We all know the sound. It’s that quirky slapped bass that opens while Jerry Seinfeld does his comedic monologue, and then hilarity ensues. The little ditty was written by Jonathan Wolf. When hired for the job he listened to Jerry’s stand-up and found a sort of melody and rhythm to his delivery. Knowing that he couldn’t actually write a melodic theme over the monologue, he sort of timed it instead. The tempo, about 110, became the basis for a simple slapped bass line. With Jerry in studio, he recorded the line while Jerry did his thing. And that has become the popular and recognizable Seinfeld theme.
