Harmonic Highlights

  • Frequent use of modal interchange and chromatic “side-slipping” between distantly related minor tonalities (Gm, Em7b5, Dm7) to create a refracted, prismatic effect.
  • Integration of secondary ii-V sequences (F#7b9–Bm7, E7b9–Am) that provide brief functional anchors within an otherwise non-functional, modal landscape.
  • Tertiary root relationships and sudden shifts to major sonorities (Fmaj7, Cmaj7) which offer bright contrast to the dark, minor-heavy harmonic palette.

Improvisation Focus Melodic Minor and its modes (specifically Altered and Lydian Dominant) for navigating the dense, shifting minor extensions.

Difficulty Rating 4: The non-traditional modulations and lack of a constant tonal center require advanced harmonic navigation and modal fluidity.
