Harmonic Highlights

  • Features a rapid descent of dominant 7th chords (Ab7–Db7–Gb7–B7–E7) that utilizes the cycle of fourths to create intense harmonic motion before resolving back to the tonic.
  • Employs frequent tritone substitutions, notably the A7#11 acting as a chromatic bridge between the Eb7 and the Ab7.
  • Utilizes altered ii-V-I cells (Bbm7–Eb7#11 and Fm7–Bb7#5) to provide Monk’s signature dissonant “crunch” within a standard Eb major framework.

Improvisation Focus Angular arpeggio-based cells and rhythmic displacement over the Eb Mixolydian/Bebop scale.

Difficulty Rating 5/5. The extreme tempo combined with jagged, wide-interval melodic leaps and rapid-fire chord substitutions requires elite technical facility and harmonic timing.
