Music is hateful and intolerable to the devil. I truly believe, and do not mind saying, that there is no art like music, next to theology. It is the only art, next to theology, that can calm the agitations of the soul, which plainly shows that the devil, the source of anxiety and sadness, flees from the sound of music as he does from religious worship. That is why the scriptures are full of psalms and hymns, in which praise is given to God. That is why, when we gather round God’s throne in heaven, we shall sing his glory. Music is the perfect way to express our love and devotion to God. It is one of the most magnificent and delightful presents God has given us.
– Martin Luther
