This simple but haunting melody dates back centuries to a Gregorian Chant about the final judgment and has been used many times since, including by Rachmaninoff (Rhapsody on a Them of Paganini), Berlioz, Verdi (Requiem), Mozart and Wendy Carlos for the introductary music to The Shining. Even the grunge/sludge metal band Melvins has their own rendition. I recommend searching on Youtube for Carlos’ and Melvins’ versions.
