Seinfeld premiered on NBC in 1989 and ran until 1998, starring Jerry Seinfeld as a fictionalized version of himself in New York. Composer Jonathan Wolff created its distinctive musical identity around slap bass phrases that were tailored to Seinfeld's stand-up segments and scene changes. Unlike a traditional sitcom theme, these short riffs became part of the editing language of the show. Through decades of reruns, clips, and online edits, the bass cue has outlived the series as a universal shorthand for a witty transition or a comedic beat.
