Composed by Jonathan Wolff, the Seinfeld theme debuted with the NBC sitcom in 1989 and ran through the show's finale in 1998, replacing a conventional theme song with a quirky slap-bass groove that played over scene transitions. The riff outlived the show as an internet shorthand for comedy, soundtracking countless YouTube edits, TikTok skits and meme compilations in the 2010s. Its longevity comes from instant recognition: a few popping notes tell viewers a joke is landing, no setup required.
