Harmonic Highlights:
- Prominent use of the minor iiø-V7b9-i progression (Em7b5 - A7b9 - Dm7) effectively establishes the D minor tonality.
- Temporary tonicization of the relative major (Fmaj7) is achieved through a clear ii-V-I progression (Gm7 - C7 - Fmaj7).
- A distinctive chromatic dominant movement occurs from Bb7#11 (bVI7alt) to A7#11 (V7alt), adding tension and unique color before resolving to the tonic.
Improvisation Focus: D Harmonic Minor, particularly over the A7b9 and for emphasizing the minor tonality.
Difficulty Rating: 3 (Intermediate) - Requires navigating standard minor key ii-V-i changes, temporary modulations, and altered dominant chords.
