Harmonic Highlights:
- Utilizes sequential, half-step descending ii-V progressions, exemplified by F#m7-B7 leading to Fm7-Bb7.
- Features clear modulation to the parallel major (Am7-D7-Gmaj7) within the G minor framework.
- Employs dominant suspensions (Fm7/Bb functioning as Bb7sus4) resolving to temporary Eb major tonicizations.
- Incorporates sophisticated chromatic minor ii-V movements (e.g., Gm7b5-C7b9), indicating complex temporary key centers.
Improvisation Focus: Navigating rapid, sequential ii-V changes and frequent temporary modulations.
Difficulty Rating: 5 (Advanced) due to the rapid harmonic rhythm, frequent chromatic ii-V sequences, and constant temporary modulations demanding adaptable scale and arpeggio choices.
