Find Lead Sheet on Sheet Music Direct (PDF)Harmonic Highlights
- The A section employs a ii-V of IV (Fm7–Bb7 to Ebmaj7) followed by an Ab7 backdoor dominant, creating smooth chromatic voice leading back to the Bb tonic.
- The bridge is a masterclass in sequential modulation, descending in whole steps through II-V-I progressions in B major, A major, and G major.
- Frequent use of secondary dominants, such as the C7 (V/V), adds harmonic tension before returning to the final A section.
Improvisation Focus Navigating rapid II-V-I cycles in distantly related keys during the bridge.
Difficulty Rating 5: The bridge’s sophisticated modulations combined with the traditionally blistering tempo make this a definitive “rite of passage” for advanced jazz musicians.
