Seinfeld was a hugely popular American sitcom that ran on NBC from 1989 to 1998, starring Jerry Seinfeld as a fictional version of himself navigating everyday life in New York. The show used short bursts of slap bass music to bridge scenes, and those few notes became one of its most recognisable signatures. Like the Law and Order DUN DUN sting, it works without any context. Clips, edits and memes reused the riff online, turning it into shorthand for a scene change or an awkward pause, and creators still reach for it because audiences recognise the joke instantly.
