Harmonic Highlights:
- Features descending whole-step modulations via ii-V progressions, moving from Gmaj7 to Fmaj7 (via Gm7-C7) and then to Ebmaj7 (via Fm7-Bb7).
- Frequent use of
Am7b5 - D7b9(iiø-V7b9) which often targets G minor but resolves both to minor (Gm7) and major (Gmaj7) tonics. - Employs extended turnarounds, combining classic
iii-VI-ii-Vcycles (e.g., Bm7-Em7-Am7-D7) with altered minor ii-V progressions.
Improvisation Focus: Arpeggio superimposition to precisely outline rapid, dense chord changes and their extensions.
Difficulty Rating: 5 (Advanced) due to the fast harmonic rhythm, frequent modulations, and use of altered dominants requiring sophisticated navigational skills.
