Harmonic Highlights:
- The foundational i-iiø7-V7b9 progression (Dm-Em7b5-A7b9) establishes a strong, melancholic minor key tonality.
- A distinctive descending chromatic bass line over the tonic (Dm, Dm/maj7, Dm7, Dm6) creates a sophisticated ‘minor line cliche’.
- The E7b9 functions as a V7b9/V, providing a secondary dominant tension before resolving to the A7b9 and subsequently the D minor tonic.
- The consistent use of b9 alterations on dominant chords (A7b9, E7b9) imparts a darker, more exotic harmonic flavor.
Improvisation Focus: Harmonic Minor scale, particularly over the V7b9 chords.
Difficulty Rating: 3 (Intermediate). The altered dominant chords and the minor tonic nuances require careful scale application beyond basic major/minor understanding.
