Harmonic Highlights:

  • Frequent chromatic “planes of sound” parallelism (e.g., Bbm9-Am9, Fm9-Ebm9).
  • Abrupt half-step modulations (Bbm7-Bmaj7) and striking non-functional chords (e.g., Db/A).
  • Extensive use of altered dominants (G7#5#9, B7alt) and diminished chords (C0) for continuous tension.
  • Sequential descending major/minor 9th chord movements (e.g., Gbmaj9-Em69-Dmaj9) for fluid harmonic shifts.

Improvisation Focus: Fluid application of altered scales and melodic minor modes to navigate the rapid, non-diatonic shifts.

Difficulty Rating: 5 (Advanced). The extremely rapid, non-functional harmonic rhythm with extensive altered chords demands high-level ear training and technical proficiency.
