Dumbo

On October 4, 2017, Danny Elfman was revealed to be composing the film's score. Elfman said that "[he and the production team] knew [they] would have to find a musical identity for Dumbo that was purely Dumbo". Elfman developed the film's main theme as "a very simple theme" as Burton "feels it's a simple story". Elfman also wrote background music for the film's scenes in the circus, as well as themes based on the characters' experiences. He also wrote a theme for Medici and Vandevere which he described as "a bit of a wicked thing". The score plays homage to Frank Churchill and Oliver Wallace's score from the original film.

Norwegian singer Aurora performed a cover of the original film's song "Baby Mine" for the remake's trailer, though it won't be featured in the actual film. Sharon Rooney will perform the song in the film. Additionally, Arcade Fire will perform an end-credits version of "Baby Mine" for the film, which was released as a single in March 11, 2019. Instrumental versions of the songs "Casey Junior", "When I See an Elephant Fly", and "Pink Elephants on Parade" from the original version are also featured in the film. The soundtrack, featuring Elfman's score and Arcade Fire's version of "Baby Mine", will be digitally released on March 29, 2019, and will be physically released on April 5, 2019.
