Turtles All the Way Down (soundtrack)

The film score is composed by Ian Hultquist.^[1] He began recording the score by December 2022 and completed within the same month. Ian considered the film to be really proud of as he liked John Green's novel, and the film being "gorgeous and sweet". Owing to tap into the emotional undertones, he borrowed some elements of the music which based on his personal life as well. The score utilizes strings, synths and guitars resulting in an indie pop quality.^[2][3] The final composition "Love is How You Become Real" was based on his own demo verbatim which Marks liked it eventually being used in the film.^{[2][4]: 40:38}

Season Kent served as the music supervisor, having worked on all of Green's film adaptations. Marks focused on utilizing upbeat pop numbers, to maintain the youthful rhythm and personally wrote fan letters to artists so that she could secure the licensing rights of those songs.^[5][6]

The soundtrack was released through WaterTower Music on May 3, 2024.^[7][8]

Lovia Gyarkye of The Hollywood Reporter wrote "Ian Hultquist's often brooding score feels most at home".^[9] Kate Bove of Screen Rant said that Hultquist's score ranges from "heartfelt to anxiety-inducing".^[10] Kate Erbland of IndieWire called it a "peppy" soundtrack.^[11]
