Harmonic Highlights

  • Utilizes the “Rhythm Changes” framework, centered on rapid I-VI-ii-V turnarounds (Bbmaj7-G7-Cm7-F7) that define the A section.
  • Features a bridge sequence consisting of a dominant cycle of fifths (D7-G7-C7-F7), requiring smooth transitions between secondary dominants.
  • Employs a ii-V to the subdominant (Fm7-Bb7 to Ebmaj7) paired with an Ab7 backdoor dominant for added chromatic movement.

Improvisation Focus Bb Major Bebop Scale and Guide-Tone Linking.

Difficulty Rating 4/5. The high-velocity bebop tempo and harmonic density of two chords per bar require advanced technical fluency and rapid mental processing.
