Harmonic Highlights

  • Utilizes classic ii-V-I cycles in F major with frequent use of the iii-VI-ii-V turnaround (Am7-D7b9-Gm7-C7).
  • Features a sudden subdominant minor modulation to Ab major (Bbm7-Eb7b9-Abmaj7), creating a sophisticated chromatic shift away from the tonic.
  • Employs Dbmaj7 as a bVI in Ab, functioning as a pivot point to return to the primary Gm7-C7-Fmaj7 progression.
  • Navigates to the IV chord (Bbmaj7) through secondary ii-V sequences (Cm7-F7), typical of bebop-influenced jazz structures.

Improvisation Focus Voice leading through guide tones (3rds and 7ths) to connect shifting tonal centers smoothly.

Difficulty Rating 3/5; while the tempo is relaxed, the modulation to Ab major requires precise harmonic awareness beyond basic diatonic playing.
