Seinfeld, the American sitcom that ran on NBC from 1989 to 1998, used short slap bass interludes composed by Jonathan Wolff to move between scenes instead of a traditional laugh track transition. Those brief riffs became one of the show's most recognisable signatures, and clips of them spread widely as memes and editing sounds on YouTube, TikTok and in video essays. Creators still reach for the riff because it instantly reads as classic sitcom comedy, even for viewers who never watched the original series.
