Harmonic Highlights:
- Frequent modal interchange occurs with the early shift from Gmaj7/G6 to Gm7/Gm6, borrowing from the parallel minor.
- A chain of iiø-V7b9 progressions (Am7b5-D7b9, Bm7b5-E7b9) creates a sense of chromatic tension and temporary tonal centers before returning to the home key’s ii-V.
- A clear, strong modulation to Bb major is presented through a concise Cm7-F7-Bbmaj7 ii-V-I progression, departing from the home key of G major.
Improvisation Focus: Navigating chord tones and arpeggios across the frequent ii-V changes and modal shifts.
Difficulty Rating: 4 (Advanced Intermediate). The rapid modulations, altered dominants, and parallel major/minor shifts demand strong harmonic awareness and agility.
