Harmonic Highlights

  • Employs tritone substitutions, such as A7#11 leading to Abmaj7, replacing the traditional Eb7 to create sophisticated chromatic tension.
  • Features chromatic side-slipping with the Gm7 - Gb7 - Fm7 sequence, reharmonizing the standard iii - VI - ii - V progression with parallel movement.
  • Incorporates non-functional dominant cycles (E7#9#11 to Db7#11), shifting the tonal center rapidly through distant keys typical of post-bop reharmonization.

Improvisation Focus Mastery of the Lydian Dominant scale and chromatic voice leading to navigate non-resolving dominant 7th chords.

Difficulty Rating 4/5: The rapid-fire chromatic substitutions and non-diatonic shifts require advanced harmonic fluency and precise ear-to-instrument connection.
