Harmonic Highlights:
- Opens with a classic I-VI-II-V progression (Gmaj7-Em7-Am7-D7) in the home key of G major.
- Features a clear modulation to the subdominant (C major) via a II-V-I sequence (Dm7-G7-Cmaj7).
- Employs sophisticated secondary iiø7-V7 progressions (e.g., C#m7b5-F#7) to temporarily tonicize the relative minor (Bm7).
- Incorporates a borrowed chord (Cm6), providing a minor iv sound for harmonic color.
Improvisation Focus: Precise navigation of temporary modulations using chord-tone arpeggios and appropriate altered scales over secondary dominants.
Difficulty Rating: 4 (Advanced Intermediate). The frequent temporary modulations, borrowed chords, and secondary dominants demand strong harmonic awareness and agility from the improviser.
