Harmonic Highlights:
- Establishes D minor with Em7b5 but quickly introduces modal ambiguity with Em7 and non-diatonic resolutions like Eb7 to Dmaj7.
- Features temporary tonicization of Bb major (F7b9 - Bbmaj7), followed by a chromatically descending sequence (Abm7, Gbmaj7, F7).
- The prominent Dmaj7 within a D minor context provides a Lydian sound, creating an unexpected major tonic quality.
- Frequent use of altered dominants (D7#9, F7b9) and chromatic shifts challenges traditional functional harmony.
Improvisation Focus: Chord-scale theory with an emphasis on altered dominants, chromaticism, and navigating rapid, non-functional shifts.
Difficulty Rating: 5 (Advanced) – The rapid, non-functional chord changes, frequent temporary modulations, and use of advanced harmonic devices require sophisticated theoretical knowledge and improvisational agility.
