Harmonic Highlights:
- Rapid descending major third modulations are evident, moving from Gmaj7 to Fmaj7, and then implied towards Eb (Fm7-Bb7-Eb6).
- Prominent use of altered dominant chords (A7b9, D7b9) generates significant harmonic tension and dramatic resolution.
- The progression features an interplay of both major and minor ii-V-I structures to establish transient key centers.
- Standard ii-V-I turnarounds (Bm7-Em7-Am7-D7) anchor the progression back to the G major key center.
Improvisation Focus: Accurate chord-tone improvisation, precisely outlining each transient modulation and altered dominant.
Difficulty Rating: 5 (Advanced). The dense, non-diatonic harmonic shifts and frequent altered dominant voicings require a sophisticated understanding and execution.
