Harmonic Highlights:
- Establishes D minor through the classic iiø7-V7-i progression (Em7b5-A7-Dm7).
- Features descending dominant cycles, notably D7-G7-C7, creating strong forward motion and temporary tonal centers.
- Utilizes secondary dominants like D7 (V7/G) and E7 (V7/A) to introduce chromaticism and lead into subsequent chords.
- The C7-E7-A7 progression uses a V7/V to resolve to the dominant A7, preparing the return to Dm7.
Improvisation Focus: Mastery of the D melodic minor scale and its derived modes for navigating the harmony.
Difficulty Rating: 3 (Intermediate), due to the blend of standard minor ii-V-i progressions with complex secondary dominant chains.
