Harmonic Highlights

  • Extensive use of parallel harmonic motion (planing), moving m9 and maj9 structures chromatically (Bbm9 to Am9) to create a fluid, shifting tonal landscape.
  • Non-functional chord progressions, such as the juxtaposition of Gbmaj9 and Em69, which prioritize voice leading and color over traditional diatonic resolution.
  • A complex turnaround utilizing Dm7b9 to G7#5#9 followed by Cø7 to B7alt, providing a highly dissonant, altered pathway back to the tonic center.

Improvisation Focus Modal Planing: Navigating rapid, non-diatonic shifts by identifying the specific mode for each chord (predominantly Dorian and Lydian) while maintaining melodic continuity through voice leading.

Difficulty Rating 4 (Advanced): The lack of a consistent key center and the prevalence of non-functional, “sidestepping” harmony require high-level navigation skills and sophisticated ear training beyond standard bebop vocabulary.
