Harmonic Highlights

  • Employs a chromatic descending turnaround (Am7โ€“Abยฐ7โ€“Gm7) where the diminished chord acts as a passing chord to the ii7.
  • Utilizes a secondary dominant ii-V (Cm7โ€“F7) to tonicize the IV chord (Bb6), a hallmark of swing-era song forms.
  • Features a II7 (G7) secondary dominant, creating a strong circle-of-fifths resolution toward the dominant Gm7โ€“C7.
  • The structure follows a standard AABA 32-bar form, relying heavily on functional ii-V-I resolutions in F major.

Improvisation Focus F Major Bebop Scale (incorporating the chromatic passing tone between C and D).

Difficulty Rating 2/5: The harmonic rhythm is predictable and the modulations are limited to closely related keys, making it accessible for developing soloists.
