Harmonic Highlights

  • Employs the quintessential I-vi-ii-V (F6–Dm7–Gm7–C7) “rhythm changes” turnaround as the primary structural loop.
  • The bridge utilizes a secondary dominant chain (A7–D7–G7–C7), cycling through the circle of fifths to resolve back to the tonic.
  • Frequent use of iii-vi-ii-V substitutions (Am7–Dm7–Gm7–C7) creates smoother stepwise voice leading compared to the standard tonic start.
  • Incorporation of the IV chord (Bbmaj7) provides a brief subdominant departure before re-entering the dominant cycle.

Improvisation Focus F Major Pentatonic/Hexatonic scales to emphasize the melodic simplicity of the I-vi-ii-V cycle.

Difficulty Rating 1/5. Its repetitive diatonic structure and predictable secondary dominants make it the foundational exercise for entry-level jazz harmony.
