  • Features rapid tonicization, cycling through three major keys (B, Eb, G) whose roots are a major third apart.
  • Each major key is momentarily established via a V7-I resolution (e.g., F#7-Bmaj7, Bb7-Ebmaj7, D7-Gmaj7).
  • The progression constantly shifts tonal centers, creating a sense of unrelenting forward motion and avoiding a single stable tonic.

Improvisation Focus: Arpeggios (and their derived scales) of each quickly changing chord are essential to outline the dense harmonic rhythm.

Difficulty Rating: 5 (Advanced) Its extremely fast harmonic rhythm and constant modulation through distantly related keys demand exceptional technical and theoretical proficiency.
