Harmonic Highlights

  • Chromatic descending root movement (Amaj7–Abm6–Gmaj7–F#7b9) serves as a sophisticated prolongational path to the VI dominant (F#7).
  • Non-functional “constant structure” shifts (Gm7–F#m7–Fm7) create a sliding modal landscape that avoids traditional cycle-of-fifths resolutions.
  • The use of Gmaj7#11 and G#7sus highlights Corea’s signature “Lydian” aesthetic, prioritizing color and tension over standard diatonic function.
  • Strategic ii-V sequences, such as Em7–A7 leading to Dmaj7, provide brief moments of tonal stability before returning to chromatic side-slipping.

Improvisation Focus Lydian and Lydian Dominant modal shifting.

Difficulty Rating 4. The rapid, non-functional chromatic modulations and shifting tonal centers require advanced ear training and high-level scalar agility.
