Uematsu composed nine tracks from Chrono Trigger's soundtrack, although one of those was only a jingles. The songs "Sealed Door", "People Who Threw Away the Will to Live", "Tyran Castle", "Silent Light", "Underground Sewer", "Burn! Bobonga!" "Bike Chase", and "Primitive Mountain" are his work, as is the jingle "Mystery of the Past".

Noriko Matsueda also co-composed one track from the game, "Boss Battle 1", for which Uematsu provided the arrangement.
