Vinyl LP pressing. Original soundtrack to the 1975 motion picture. 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 became a classic piece of suspense music, synonymous with approaching danger. 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".
