Harmonic Highlights

  • Utilizes chromatic mediant relationships and non-functional dominant resolutions, such as the shift from Gmb6 to Gbmaj7#5, creating an Impressionistic, dark tonal palette.
  • Frequent use of Lydian Augmented and #11 tensions (Ebmaj7#11, Gbmaj7#11) bypasses traditional diatonic functionality in favor of specific color-chord structures.
  • The progression oscillates between G minor tonicity and tritone substitutions (Ab7#11 to G7b9), creating intense Phrygian-dominant tension before resolving to Cm/maj7.

Improvisation Focus Melodic Minor modes (specifically Lydian Dominant and Altered scales) to navigate the dense, non-functional harmonic shifts.

Difficulty Rating 5/5 - The rapid modulation between unrelated key centers and the heavy reliance on specific chord-scale colors require advanced modal fluency and sophisticated ear training.
