Harmonic Highlights:

  • Frequent use of tritone substitution resolving to minor chords (e.g., Bb7#5#9 to Ebm9).
  • Characteristic sequences of Maj7#11 chords with ascending perfect fourth root movement (e.g., C#maj7#11 - F#maj7#11 - Bmaj7#11).
  • Prevalence of highly altered dominant chords (e.g., E7#9#11, C#7#5#9) indicating advanced tension usage.
  • Strategic employment of diminished chords for chromatic voice leading and resolution to minor tonics (e.g., A#07 to Bm11).

Improvisation Focus: Lydian and Altered scales.

Difficulty Rating: 5 (Advanced). Requires deep understanding of complex chord alterations, non-diatonic resolutions, and navigating rapid harmonic rhythm with multiple temporary key centers.
