Harmonic Highlights

  • Employs a “backdoor” ii-V sequence (Bbm7 - Eb7) resolving to Fmaj7, utilizing subdominant minor functionality.
  • Features chromatic parallel motion (Am7 - Abm7 - Gm7) providing smooth step-wise voice leading into the primary cadence.
  • Incorporates modal interchange with the Abmaj7 (bIII), momentarily drawing from the parallel F minor tonality.
  • Relies on a strong tonic-dominant foundation in F major, embellished by secondary subdominant movements.

Improvisation Focus F Major scale fluency with a shift to Bb Melodic Minor (Eb Lydian Dominant) to capture the color of the backdoor ii-V.

Difficulty Rating 3/5 β€” While largely diatonic, the player must skillfully navigate the chromatic passing chords and the non-functional subdominant minor shifts.
