Harmonic Highlights

  • Step-wise diatonic motion (Imaj7โ€“iim7โ€“iiim7) in the A section creates a smooth, linear melodic foundation.
  • Utilization of secondary dominants, specifically D7 (V7/ii) and G7 (V7/V), provides strong functional momentum toward the ii-V-I cadences.
  • The bridge emphasizes the subdominant (Bb6) and incorporates a G7 (V7/V) to build tension before returning to the tonic via a Gm7โ€“C7 turnaround.
  • Consistent ii-V-I resolutions reinforce a clear F major tonality, adhering to traditional swing-era harmonic structures.

Improvisation Focus F Major Bebop Scale.

Difficulty Rating 2/5. The harmonic progression is highly functional and predictable, making it an excellent vehicle for mastering foundational jazz vocabulary and guide-tone lines.
