Harmonic Highlights

  • Employs a “Rhythm Changes” framework in C Major, characterized by persistent I-vi-ii-V (C-Am7-Dm7-G7) turnarounds.
  • The bridge (B section) uses a secondary dominant (C7) to tonicize the IV chord (F6), a hallmark of the 32-bar AABA form.
  • Features a cycle-of-fifths dominant chain (D7 to G7) to create harmonic momentum leading back to the final A section.

Improvisation Focus C Major Bebop scale and rhythmic displacement.

Difficulty Rating 4/5. While the underlying functional harmony is straightforward, the standard’s traditionally “breakneck” bebop tempo and angular melody require advanced technical facility and rhythmic precision.
