Harmonic Highlights

  • Features Monk’s signature chromatically descending dominant progression (Ab7-Gb7) before resolving to Cm7.
  • Includes a clear, albeit brief, modulation to Eb major (Fm7-Bb7b9-Ebmaj7), the relative major’s parallel major.
  • Employs persistent iim7-V7 cycles (Cm7-F7) that often lead to unexpected key areas or serve as extended turnarounds.
  • The C7-F7 progression introduces a secondary dominant (V7/F) or bIIIdom7 in Cm, adding harmonic tension before resolving.

Improvisation Focus Navigating the numerous dominant seven chords and their often unconventional resolutions.

Difficulty Rating 4 (Advanced). The rapid, unpredictable modulations and chromatic dominant movements demand a sophisticated harmonic vocabulary.
