Harmonic Highlights

  • Incorporates non-functional ii-V transitions (Am7-D7 to Abmaj7) and chromatic mediant movement (Cmaj7 to Abmaj7) to destabilize the B major center.
  • Employs “constant structures” via parallel major 7th and minor 9th chords, creating a floating, ethereal modal texture characteristic of fusion-era harmony.
  • Features a chromatic descending resolution (Em9 to Ebm7 to Dmaj7) that bypasses traditional circle-of-fifths logic in favor of smooth linear voice-leading.

Improvisation Focus Navigating “constant structure” modulations and utilizing the Lydian mode over non-functional major 7th chords.

Difficulty Rating 4: The frequent, rapid shifts between distantly related keys require high-level modal fluency and sophisticated harmonic mapping.
