No art is equal to music

“I firmly believe, nor am I ashamed to assert, that next to theology no art is equal to music; for it is the only one, except theology, which is able to give a quiet and happy mind. This is manifestly proved by the fact that the devil, the author of depressing care and distressing disturbances, almost flees from the sound of music as he does from the word of theology. This is the reason why the prophets practiced music more than any art and did not put their theology into geometry, into arithmetic, or into astronomy, but into music, intimately uniting theology and music, telling the truth in psalms and songs.”

– Martin Luther
