Harmonic Highlights:
- The harmony primarily establishes a D minor tonality (Dm6 as tonic), despite the stated D major key center, lending a melancholic and Spanish character.
- Features frequent minor iiø7-V7-i progressions, exemplified by Am7b5-D7b9-Gm6 (tonicizing G minor) and Bm7b5-E7b9-A7b9 (leading to the primary dominant).
- The D7b9 -> Em7b5 progression demonstrates a deceptive resolution of a secondary dominant (V7/iv) before resolving into a standard iiø7-V7-i of D minor.
- Prominent use of b9 extensions on dominant chords (D7b9, A7b9, E7b9) consistently provides a characteristic dark, exotic tension.
Improvisation Focus: Phrygian Dominant mode over V7b9 chords to emphasize the characteristic minor key tension.
Difficulty Rating: 4 (Advanced) – Navigating frequent minor key ii-V-i progressions, deceptive harmonic movements, and specific altered dominant voicings requires advanced harmonic understanding and scale application.
