Seinfeld, the American sitcom starring Jerry Seinfeld that ran on NBC from 1989 to 1998, used short slap bass interludes to move between scenes instead of a traditional laugh track transition. The show's composer Jonathan Wolff created the percussive bass sound that became its signature, and the brief riffs soon became shorthand for the series itself. As clips, edits and parodies spread online, creators began lifting the transition to signal a Seinfeld-style cut, and its instantly recognisable groove keeps it useful for comedy timing today.
