Harmonic Highlights:
- Frequent descending chromatic dominant 7#11 sequences (e.g., F7#11, E7#11, Eb7#11, D7#11), generating polytonal tension and rapid shifts.
- Non-diatonic major 7th chords like Cmaj7, Fmaj7, and Dbmaj7#11 introduce unexpected chromatic colors and temporary tonal centers.
- Abrupt, non-functional dominant chord movements (e.g., Db7, Gb7) lead to distant harmonic areas without typical ii-V-I resolutions.
Improvisation Focus: Emphasis on chromaticism and precise chord tone targeting amidst rapid harmonic shifts.
Difficulty Rating: 5 (Advanced). Its dense, non-functional chromaticism and varied altered chord qualities demand exceptional harmonic and melodic agility.
