Michael Giacchino composed the film's score; this was his fifth collaboration with Pixar and his second collaboration with Pete Docter after Up. The producers first met with Giacchino to explain the film's concept and screen it for him. In response, he composed an eight-minute suite of music, unconnected to the film, based on his emotions viewing it.[28] Rivera noted that while both Giacchino and Docter were musicians, they discussed the film in terms of story and character.[28]
