John Williams composed the film's score, which earned him an Academy Award and was later ranked the sixth-greatest score by the American Film Institute. The main "shark" theme, a simple alternating pattern of two notes variously identified as "E and F" or "F and F sharp" became a classic piece of suspense music, synonymous with approaching danger (see leading-tone). Williams described the theme as "grinding away at you, just as a shark would do, instinctual, relentless, unstoppable." The piece was performed by tuba player Tommy Johnson. When asked by Johnson why the melody was written in such a high register and not played by the more appropriate French horn, Williams responded that he wanted it to sound "a little more threatening". When Williams first demonstrated his idea to Spielberg, playing just the two notes on a piano, Spielberg was said to have laughed, thinking that it was a joke. As Williams saw similarities between Jaws and pirate movies, at other points in the score he evoked "pirate music", which he called "primal, but fun and entertaining". Calling for rapid, percussive string playing, the score contains echoes of La mer by Claude Debussy as well of Igor Stravinsky's The Rite of Spring.
There are various interpretations of the meaning and effectiveness of the primary music theme, which is widely described as one of the most recognizable cinematic themes of all time. Music scholar Joseph Cancellaro proposes that the two-note expression mimics the shark's heartbeat. According to Alexandre Tylski, like themes Bernard Herrmann wrote for Taxi Driver, North by Northwest, and particularly Mysterious Island, it suggests human respiration. He further argues that the score's strongest motif is actually "the split, the rupture"when it dramatically cuts off, as after Chrissie's death. The relationship between sound and silence is also taken advantage of in the way the audience is conditioned to associate the shark with its theme, which is exploited toward the film's climax when the shark suddenly appears with no musical introduction.
Spielberg later said that without Williams's score the film would have been only half as successful, and according to Williams it jumpstarted his career. He had previously scored Spielberg's debut feature, The Sugarland Express, and went on to collaborate with the director on almost all of his films. The original soundtrack for Jaws was released by MCA Records on LP in 1975, and as a CD in 1992, including roughly a half hour of music that Williams redid for the album. In 2000, two versions of the score were released: Decca/Universal reissued the soundtrack album to coincide with the release of the 25th-anniversary DVD, featuring the entire 51 minutes of the original score, and Varse Sarabande put out a rerecording of the score performed by the Royal Scottish National Orchestra, conducted by Joel McNeely.
