Harmonic Highlights

  • Parallel chromatic descent of dominant 7th chords ($F7^{#11}$ down to $D7^{#11}$) showcases Monk’s signature “sideslipping” motion, creating tension through non-functional harmonic planning.
  • The composition opens on a $Cmaj7$, acting as a $\flat VI$ in the E major tonic, which obscures the tonal center and subverts traditional functional expectations.
  • Frequent use of $#11$ extensions on both dominant and major chords reinforces a consistent Lydian and Lydian Dominant harmonic color throughout the progression.
  • Strategic use of tritone substitutions, particularly the $Db7$ to $Gb7$ movements, facilitates smooth voice leading despite the angular melodic intervals.

Improvisation Focus The Lydian Dominant scale and its related Whole Tone applications to navigate the sequence of altered dominant chords.

Difficulty Rating 4/5: The rapid chromatic shifts and non-diatonic chord relationships require advanced knowledge of substitution theory and precise melodic targeting.
