- Employs a recurring I - #I°7 - ii - V turnaround (Gmaj7 - Ab°7 - Am7 - D7), utilizing chromatic passing diminished chords for smooth bass voice-leading.
- Incorporates modal interchange via the IV to iv movement (Cmaj7 to Cm6), providing the signature “bittersweet” subdominant minor sound common in Gershwin’s era.
- The bridge shifts the tonal center to the VI (E major) and III (B major), requiring the soloist to navigate rapid secondary ii-V progressions in distal keys.
Improvisation Focus G Major Bebop Scale.
Difficulty Rating 3/5. While the A-sections are foundational jazz cycles, the bridge’s sudden modulations to E and B major demand intermediate-level harmonic fluencies.
