Harmonic Highlights:
- Prominent use of symmetrical minor 7th cycles (e.g., Bbm7-Dbm7-Em7-Gm7), creating intervallic rather than traditional functional progressions.
- Extensive non-functional chromaticism with roots moving by consistent intervals (e.g., minor 3rds, major 3rds, tritones) throughout the form.
- Brief, localized V-i resolutions (e.g., A7b9-Dm7, D7#9-Gm7) punctuate the otherwise ambiguous and rapidly shifting tonal centers.
Improvisation Focus: Symmetrical scales (e.g., diminished, augmented) and a highly sophisticated chord-scale approach to navigate the dense chromaticism.
Difficulty Rating: 5 (Advanced). The constant, non-functional harmonic shifts demand a highly developed ear and the ability to instantly adapt to new, often fleeting, tonal landscapes.
