A C major bebop piece at 145 BPM — the fastest in the collection. Bebop is jazz with the tempo accelerated past the point where you can follow individual notes: you perceive the shape of the phrase rather than each pitch. The organ melody runs up the C major scale (C5–D5–E5–F5–G5) in the opening bar, peaks on A5 in bar 5, then cascades down. I-vi-ii-V (Cmaj7–Am7–Dm7–G7) is the foundational cycle-of-fourths that drives bebop harmony: each chord is a fifth below the last, creating relentless forward motion. G7 → Cmaj7 is the 'turnaround' that snaps back to the beginning of the loop.
