Harmonic Highlights:

  • The initial Fmaj7 within the stated F minor key center highlights significant modal mixture, borrowing from the parallel F major.
  • Ab07 (likely functioning as Bdim7 or vii°7/C) leads to Gm7 C7, showcasing a sophisticated secondary diminished chord resolving to the dominant preparation.
  • An extended Bbm7 Eb7 -> Abmaj7 section establishes a clear modulation to Ab major, the relative major of F minor.
  • The consistent use of ii-V progressions in both F minor (implied) and Ab major creates strong functional harmony throughout the form.

Improvisation Focus: Fluidly transitioning between F minor and Ab major tonalities, employing respective minor (harmonic/melodic) and major scale forms.

Difficulty Rating: 4 (Upper Intermediate) Involves modal mixture, secondary diminished chords, and a significant modulation to the relative major, requiring harmonic agility.
