  • Frequent use of non-functional chromatic dominants and side-slipping movements (e.g., F#maj7 to G7#11).
  • Abrupt major third modulations (Amaj7 to Cmaj7) and subsequent whole-step shifts (Cmaj7 to Dmaj7).
  • Extensive deployment of tritone substitutions within II-V progressions, facilitating remote key transitions (e.g., Ab7alt - Db7alt resolving to Cmaj7).
  • Dramatic, unheralded shifts to distant key centers, as seen with the sudden appearance of Bbm.

Improvisation Focus: A deep understanding and agile application of altered dominant scales (Super Locrian) to navigate the numerous altered tensions and remote modulations.

Difficulty Rating: 5 (Advanced) - The piece demands exceptional harmonic flexibility due to constant, often non-diatonic, modulations and complex altered dominants.
