Harmonic Highlights:

  • The opening F6 (V6) and Eb6 (IV6) vamp establishes a modal, dominant-leaning feel over the implied Bb minor.
  • Immediate resolution from F7 (V7) to Bbmaj7 (Imaj7) signifies a swift shift from the implied minor to parallel major tonic.
  • A prominent II-V-I progression (Bbm7-Eb7-Abm7-Db7) unexpectedly resolves to Gbmaj7, demonstrating advanced key center modulation.
  • The C7 chord functions as a V7/V, creating a strong dominant motion back to F6 and perpetuating the harmonic cycle.

Improvisation Focus: Navigating major/minor tonic shifts and varied II-V-I resolutions.

Difficulty Rating: 3 (Intermediate). The frequent key center modulations and non-diatonic progressions demand a solid understanding of jazz harmony.
