- Initial use of non-diatonic Amaj7 and Gmaj7 creates a Lydian-esque, floating quality, moving away from a strict G minor diatonicism.
- Features a clear, albeit chromatic, modulation to C Major via a Dm7b5-G7b9-Cmaj7 ii-V-I progression, with an unexpected Dbm7 pre-dominant.
- Incorporates a distinct modulation to Eb Major through a functional Cm7-Bb7-Ebmaj7 ii-V-I progression, demonstrating substantial harmonic movement.
- The major-to-minor tonic shift (Cmaj7 to Cm7) adds a classic jazz harmonic color and sets up subsequent dominant motion.
Improvisation Focus: Chord-scale theory applied to the frequently shifting local key centers.
Difficulty Rating: 5 (Advanced) - Its frequent, non-diatonic modulations and complex chord alterations demand advanced harmonic understanding and improvisational agility.
