Harmonic Highlights:

  • The opening Fm, Ebm7, Ab7, Dbmaj7 progression establishes a sophisticated harmonic move, featuring a ii-V-I resolving to the bVI major, implying modal interchange or a backdoor dominant approach.
  • The piece frequently employs standard ii-V-I progressions in both the tonic (Gm7b5-C7b9-Fmaj7) and its relative minor (Em7b5-A7b9-Dm).
  • Prominent altered dominant chords (C7b9, A7b9) introduce significant harmonic tension and color before their resolutions.
  • The harmony frequently modulates or oscillates between F major and its relative minor, D minor, providing contrast.

Improvisation Focus: Accurate chord-tone outlining across the functional harmony.

Difficulty Rating: 4 (Advanced Intermediate). The rapid chord changes, frequent modulations, and use of altered dominants demand a strong understanding of harmonic function and melodic adaptability.
