Harmonic Highlights:
- Employs clear ii-V-I progressions establishing Bb major as the tonic.
- Features a significant modulation to Gb major through a ii-V-I (Ebm7-Abm7-Db7-Gbmaj7), representing a tritone away from the home key.
- Utilizes secondary ii-V progressions (e.g., Dm7-G7 for Cm7, Gm7-C7 for F major) to expand harmonic movement.
- Incorporates chromatic passing chords like Eb7 and Dbm7 for added harmonic color and tension.
Improvisation Focus: Navigating ii-V-I changes and targeting chord tones across multiple, sometimes distant, key centers.
Difficulty Rating: 4/5. The frequent modulations to distant keys, particularly Gb major, demand advanced harmonic awareness and quick adaptation.
