Harmonic Highlights

  • Employs frequent I-vi-ii-V turnarounds (F6-Dm7-Gm7-C7) to establish a cyclical, driving rhythmic feel characteristic of the swing era.
  • Utilizes secondary dominants like the iii-VI7 (Am7-D7) to create chromatic internal motion that resolves predictably to the ii-V (Gm7-C7).
  • Features an ascending chromatic bass line (F7/A to Bb6 to Bยฐ7) that provides a gospel-inflected linear transition toward the tonic.
  • The bridge sequences ii-V progressions to modulate briefly toward the subdominant (Bb major), requiring quick tonal adjustments.

Improvisation Focus F Major Bebop scale (F, G, A, Bb, C, Db, D, E) to maintain melodic flow over rapid diatonic changes.

Difficulty Rating 3 (Intermediate); the harmonic language is straightforwardly diatonic, but the traditionally “bright” tempo demands high-velocity precision and clean voice leading.
