Ludwig Göransson composed the score for the film, after doing so for Nolan's previous film, Tenet. Göransson's score was featured in a trailer for the film on May 8, 2023. It was also featured in the Universal Pictures exclusive five-minute Opening Look on July 13. Nolan had advised him to use a solo violin for Oppenheimer's central theme in the film, with Göransson remarking that he had felt that it could go from "the most romantic, beautiful tone in a split second to neurotic and heart wrenching, horror sounds".
