Harmonic Highlights:

  • Establishes F minor tonality early with Gm7b5-C7b9-Fm6, departing from the stated F major key center.
  • Features transient modulations to C major (Dm7b5-G7#5-Cmaj7) and Bb major (Cm7-F7-Bbmaj7).
  • Employs tritone substitution (Ab7) as a dominant function before Dm7b5, adding harmonic color.
  • Frequent use of minor iiø7-V7 progressions, often with altered dominants (C7b9, G7#5).

Improvisation Focus: Navigating temporary modulations and the interplay between major and minor tonalities.

Difficulty Rating: 4 - The rapid harmonic rhythm and frequent key center shifts, along with altered dominants, demand significant harmonic awareness.
