Harmonic Highlights:

  • The composition revolves around a static Bb tonic pedal point in the melody, creating varying degrees of tension against a shifting harmonic foundation.
  • Parallel chromatic descent of dominant chords (Ab7–Gb7–F7) provides a contemporary reharmonization of a standard blues-inflected progression.
  • Frequent use of tritone substitutions, such as E7b5 replacing Bb7, facilitates smooth voice leading while emphasizing Monk’s signature dissonant intervals.
  • The integration of altered dominants (G7#5, D7#5) suggests a whole-tone harmonic environment that bridges the gap between functional and non-functional tonality.

Improvisation Focus: The Bb whole-tone scale and the “Bb” pedal point concept.

Difficulty Rating: 4/5; navigating the rapid chromatic shifts while maintaining the integrity of the static melody requires advanced rhythmic precision and sophisticated tension-release management.
