Harmonic Highlights:
- Initial tonic prolongation with Gm6 establishes the minor key character and anticipation of harmonic movement.
- Features a iiø-V7(b9) sequence (Dm7b5-G7b9-Cm7-F7-Bbmaj7) that strongly resolves to the relative major, a common jazz idiom.
- Employs a sophisticated series of secondary iiø-V7(b9) progressions (Em7b5-A7b9, Am7b5-D7b9) to navigate intricate harmonic turns before returning to the tonic.
- The Db07 chord acts as a chromatic diminished, adding tension and colorful resolution, likely functioning as a bIIø7 of Cm7 or a passing diminished.
Improvisation Focus: Harmonic minor scale applications and related dominant altered scales.
Difficulty Rating: 4 (Advanced Intermediate) - Requires navigating complex minor iiø-V7b9 changes, temporary modulations, and chromatic alterations in various harmonic contexts.
