How The Exorcist Changed the Sound of Horror

Why do so many horror film scores today sound similar to The Exorcist from 1973? A lot of that is thanks to Krzysztof Penderecki, a Polish composer whose music was used by director William Friedkin to score The Exorcist. Penderecki's music can be heard in the works of Stanley Kubrick and David Lynch, and has even inspired the scores of modern horror films such as Bird Box.
