Harmonic Highlights

  • Employs a sophisticated 12-bar blues variant utilizing a minor ii-V ($Gm7\flat5$ - $C7\flat5\flat9$) as a secondary leading progression to the $Cm7$ (ii).
  • Integrates Monk’s signature altered dominant extensions ($Bb7\flat5$, $C7\flat5\flat9$), which emphasize tritone dissonances and symmetrical scale logic.
  • Features a chromatic turnaround sequence that transitions from the tonic to the ii-V-I cadence through heavy use of secondary dominants and flattened fifths.

Improvisation Focus The Whole-Tone scale (specifically utilized over the altered dominant chords to capture the signature Monk harmonic aesthetic).

Difficulty Rating 3/5; while the underlying blues structure is foundational, the specific altered extensions and angular voice-leading demand precise harmonic accuracy and stylistic nuance.
