Seinfeld premiered on NBC in 1989 and ran until 1998, created by Jerry Seinfeld and Larry David. Composer Jonathan Wolff gave the show its distinctive musical identity, using slap style bass lines and mouth made percussive sounds to bridge stand up segments and scenes. Because episodes rarely used traditional score cues, those short bass breaks became one of television's most recognisable transitions. Clips later circulated on soundboards and in video edits, where the riff alone now tells viewers a comedic scene change is coming, even without any footage from the series itself.
