Harmonic Highlights

  • Features recurrent ii-V-I progressions, frequently resolving to bIII (Abmaj) and the tonic minor (Fm).
  • Incorporates secondary ii-V structures (Am7-D7 to Gm) that temporarily shift the tonal center.
  • Exhibits a major tonic resolution (Fmaj7, F6) within an F minor context, suggesting a mixed mode or Picardy third approach.
  • Modulates effectively to the bVI major (Dbmaj7) via its dominant ii-V (Ebm7-Ab7).

Improvisation Focus: Navigating ii-V-I progressions across shifting tonalities.

Difficulty Rating: 4 (Advanced Intermediate). The frequent modulations, minor key complexities, and mixed tonic qualities demand strong harmonic awareness and scale flexibility.
