Recently I played one of my piano compositions and after playing for about a minute I heard some door knock/banging noises. I checked the door and no one was there. I resumed playing the piano/synthesizer and again heard banging before finishing. I also felt like I might be attracting demons because the music I have composed is a bit odd, like if a person experiencing psychosis were to compose music. I do consider the music to be in the same category as "The Raven" by Poe, which I know, it's a poem, but imagine that poem in musical form and you get the idea. So, having had firsthand experience with demons prior to this I have decided to stop playing musical instruments for the time being. I don't even trust myself to be able to compose uplifting music. Instead, it's like the music I compose is a form of bashing people over the head. I guess the demons like that, which is why I'm stopping. Anyway, the reason I'm including this background info is for the sake of warning. Once it becomes apparent to a person that he or she can attract demons, then everything a person does needs to be done carefully so as not to invite demonic attack. Perhaps I am saying too much. My question is: what are some Orthodox piano pieces that are good for creating a holy atmosphere, if there are any? I'm under the impression that Divine Liturgy music is only vocal, but does this mean that it is impossible to compose a holy piano piece? I'm afraid to even attempt to play Moonlight Sonata, even though I don't normally think of it as "occult." Is it true that any action a person takes is either good or bad?
