Harmonic Highlights

  • Utilizes the structure of “What Is This Thing Called Love?”, alternating between minor ii-V-i cadences to the IV chord (Fm) and major ii-V-I cadences to the tonic (Cmaj).
  • Features a prominent modulation to the sub-tonic (Bb Major) in the bridge, utilizing a ii-V-I sequence (Cm7-F7-Bbmaj7).
  • Employs a bVI7 (Ab7) to V7 (G7) turnaround, functioning as a tritone substitution for the secondary dominant to create a chromatic resolution to the tonic.

Improvisation Focus Navigating rapid key center shifts through continuous eighth-note lines and smooth voice leading over alternating major and minor ii-V-I cells.

Difficulty Rating 4/5: The high-speed harmonic rhythm and frequent modulations require advanced facility with bebop vocabulary and precise targeting of chord tones across shifting centers.
