Dune: Original Soundtrack Recording (1984)

The most memorable motif is almost identical to part of Ronald Stein's The Haunted Palace (1963) score, but it works in both settings, so I'm able to forgive the 'coincidence'.
The individual Houses are well-represented through varied use of percussion and there's even a romantic theme or two, should you feel the need for a dreamy accompaniment to the overwhelming heroism. Track titles are super-spoilery, so if you've not seen the film that it was written for or read the Frank Herbert book the film was based upon, then approach the music with caution.
