Harmonic Highlights

  • Employs a classic iii-VI7-ii-V cycle (Gm7-C7-Fm7-Bb7), utilizing the VI7 (C7) as a secondary dominant to create harmonic tension and motion toward the supertonic.
  • Incorporates a secondary ii-V sequence (Bbm7-Eb7) to briefly tonicize the subdominant (Abmaj7), a common device in Great American Songbook standards to vary tonal color.
  • Features a dominant chain or circle-of-fifths progression (D7-G7-C7) that provides a strong directional pull back toward the primary ii-V-I turnaround in Eb major.

Improvisation Focus Voice leading through sequential ii-V-I cells.

Difficulty Rating 2/5. The predictable harmonic rhythm and reliance on standard functional jazz vocabulary make it highly accessible for students learning to navigate secondary dominants.
