Harmonic Highlights

  • Employs static Lydian structures (Dbmaj7#11, Abmaj7#11, Gbmaj7#11) that emphasize the #11 tension, a hallmark of Henderson’s post-bop modal vocabulary.
  • Features a chromatic “side-slip” transition from Dbmaj7#11 to Cm7, subverting functional V-I cadences in favor of direct, non-functional modal juxtaposition.
  • Utilizes non-functional planing, shifting Maj7#11 sonorities across various tonal centers to create atmospheric textures rather than traditional diatonic resolutions.

Improvisation Focus The Lydian mode (specifically Db, Ab, and Gb Lydian) is the primary vehicle for navigating the static harmonic blocks and highlighting the #11 color.

Difficulty Rating 3/5; the slow harmonic rhythm provides ample time for note choice, but the non-functional leaps require a sophisticated ear for modal shifts and specific scale colors.
