Harmonic Highlights

  • Side-slipping resolution: The recurring Cmaj7 to Db7 movement utilizes chromatic neighbor-tone harmony, creating the “out” sound characteristic of Monk’s writing.
  • Functional V-of-IV: The sequence of Gm7 to C7 leading into F7sus acts as a ii-V-I to the subdominant, providing a brief blues-based structural anchor.
  • Abrupt tonal displacement: The transition from C13 and A7 to Dmaj7 represents a sudden shift to the II major key, defying standard diatonic expectations.

Improvisation Focus The Whole-Tone scale and side-slipping melodic motifs.

Difficulty Rating 4/5: The non-functional chromaticism and irregular rhythmic phrasing require advanced harmonic navigation and a strong internal pulse.
