Harmonic Highlights:

  • Begins with extended tonicization of C major (relative major) via ii-V-I progressions (e.g., Dm7b5-G7b9-Cmaj7), delaying the primary A minor key center.
  • Features descending ii-V-I modulations, notably to F major (bVI of A minor) before establishing the Am tonic (Bm7b5-E7-Am).
  • Utilizes characteristic minor iiø-V progressions for both the tonic and secondary keys, like Em7b5-A7b9 (iiø-V of D minor).
  • The Bm7-E7 before Am suggests parallel major borrowing, adding a dorian-like color to the dominant approach.

Improvisation Focus: A Harmonic Minor scale and its derived modes (e.g., Phrygian Dominant for V7 chords), adaptable for diverse ii-V resolutions across shifting tonal centers.

Difficulty Rating: 4 (Advanced Intermediate) Frequent modulations and sophisticated minor-key harmony, including altered dominants, demand a strong grasp of functional harmony and modal applications.
