- Extensive use of altered dominant chords (e.g., C#7alt, G#7alt, Ab13b9, G7alt) creating dense chromaticism and rapid tonal ambiguity.
- Frequent half-step and tritone shifts between dominant and minor chords (e.g., E9sus-Am7 followed by Bb13) challenging diatonic expectations.
- Integration of modal interchange, particularly the bVImaj7#11 (Gbmaj7#11), which provides a bright Lydian color against the Bb minor key center.
Improvisation Focus: Altered Scale (Superlocrian).
Difficulty Rating: 5 (Advanced). The constant, complex altered dominants and rapid harmonic shifts demand sophisticated understanding and execution.
