Harmonic Highlights

  • Frequent use of Lydian structures (maj7#11) and slash chords like Abmaj7#11/G creates a “floating” tonality that avoids traditional V-I cadences.
  • The progression utilizes chromatic tritone substitutions (A7alt to Abmaj7#11) and rapid shifts to distant key centers like Bm and Gmaj7.
  • Use of “upper structure” slash chords (F/G) functions as suspended dominant colors, blending multiple harmonic functions into single, dense sonorities.

Improvisation Focus Modal interchange and Lydian scale fluency across rapidly shifting tonal centers.

Difficulty Rating 4/5 – Navigating the non-functional movement and constant modulations requires advanced melodic control and deep knowledge of specific chord extensions.
