The musical score for Evergrace was composed by Kota Hoshino. He stated in an interview that voices are used as the primary "instrument" in the game's soundtrack. Hoshino recorded samples of his own voice and edited them with Soundforge, then recorded more voice samples to create what he considers to be an ethnic sound. Japanese instruments such as the shakuhachi and the shamisen were also added. All the score's percussion was synthesized.
