The soundtrack was composed by Jeremy Soule. While in Highschool, he played a lot of games and felt that soundtracks "lacked drama and intensity." He composed a demo to showcase what he believed music should sound like in games, and showed it to Square. They hired him as an in-house composer, and set him to work on Secret of Evermore as his first game.

The soundtrack was released on CD with 29 tracks, 8 of which were arranged versions of the in-game soundtrack. It was released as a pre-order bonus for the game.
