Seinfeld, the American sitcom that ran from 1989 to 1998, used short slap-bass stings to move between scenes instead of a traditional laugh-track transition. Those brief musical bridges became one of the show's most recognisable signatures, as familiar as its opening theme. As clips and edits spread online, creators began lifting the riff on its own to signal a scene change, an awkward pause or a Seinfeld-style punchline. Its brevity and instantly familiar groove keep it useful for short-form video, where a two-second cue can set the tone.
