- The A-section utilizes chromatic descending dominants (Db7 to C9 and Gb9 to F9) which function as tritone substitutions (subV) for the secondary dominants of the VI and II chords.
- The progression I–bVII7–VI7–subV/II–II7–V7 creates a dense, blues-inflected harmonic rhythm that prioritizes smooth downward voice leading over standard diatonic movement.
- Tonal stability is reinforced via a standard iii–VI–ii–V turnaround (Gm7–C7–Fm7–Bb7), providing a functional diatonic contrast to the highly chromatic nature of the primary theme.
Improvisation Focus The Eb Major Blues scale, utilized to bridge the gap between tonic stability and the shifting 3rds and 7ths of the chromatic dominant chain.
Difficulty Rating 2/5. The slow tempo and logical voice leading allow intermediate players to navigate the chromatic substitutions without the pressure of high-speed execution.
