Harmonic Highlights

  • Employs parallel chromatic descent (Dmaj7 to Gm7) using constant structures, creating a non-functional, “shifting sands” harmonic effect.
  • Prioritizes Lydian color through Maj7#11 chords, favoring bright modal textures over traditional dominant-tonic tension and resolution.
  • Utilizes abrupt modulations between distantly related keys, such as Fmaj7 to Dmaj7, bypassing standard cycle-of-fifths movement.
  • Maintains an ambiguous relationship with the G minor tonic by emphasizing major-seventh extensions and modal interchange.

Improvisation Focus Lydian Modal Shifting: Transposing the Lydian scale rapidly across non-diatonic root movements while maintaining melodic continuity.

Difficulty Rating 4/5: The combination of rapid chromatic shifts and non-functional major-seventh sequences requires advanced modal agility and sophisticated voice leading at high tempos.
