Harmonic Highlights

  • The composition utilizes frequent tritone substitutions and symmetrical movements, such as the opening Bbmaj7#11 (substituting for the V) resolving toward E7alt, creating a tension-rich entry into the E major tonal center.
  • Wheeler employs dense minor ii-V sequences (Dm9 to E7b9b13 to Am7) that create a dark, minor-key gravity, momentarily obscuring the primary major key center.
  • Parallelism and constant structure shifting are evident in the Cm11–Dm11–Em11 sequence, demonstrating Wheeler’s signature “floating” harmonic style that avoids traditional functional cadences.
  • Specific chord inversions and slash chords, such as C/G to E7b13/G#, facilitate smooth, stepwise bass motion through highly chromatic and distant tonal shifts.

Improvisation Focus Melodic Minor modes (specifically Lydian Dominant and Altered scales) to navigate the rapid, non-diatonic dominant extensions.

Difficulty Rating 4/5. The frequent non-functional modulations and specific altered tensions require advanced harmonic awareness and precise melodic voice leading.
