Harmonic Highlights

  • Employs rapid ii-V-I modulations that shift tonal centers every two beats, starting with a minor ii-V resolving to a major tonic (Ebm7b5โ€“Ab7b9โ€“Dbmaj7).
  • Features a deceptive chromatic descent of dominant 7th chords (F7โ€“Bb7โ€“A7โ€“Ab7โ€“G7) which prioritizes linear motion over functional circle-of-fifths resolution.
  • Utilizes pivot chords to bridge distant keys, such as shifting from the Db major landscape into E major via F#m7โ€“B7.

Improvisation Focus Continuous voice-leading and guide-tone navigation through rapid-fire changes.

Difficulty Rating 5/5 โ€” The extreme harmonic density and erratic modulations require an advanced command of bebop vocabulary and instant mental transposition.
