Harmonic Highlights

  • Rapid shifts through distantly related key areas (Ab Maj, B Maj, E Maj) via non-functional dominant and major seventh chords.
  • Frequent use of 7sus and #11 extensions to create harmonic ambiguity and avoid traditional tension-resolution cycles.
  • Utilization of chromatic “planing” and tritone-related movements to bridge disparate harmonic cells.
  • A circular 16-bar structure that avoids a final tonic resolution, favoring a perpetual loop back to the beginning.

Improvisation Focus Melodic development and rhythmic displacement over non-functional harmony.

Difficulty Rating 5/5: The lack of standard II-V-I cadences and the constant shifting of unrelated tonal centers require advanced harmonic awareness and melodic phrasing.
