This is "the angelic voice spell"
Put an egg yolk into a glass. Add sugar and milk, then mix them very good untill it looks like a foam. Take the glass and put it near a candle. Light the candle and put a pentagram into the glass( wash it before). Then chant aloud: Gods and Goddesses, and angels from above, give me an angelic voice so that I can sing in your name forever more!''. Take out the pentagram( do not forget to wash it). Drink that egg yolk with milk and sugar slowly. After this blow out the candle. After two weeks of doing this daily, you will have an amazing voice.
(It is also good if you have a necklace) Good luck ^.^
