Harmonic Highlights:
- Establishes a core D minor tonality through recurring i-iiø-V7b9 progressions (Dm6, Em7b5, A7b9).
- Features clear modulations, including a iiø-V-i progression to G minor (iv) via Am7b5, D7b9, Gm7.
- Employs frequent secondary ii-V cycles, such as Bm7-E7 (targeting A minor) and Gm7-C7-Fmaj7 (targeting F major).
Improvisation Focus: Navigating frequent ii-V progressions across various temporary key centers.
Difficulty Rating: 4 (Advanced) – The rapid harmonic rhythm and numerous modulations require a strong grasp of secondary dominants and temporary key centers.
