LESTER LEAPS IN - Free Jazz Leadsheet

Composed by Lester Young in 1939, "Lester Leaps In" is a landmark swing-era jazz standard. Its riff-based melody and blues-inflected harmony encourage energetic improvisation.

Recorded by Count Basie and other swing bands, performances highlight solo exchanges, rhythmic drive, and interplay between ensemble sections.

The tune remains a cornerstone of swing and jam session repertoire.
