Harmonic Highlights
- The A-section utilizes a standard I-vi-ii-V7 turnaround (Db6–Bbm7–Ebm7–Ab7#5), establishing a stable tonic with melodic tension through the augmented dominant.
- The bridge employs an extended “Cycle of Dominants” (C9–F9–Bb9–Eb9), using secondary dominants to create harmonic momentum across the circle of fifths.
- A iii-VI-ii-V transition (Fm7–Bb7–Ebm7–Ab7) serves as a functional turnaround, bridging the gap between diatonic stability and the chromatic cycling of the B-section.
Improvisation Focus Voice-leading via 3rds and 7ths (guide tones) to navigate the rapid secondary dominant changes in the bridge.
Difficulty Rating 3/5: The repetitive A-sections are accessible for intermediates, but the bridge demands quick mental transposition through four distinct dominant-seventh centers.
