- The progression functions as a contrafact of “All God’s Chillun Got Rhythm,” utilizing a high-velocity structure in F Major despite the prompt’s C major label.
- Features rapid-fire secondary II-V cycles (Am7–D7b9 and Bm7–E7b9) that momentarily shift the tonal center through chromatic subdominant relationships.
- Employs a standard bebop turnaround (Gm7–C7) to resolve back to the tonic Fmaj7, maintaining constant forward motion.
- Frequent use of dominant 7th chords with flat-9 tensions (D7b9, E7b9) provides the signature dissonant “crunch” required for authentic bebop lines.
Improvisation Focus Continuous voice-leading through the 3rds and 7ths of rapid II-V-I chains.
Difficulty Rating 4/5; the fast harmonic rhythm and chromatic shifts between non-diatonic keys demand high-level technical facility and harmonic foresight.
