Harmonic Highlights:
- Frequent use of highly altered dominant chords (e.g., A7#5#9, D7#9, E7#9) creating intense chromatic tension and advanced voice leading.
- Non-diatonic root movements and modal interchange, exemplified by the Bbmaj7 to Abm7 progression, defying simple functional harmony.
- Extensive application of suspended and altered dominant chords (D7b9sus, G7b9sus, C13b9) to prolong tension and add complex harmonic color.
Improvisation Focus: Navigating altered scales (Super Locrian, Lydian b7) over complex dominant voicings.
Difficulty Rating: 5 (Advanced). The sophisticated use of altered harmony, non-functional progressions, and rapid chord changes requires deep theoretical and practical mastery.
