Seinfeld ran on NBC from 1989 to 1998 and used music by composer Jonathan Wolff as its signature scene change sound. Wolff built the show's cues around sampled slap bass and mouth percussion that matched Jerry Seinfeld's stand-up rhythm, so each episode could cut quickly without traditional scoring. Clips of the riff later spread online as a shorthand for a sitcom transition, and editors still drop it into parodies, sketches and reaction videos whenever they want that unmistakable nineties comedy timing.
