Harmonic Highlights:
- Frequent V7sus-V7 resolution (D7sus-D7) firmly establishes G major as the tonic.
- Features an early ii-V-I (Dm7-G7-Cmaj7) briefly modulating to C major.
- Undergoes a strong modulation to Bb major with a clear Cm7-F7-Bbmaj7 ii-V-I.
- The subsequent Bbm7 implies further non-diatonic movement or a temporary minor key.
Improvisation Focus: Navigating clear modulations by targeting chord tones and guide tones in each new key center.
Difficulty Rating: 4 (Advanced Intermediate). The rapid, distinct modulations to non-related keys require quick harmonic adaptation.
