Harmonic Highlights:
- Prominent interplay between D minor and its relative major, F, established by initial Fmaj7-F6 phrasing.
- Strong, altered minor iiø-V7(alt) progressions (Em7b5-A7b9/b13) consistently define the D minor tonic.
- Chromatic passing chords like Eb7/F (bVII7/I) and Eb7/Db (a tritone substitution or backdoor dominant) introduce characteristic sophistication.
Improvisation Focus: Harmonic Minor scale.
Difficulty Rating: 4 (Advanced) due to frequent altered dominants, chromatic passing chords, and sophisticated harmonic shifts.
