  • Prevalence of highly altered dominant chords (e.g., C7b5b9, F7#9#11, G7#11, F13#11) creates dense harmonic tension.
  • Deceptive resolutions are central, exemplified by Db7 (V of Gb) resolving unexpectedly to Fm7, a Monk signature.
  • Rapid and abrupt temporary modulations, such as the ii-V-I in Ab major (Bbm7-Eb7#11-Abmaj7), frequently challenge the tonal center.

Improvisation Focus: Altered Scale (Superlocrian) for the numerous dominant chords.

Difficulty Rating: 5 (Advanced). Extremely unpredictable harmonic movement, frequent altered dominants, and deceptive resolutions demand deep theoretical understanding and ear training.
