The signature Seinfeld scene-transition music was composed by Jonathan Wolff for the NBC sitcom, which ran from 1989 to 1998, and performed on electric bass in a slap-funk style rather than a traditional theme song. Each episode used dozens of short improvised-sounding stings to cover cuts between scenes. The riff became one of television's most parodied sounds, quoted in comedy sketches and YouTube edits alongside other iconic TV transition stings, and it survives as meme shorthand for an awkward or ironic everyday moment.
