Harmonic Highlights:
- Initial tonicization of the relative minor (Fmaj7 to Em7b5-A7b9-Dm7).
- Cascading ii-V-I modulations to Bbmaj7 then Abmaj7, creating descending harmonic shifts.
- Prominent use of altered dominants (e.g., A7b9, F7b9, Eb7b9, C7b9) and minor iiø7 chords.
- Significant modulation to Db major via Ebm7-Ab7-Db6, showcasing chromatic harmonic exploration.
Improvisation Focus: Chord-scale navigation, particularly targeting altered dominants and minor ii-V changes.
Difficulty Rating: 4 (Advanced Intermediate) - Frequent modulations, numerous ii-V progressions, and altered dominant chords demand agile harmonic adaptability.
