Seinfeld premiered on NBC in 1989 and ran until 1998, starring Jerry Seinfeld as a fictionalised version of himself in New York. Composer Jonathan Wolff created its distinctive music using a synthesised slap bass, building a different riff to bridge scenes instead of a traditional theme song. Those short transitions became one of the show's signatures, widely imitated and parodied in other sitcoms. Online, the riff survived the series through memes and edits, where a single hit instantly frames everyday moments as sitcom scenes.
