Harmonic Highlights

  • Employs a classic “Rhythm Changes” A-section (I - V7/ii - ii - V7 in Bb major) as its structural backbone, frequently cycling through these changes.
  • The bridge features temporary modulations, including a V-I to Eb (Bb7-Eb7 implied) and a series of descending dominant 7th chords (D7-G7) that resolve towards the tonic Bb.
  • Monk’s characteristic rhythmic displacements and strategic use of passing diminished chords (e.g., E07) provide harmonic interest and propel the progression.

Improvisation Focus Navigating ii-V-I and V7-I cycles through arpeggio superimposition and bebop scales.

Difficulty Rating 4 (Advanced Intermediate). The rapid harmonic rhythm and numerous secondary dominants demand strong melodic and harmonic agility.
