Harmonic Highlights:

  • Chromatic ascending motion via F#o7 to bridge the ii chord (Fm7) and the tonic in first inversion (Eb7/G).
  • Frequent secondary dominant cycles, specifically the C7 (VI7) acting as V/ii to drive motion toward the Fm7-Bb7 turnaround.
  • Sustained use of subdominant harmony (Abmaj7) and its related ii-V (Bbm7-Eb7) to pivot during the bridge section.

Improvisation Focus: Eb Major Be-bop scale and chord-tone arpeggiation.

Difficulty Rating: 3/5. The functional harmony is accessible, but the high-velocity chord changes and common up-tempo performance practice demand rhythmic precision.
