Harmonic Highlights

  • The tune opens with a parallel minor tonicization (Fm) leading into a bVI (Dbmaj7) via a ii-V (Ebm7-Ab7), showcasing sophisticated sub-dominant minor substitutions.
  • Extensive use of minor ii-V-i sequences (Em7b5-A7b9-Dm) creates a somber, shifting tonal center between F Major and its relative D Minor.
  • Transitions back to the F major tonic utilize Gm7b5-C7b9, employing dominant-minor functional harmony to resolve chromatic tension.

Improvisation Focus Melodic Minor applications over minor ii-V progressions.

Difficulty Rating 4/5: Navigating the constant flux between F major and the flattened submediant (Db) requires advanced knowledge of minor-key harmony and precise voice leading.
