- Employs the “Rhythm Changes” structure in Bb Major, characterized by rapid I-VI-ii-V (Bbmaj7-G7-Cm7-F7) turnarounds.
- The bridge follows a sequential circle of fifths using dominant seventh chords (D7-G7-C7-F7) to create chromatic tension before returning to the tonic.
- Includes a secondary ii-V progression (Fm7-Bb7) to tonicize the IV chord (Eb7), introducing brief subdominant minor coloring.
- Utilizes constant harmonic motion where chords change every two beats, requiring vertical alignment within a horizontal melodic flow.
Improvisation Focus Continuous eighth-note linear phrasing using the Bb dominant bebop scale to navigate high-speed ii-V-I cells.
Difficulty Rating 4/5. The relentless tempo and necessity for precise harmonic synchronization during rapid-fire chord changes require advanced technical facility and melodic ear training.
