Harmonic Highlights

  • Frequent use of the ii-V7-I cadence (Cm7-F7-Bb6) provides a stable diatonic foundation typical of the Swing era.
  • The secondary dominant G7 (V7/ii) acts as a pivot, creating tension that resolves predictably to the ii chord (Cm7).
  • Functional iii-VI-ii-V movement (Dm7-G7-Cm7-F7) facilitates a smooth cycle-of-fifths transition during the bridge sections.
  • Tonic stability is maintained through the use of Bb6, avoiding the tension of a major 7th and reinforcing the tune’s traditional “hot jazz” flavor.

Improvisation Focus Voice-leading through guide tones (3rds and 7ths) to highlight the transition from G7 (B natural) to Cm7 (Bb).

Difficulty Rating 2/5: The clear harmonic rhythm and standard functional progressions make it an ideal vehicle for practicing basic ii-V-I vocabulary.
