Harmonic Highlights

  • Employs parallel minor 9th chords (Am9 to Gm9) to establish a somber, modal D minor foundation.
  • Incorporates sequential Imaj7 to IV7#11 pairings that shift via major thirds (A to Db) and whole steps (Db to B).
  • Bridges modal sections with functional ii-V turnaround chains, creating a sophisticated blend of hard bop and modern jazz vocabulary.
  • Utilizes the #11 extension on dominant chords to provide a bright, Lydian-inflected color against the darker minor tonic.

Improvisation Focus

  • Lydian Dominant scale applications over the recurring IV7#11 chords.

Difficulty Rating

  • 4/5: The constant modulation between unrelated key centers and reliance on upper-structure extensions require advanced harmonic awareness and rapid melodic transposition.
