Our experience of the world often involves hearing our environment before seeing it. Whether it’s the sound of something moving through nearby water, or the rustling of vegetation, our fear of the unseen is rooted in our survival instincts as a species.

Cinematic sound and music taps into these somewhat unsettling instincts – and this is exactly what director Steven Spielberg and composer John Williams achieved in the iconic 1975 thriller Jaws.
