The score, composed by Laura Karpman, was released by Hollywood Records on November 8, 2023, in the United States.

In January 2022, Laura Karpman was hired to compose the score for the film, after previously doing so for the first season of the MCU television series What If...?

"[3] In late-2022, Karpman recorded a "space opera", as per DaCosta's request, seeking Basso profundo, bass singers, and male countertenors having them "sing in their falsettos, which meant they were singing in their head voice to give an odd sound".

For Khan's theme, Karpman resolved to bring in some "fantastic" musicians from Pakistan and India to collaborate with her to make an important theme that could represent Khan's heritage most of the time, creating incredible sounds that "augment, blend and explode" a traditional Marvel superhero, opining that a character like Khan shouldn't be othered and that her "big grown superhero" theme is about her adolescence, considering how her background was important in her show.

[3] All music is composed by Laura Karpman.Zanobard Reviews assigned an 8/10 to the album, summarising that "Laura Karpman's The Marvels is a superhero score done right, weaving a stunningly-crafted new main theme with thunderous orchestra and exquisite vocals through eighty minutes of spectactular musical story-telling.

It is a shame that Pinar Toprak's Captain Marvel theme doesn't return though.

"[10] Music critic Jonathan Broxton said "The Marvels is a triumph of a superhero score, one of the best of its type this year, and should put the final nail in the coffin of the notion that women composers can't write large-scale, exciting, super-hero action music – Karpman blows that tired opinion completely into space.

"[11] A review from Filmtracks stated that "Karpman succeeds in providing a highly intelligent and accomplished score filled with sonic intrigue, but not necessarily one at comfort with the concept or the general sound of the other scores in the Marvel Cinematic Universe.
