Harmonic Highlights
- Frequent tonicization of F major (the bVII chord in G minor) through Gm7-C7-Fmaj7 progressions.
- Chains of ii-V progressions, exemplified by Bm7-E7-Am7-D7, creating extended harmonic motion that often resolves towards G.
- Incorporation of characteristic minor key specific harmony, such as the bVI7-V7 (Eb7-D7) cadence leading to the G minor tonic.
Improvisation Focus: Navigating diverse ii-V-I progressions and their temporary key centers.
Difficulty Rating: 4 (Advanced Intermediate) - Requires musicians to adapt to frequent modulations, extended harmonic sequences, and specific minor-key devices.
