Harmonic Highlights:
- The tune heavily features the I7 (F7) moving to the IV7 (Bb7), establishing a blues-inflected dominant sound within the F major key center.
- A strong functional iii-VI-ii-V (Am7-D7-Gm7-C7) progression frequently resolves to the tonic F, providing traditional jazz harmonic movement.
- The progression incorporates a ii-V (Cm7-F7) that often leads to the subdominant Bb7, adding a temporary tonicization within the blues framework.
- The overall harmony effectively blends simple dominant 7th blues patterns with more intricate functional jazz voice leading.
Improvisation Focus: F Mixolydian scale.
