- Extensive use of chromatic dominant approaches (Gb7, G7) creating immediate tension and harmonic ambiguity.
- Rapid, extensive sequences of descending II-V progressions (e.g., Bm7-E7, Bbm7-Eb7), modulating quickly through multiple remote key centers.
- Frequent harmonic motion far outside the established B minor key, employing non-diatonic resolutions and altered dominants.
Improvisation Focus: Mastery of arpeggios and altered dominant scales to outline rapidly changing chord qualities across diverse key centers.
Difficulty Rating: 5 (Advanced) Requires exceptional harmonic fluidity and the ability to articulate complex, non-diatonic chord changes at speed.
