Prelude, Fugue and Riffs is a "written-out" jazz-in-concert-hall composition composed by Leonard Bernstein for a jazz ensemble featuring solo clarinet.

Instead, it received its premiere on Bernstein's Omnibus television show, The World of Jazz on October 16, 1955.

[1][2] The soloist for the work's TV premiere was Al Gallodoro;[2] he is seen in the preserved 1955 video playing alto saxophone and then the clarinet solo passages.

[1] In 1952 Bernstein revised the score from its original instrumentation for a more conventional pit orchestra, and the work was then incorporated into a ballet sequence in the first draft of the musical comedy Wonderful Town.

The revised version of Prelude, Fugue and Riffs did not survive and the majority of the music was cut from the final version of the Wonderful Town score with the exception of a few phrases in the musical's numbers "Conquering the City" and "Conversation Piece".
