The slap-bass transition stings were created for Seinfeld, the NBC sitcom that ran from 1989 to 1998, with composer Jonathan Wolff building short bass interludes to bridge scenes instead of a traditional theme. Each sting was improvised around the episode timing, giving the show its loose, funky signature. Online, the riff escaped the show and became shorthand for an awkward punchline or ironic cut, sampled across YouTube sketches, TikTok edits and meme compilations, where a few twangy notes instantly signal classic nineties sitcom comedy.
