Harmonic Highlights:

  • Classic 12-bar blues progression in Bb, built entirely on dominant 7th chords for I, IV, and V functions.
  • Prominent IV7 (Eb7) movement creates subdominant tension, frequently resolving back to the tonic I7 (Bb7).
  • The V7-I7 resolution (F7-Bb7) firmly establishes the turnaround, providing strong harmonic closure to the form.

Improvisation Focus: Bb Blues scale

Difficulty Rating: 2 (Beginner-Intermediate) – The underlying 12-bar blues form is foundational, though Monk’s melodic and rhythmic phrasing often presents an interpretative challenge.
