Harmonic Highlights
- Prominent use of the minor iiø7-V7b9-i progression resolving to both the tonic (Am7b5-D7b9-Gm) and the subdominant (Dm7b5-G7b9-Cm).
- Frequent application of V7b9 chord quality (D7b9, G7b9, A7b9), generating strong tension-resolution throughout the form.
- Incorporates secondary dominant function with G7b9 (V7/iv) leading to Cm and A7b9 (V7/v) leading to Dm, expanding harmonic movement.
Improvisation Focus: G Harmonic Minor scale and its associated modes (e.g., Phrygian Dominant for V7b9 chords).
Difficulty Rating: 3. Navigating the specific minor ii-V-i resolutions and the secondary dominant chords requires a solid understanding of minor key harmony.
