Harmonic Highlights:
- Features a predominant cycle of V7-i minor progressions, often descending chromatically (e.g., Bm7-E7-Am7, Gm7-C7-Fm7, Fm7-Bb7-Ebm7).
- Frequent use of non-diatonic dominant 7th chords creates sudden, distant modulations, often moving by major or minor third relationships (e.g., Ebm7 to E7, or Gb7).
- The progression emphasizes rapid harmonic rhythm and constant key center shifts, challenging the improviser to navigate multiple transient tonalities.
Improvisation Focus: Arpeggio outlining and strategic scale superimposition (e.g., altered dominant, melodic minor) to navigate rapidly shifting chord progressions.
Difficulty Rating: 5 (Advanced) The relentless, chromatically descending V7-i minor cycles and sudden, distant modulations demand sophisticated harmonic awareness and technical facility.
