Harmonic Highlights

  • The progression utilizes recurring minor ii-V patterns (Am7b5-D7b9 and Gm7b5-C7b9) to create a dark, chromatic approach toward the F major tonic.
  • Subdominant movements are emphasized through the Bb7#5#9 and Bb13b9, showcasing Monk’s preference for dominant substitutions and altered extensions.
  • The bridge features a persistent Cm7b5-F7b9 sequence, creating a prolonged tension on the ii-V of the IV chord.

Improvisation Focus Altered Dominant scales (Super Locrian) and the Whole-Tone scale to navigate Monk’s dissonant voice leading.

Difficulty Rating 4/5. Navigating the dense minor ii-V cycles within a major key requires advanced modal fluency and mastery of chromatic tension-resolution patterns.
