Harmonic Highlights

  • Employs an initial C major turnaround (I-vi-ii-V) that serves as a launchpad for dense, sequential modulations.
  • Features a sophisticated tritone-related shift from Bb7 directly to Emaj7, creating a high-tension harmonic pivot point.
  • Utilizes descending ii-V-I sequences (moving from Eb major to D major) that require rapid tonal center shifts every two measures.

Improvisation Focus Navigating rapid ii-V-I sequences through diverse key centers using smooth voice leading and guide tones.

Difficulty Rating 4/5. The relentless tempo and frequent, non-diatonic modulations demand advanced harmonic navigation and mental agility from the soloist.
