- Utilizes a standard “Rhythm Changes” structure in Bb major, characterized by a high-velocity I-vi-ii-V harmonic rhythm.
- The A-section turnaround incorporates a chromatic ascent from the IV chord (Eb6) via a diminished passing chord (E°7) to the tonic (Bb6/F).
- The bridge employs an extended cycle of fifths (D7–G7–C7–F7), using dominant seventh shells to create forward motion toward the final A section.
Improvisation Focus Rhythm Changes vocabulary, specifically targeting 3rds and 7ths to navigate the rapid dominant cycle in the bridge.
Difficulty Rating 4/5. The typically extreme tempo and relentless two-beats-per-chord harmonic rhythm require advanced technical facility and precise voice-leading mastery.
