Harmonic Highlights:

  • Utilizes borrowed iiø7-V7-i progressions (Em7b5-A7-Dm7), creating transient minor tonalities within F major.
  • Employs intricate secondary dominants and ii-V chains, exemplified by G7-Cm7-F7-Bb7, for dynamic harmonic movement.
  • Features a sophisticated “backdoor” ii-V (Bbm7-Eb7 resolving to F7), offering a chromatic approach to the tonic.
  • Showcases classic jazz turnarounds like iii-VI-ii-V-I (Am7-D7-Gm7-C7-F7) and I7-VI7-ii-V, essential for navigating the form.

Improvisation Focus: Navigating rapid chord changes with precise arpeggio outlining.

Difficulty Rating: 4/5. The frequent modulations, borrowed chords, and complex dominant functions demand advanced harmonic understanding and execution.
