"It Follows" (2014), written and directed by David Robert Mitchell, premiered at the Cannes Film Festival in 2014. It chronicles the story of Jay, a college student who contracts a curse through sexual intercourse. The curse manifests itself as a human whom only the infected persons can see, always following at a walking pace, and determined to kill if it catches up. This thesis demonstrates the score's crucial role in establishing affect, setting, and character in a film with sparse dialogue and a silent monster. Moreover, the score creates a sense of the uncanny by complicating the binary between music and sound effect and fulfills the need to create dread without resorting to the loud or sudden sounds traditionally heard in horror films. The score's composer, Richard Vreeland, achieves this effect by drawing on both classical film scoring techniques as well as more modern horror scoring styles. It is this interaction between styles that enhances the viewers' experience of dread and horror in the film. This thesis analyzes how Vreeland's score for "It Follows" exploits the poetics of the fantastical gap, of the uncanny, and of musical semiosis. I primarily focus on the "Heels" theme and use of drones in "It Follows," tracing how these musical features blur the distinction between what is score and what is sound effect. I also examine the use of melodic themes in a primarily non-melodic score. By analyzing these elements, I show how Richard Vreeland uses both classical and modern scoring techniques to answer his own question: "Why is this scary? What could push that emotion even further?"
