Harmonic Highlights:

  • Features descending whole-step modulations (Gmaj7 to Fmaj7, Fmaj7 to Ebmaj7) in a signature “bridge” movement.
  • Incorporates sophisticated minor ii-V-i progressions (Am7b5-D7b9-Gm7), temporarily tonicizing the parallel minor.
  • Utilizes a blend of major and minor-related ii-V changes, including Am7b5-D7b9 resolving to both Gm7 and Gmaj7.
  • Employs sequential ii-V progressions (e.g., Am7-D7, Bm7-E7) to build tension and lead through different harmonic areas.

Improvisation Focus: Navigating rapid modulations and adapting scales/arpeggios to transient key centers.

Difficulty Rating: 4 (Advanced). The tune demands quick harmonic recognition and the ability to fluidly outline chord changes across multiple key centers.
