Harmonic Highlights:
- Features heavily altered dominant chords (D7#9, G7#5, C7#9, D7b9) often leading to unexpected or non-diatonic resolutions.
- Incorporates repeated non-diatonic II-V sequences like Ebm7-Ab7, creating frequent, brief modulations to remote tonal centers (e.g., Db major).
- Exhibits unpredictable dominant shifts, such as G7#5 to Gb7, utilizing tritone substitution and chromatic movement rather than standard V-I.
Improvisation Focus: The Melodic Minor scale (and its modes) is essential for navigating the complex altered dominant and various minor chord qualities.
Difficulty Rating: 5 (Advanced) due to the rapid harmonic rhythm, frequent modulations, and extensive use of altered chord voicings demanding high proficiency.
