Seinfeld premiered on NBC in 1989 and ran until 1998, created by Jerry Seinfeld and Larry David. Composer Jonathan Wolff built its scene transitions around slap bass riffs, varying the licks to match the rhythm of Jerry's stand-up openings. Because almost every episode used them repeatedly, the sound became shorthand for the show itself. Clips later spread on soundboards and in edited videos, where the riff now marks any abrupt, awkward transition, even for viewers who have never watched a full episode of the classic sitcom.
