Harmonic Highlights

  • Features a suspended “side-slipping” motion (Eb7sus to Ab7sus), shifting the tonal center through parallel dominant structures rather than traditional functional harmony.
  • Employs a bVI-V turnaround (Dbmaj7 to C7) that anchors the abstract modal sections back to a traditional minor blues logic.
  • Uses a persistent Eb7#9/F pedal, creating a dissonant, polytonal texture that establishes the high-tension “hurricane” aesthetic.

Improvisation Focus F Dorian mode and the Minor Blues scale.

Difficulty Rating 4/5. The high-speed tempo and the requirement to navigate between static “sus” chords and functional minor turnarounds demand advanced technical facility and harmonic clarity.
