- Consistent use of the D minor iiø7-V7 (Em7b5-A7) progression strongly establishes and reinforces the tonic.
- Features a clear secondary iiø7-V7 (Am7b5-D7b9) resolving to the subdominant minor (Gm7).
- Includes a temporary tonicization of the relative major (Fmaj7) via its ii-V (Gm7-C7) before returning to the D minor home key.
Improvisation Focus: D Harmonic Minor scale.
Difficulty Rating: 3/5. The harmony is primarily diatonic minor with clear ii-V-i progressions and a predictable secondary dominant, making it accessible but requiring understanding of minor key functional harmony.
