The Heretic soundtrack was created by Kevin Schilder of Raven Software. As should be expected from the fantasy setting of the game, in contrast to Doom's science fiction theme, the music is composed in a completely different style. Heretic's soundtrack is more ambient and has diverse instrumentation, with significant use of percussion, harps, and choral voices. Many tracks are highly rhythmic and evoke an exotic, fantasy action atmosphere similar to typical motion picture soundtracks in the same genre.
The tracks in Heretic are unnamed according to Kevin Schilder, and were only labeled in the IWAD with the headers of the levels for which they were originally written.
