Seinfeld premiered on NBC in 1989 and ran until 1998, with composer Jonathan Wolff creating a distinctive musical language built around a synthesized slap bass, finger snaps and vocal mouth sounds. Each episode used slightly different riffs to bridge stand up segments and scenes, which made the transitions as recognisable as the characters themselves. Clips and edits online later isolated those brief interludes, and creators began dropping them into unrelated footage to instantly frame a moment as sitcom awkwardness, a use that keeps the riff familiar far beyond reruns.
