As with every "Dragon Quest", Koichi Sugiyama composed the music and directed all the associated spinoffs. The song heard during gameplay depends on a number of factors. A specific track is always played for towns, another for caves or dungeons, another while the party is mounted on the hot air balloon, for instance. Lastly, while out in the world, each of the first four acts has its own theme song, as does the Hero—in act five, the theme song played depends on who is the first character in the formation.
