Harmonic Highlights

  • Uses constant structure motion and parallel major chords (G-A-Bmaj7) that defy traditional functional cadences.
  • Employs chromatic “side-slipping” transitions, such as Bmaj7 to Cmaj7#11, to create tension and unexpected modal shifts.
  • Features a sudden transition to an extended E Lydian pedal point (Emaj9#11), providing a static modal contrast to the earlier harmonic density.

Improvisation Focus Lydian and Lydian Augmented scales applied to non-functional major seventh and dominant structures.

Difficulty Rating 5/5. The rapid movement through unrelated keys and non-diatonic extensions demands advanced mastery of modal interchange and melodic connectivity.
