- The A-section utilizes the foundational I-vi-ii-V turnaround (Bb6-Gm7-Cm7-F7), establishing a cyclical diatonic movement common in the “Rhythm Changes” idiom.
- The bridge (B-section) shifts to a sequential “Cycle of Fourths” using dominant seventh chords (D7-G7-C7-F7), creating a series of secondary dominant resolutions.
- Chromatic voice leading is highlighted in the final A-section via the IV to #IV diminished movement (Eb7 to E°7), providing a smooth transition to the Bb/F (tonic 6/4) cadence.
Improvisation Focus The Bb Major Pentatonic/Blues scale for the A-sections, combined with chord-tone targeting (3rds and 7ths) to navigate the rapid dominant cycles in the bridge.
Difficulty Rating 3/5; the repetitive harmonic structure is approachable, but the typical “up-tempo” performance speed and the bridge’s modulating dominants require significant technical proficiency.
