Seinfeld, the American sitcom created by Jerry Seinfeld and Larry David, ran on NBC from 1989 to 1998, with music by Jonathan Wolff built around a distinctive slap bass theme. Short bass riffs like this one were used between scenes to bridge jokes and locations, and they became inseparable from the show's rhythm. Clips of the transitions spread through YouTube compilations, memes and soundboards, where editors reuse them to give ordinary videos a sitcom feel. Like the Law and Order sting, the riff works because viewers recognise it instantly, even from a few notes.
