To speak now of the effect of music on animals. It is best to make experiments with those animals that are much associated with man, such as the horse, the dog, the cows and oxen, and pet animals, such as parrots and cockatoos. By association with man, these animals have some human qualities reflected onto them. The horse that is associated with man has much more kindness, much more sympathy and understanding, than the horse in the jungle. The dog that lives with man becomes faithful, obedient. The wild dog is a very fierce animal.
