  • Extensive use of dominant cycles (Bb7-Eb7-Ab7-Db7-Gb7) and secondary dominants.
  • Signature Monk half-step modulations and slides (Bm7-E7 to Bbm7-Eb7, Bm7 resolving to Bbm7).
  • Strategic deployment of bVII7#11 (Gb7#11) for unique backdoor dominant color or tritone substitution.
  • Brief minorization of the tonic (Abm7) followed by Ab6, creating subtle modal shifts within the Ab major key.

Improvisation Focus: Navigating complex chromaticism and precise arpeggio superimposition over rapid, non-diatonic harmonic shifts.

Difficulty Rating: 4 (Advanced Intermediate) - Demands precise ear training and technical proficiency to navigate frequent non-diatonic II-V progressions and Monk’s signature half-step root movements.
