Seinfeld premiered on NBC in 1989 and ran until 1998, created by Jerry Seinfeld and Larry David. Composer Jonathan Wolff wrote its distinctive transition music, varying the slap bass riff to match each episode and scene change. Unlike a traditional sitcom theme with lyrics, the bassline became the show's signature sound. Decades later, clips and edits online revived it as shorthand for a sitcom cut, with creators using the riff whenever a moment needs an instant, recognisable change of scene or tone.
