Harmonic Highlights

  • Descending chromatic bass lines using inversions (Dm7-A7/C#-Dm7/C-G7/B) create linear voice leading through the diatonic framework.
  • Sequential ii-V movement modulates rapidly through G minor and Eb major, utilizing secondary dominants to pull back to the D minor tonic.
  • High-velocity harmonic rhythm requires navigating a “rhythm changes” inspired structure transposed into a minor modal fusion context.

Improvisation Focus D Melodic Minor and Dorian scales combined with rapid chord-tone arpeggiation to outline the fast-moving inversions.

Difficulty Rating 5/5: The extreme tempo—often exceeding 300 BPM—demands virtuosic technical facility and absolute harmonic precision to navigate the dense, shifting changes.
