Harmonic Highlights

  • The structure blends a 12-bar blues in C major with an 8-bar bridge, creating an expanded AABA form that demands both blues and bebop vocabulary.
  • The bridge initiates with a bVImaj7 to V7 (Abmaj7 to G7#9) motion, providing a sophisticated chromatic approach to the primary dominant.
  • Rapid-fire sequential ii-V progressions (Em7-A7 to Dm7-G7) characterize the bridge, requiring smooth voice leading across the cycle of fourths.

Improvisation Focus Integrating the C Blues scale for the A sections with precise Altered and Mixolydian scales to navigate the bridge’s dense harmonic movement.

Difficulty Rating 3/5: While the A sections are accessible blues, the bridge requires technical proficiency to navigate fast-moving ii-V cycles and chromatic transitions.
