme tempos.
Difficulty Rating 5/5 – The relentless tempo and rapid modulations through the bridge demand virtuosic technical facility and advanced harmonic mapping.
