ONE O'CLOCK JUMP - Free Jazz Leadsheet

Composed by Count Basie in 1937, “One O’Clock Jump” became a signature piece of his orchestra and a swing era classic.

The tune is a 12-bar blues with a strong riff-based structure, allowing soloists to improvise extensively. Famous recordings include Basie’s original and subsequent interpretations by jazz big bands and small combos.

Its driving rhythm and energetic riffs exemplify Kansas City swing style, making it a staple in jazz repertoire.
