I was searching for a demon ritual on google, and I came across this: http://www.biblerevelations.org/articles/demon_possession_music.htm Spirit Possession and Music Having established that spirit possession does take place, the possibility of the role of music in possession may be examined. Satan has always been highly involved with music, beginning in heaven. "Satan had led the heavenly choir." The Story of Redemption, 25. This suggests that Satan is the most intelligent being regarding music in our world. He knows how to make the best use of it to achieve his ends. He does things with music that seem strange and even impossible. The search for the use of music in devil possession resulted in finding two main avenues. One is the use of beats in music to call the spirits or gods. The other is the altered state of consciousness. Cool eh?
