Harmonic Highlights

  • Monk utilizes a sequence of dominant cycles (Ab7–Db7–Gb7) that subverts traditional functional expectations, creating a bluesy, chromatic descent away from the tonic.
  • The movement from F7b9 to Bm7–E7 demonstrates a sudden shift to a distant tonal center (A), showcasing Monk’s signature use of tritone relationships and side-slipping.
  • The frequent use of dominant 7#11 and b9 alterations facilitates a bridge between Ab major tonality and the whole-tone scale.
  • The coda employs a dominant pedal (Eb) with moving triads (Ab/Eb, Bbm/Eb), providing a stable anchor against the preceding harmonic density.

Improvisation Focus The Whole-Tone scale and thematic development of the melody’s specific rhythmic fragments.

Difficulty Rating 4/5; the through-composed nature and specific, idiosyncratic voicings require a high level of harmonic precision and mastery of rubato phrasing.
