Harmonic Highlights

  • Utilizes chromatic planing (F#9b5 to F9b5) to create a non-functional, impressionistic “shimmer” rather than standard tonic-dominant resolution.
  • The progression employs “side-slipping” and tritone-related modulations, shifting from G minor to a distant Db major bridge via descending Lydian Dominant chords.
  • Relies on sophisticated voice leading where altered extensions—specifically b13, #11, and b5—guide the melody through a dense, non-diatonic landscape.

Improvisation Focus The Lydian Dominant scale is the primary tool for navigating the predominant 7#11 and 9b5 structures found throughout the form.

Difficulty Rating 4/5. The lack of standard II-V-I patterns and the frequency of chromatic shifts require advanced harmonic awareness and precise melodic targeting.
