The music comes from Jaws, Steven Spielberg’s 1975 thriller about a great white shark terrorizing a seaside community. Composer John Williams built its signature suspense around a simple alternating two-note motif, performed with increasing speed and intensity. The score won the Academy Award for Best Original Dramatic Score and became one of cinema’s most recognizable musical warnings. Decades of parodies, television references, memes, and short video edits have kept the theme closely associated with sharks, pursuit, and approaching danger.
