John Williams composed the Jaws theme for Steven Spielberg's 1975 film Jaws, where the simple two-note motif signalled the unseen shark and became one of the most recognisable pieces of film music ever written. The cue was parodied and quoted in countless films, television shows and adverts long before short-form video, and creators later trimmed it into a few seconds for memes and edits. Its power lies in that shared cultural memory: almost everyone knows what is coming when those notes start, even if they have never seen the film.
