Harmonic Highlights:

  • Prominent use of diatonic II-V-I progressions in F major.
  • Temporary tonicization of the subdominant (Bbmaj7) through a II-V (Cm7-F7).
  • Inclusion of a Bb7#11 chord, offering a Lydian dominant sound or bluesy alteration.
  • Chromatic passing diminished Ab07 providing tension and voice leading between Am7 and Gm7.

Improvisation Focus: F Major Scale and its diatonic modes (Dorian for minor, Mixolydian for dominant).

Difficulty Rating: 3 (Intermediate). The tune features standard II-V-I changes but introduces a brief modulation and a few colorful altered chords, requiring careful navigation beyond basic scales.
