Heretic music

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 Heretic soundtrack was meant to sound "dark, angry, and dissonant", making use of the, diminished chords, and whatever other musical methods "sounded right" to evoke this mood.

The tracks in Heretic are only labeled in the IWAD with the headers of the levels for which they were originally written. Track names, and a few comments, were provided by Schilder after being queried about it, the relevant documents are available here.
