Yeah but its a sound isn't it?....the tritone bit....its a sound. Somebody somewhere at sometime felt that that combination which they heard and associate with some song or another was "vile and blasphemous and the work of the Devil!" How about a "backbeat?" I read an article in a friend's magazine (one that also explains the fallacies i evolution) that went into great depth about music with a "backbeat" being the "devil's music." Because it makes no sense to you or me doesn't mean it doesn't make sense to someone.
