West Dylan Thordson’s soundtrack for Split does not sound like a traditional thriller album trying to shout its way through the room. It feels more unstable than that, which is exactly what the film needs. The score moves through dread, fragmentation, and sudden bursts of pressure, but it also keeps finding moments that feel strangely intimate, almost too close to the characters’ nerves.

That approach fits Split because the movie is built on identity breaking apart, re-forming, and refusing to stay contained, not suspense alone. Thordson’s music gives the film that unsteady pulse. The cues do not simply announce fear. They make the whole world feel off-balance, as if the room itself has started leaning in the wrong direction.

The soundtrack album was released in 2017 and gives the film’s atmosphere a life outside the movie. Fans who revisit it are not only returning to Kevin, Casey, or the final reveal that folds Split into a larger universe. They are returning to the texture of the movie itself, that cold, anxious rhythm that keeps everything feeling one step away from snapping.
