Music and noise are similar in many ways, but also different in some important ways. While noise is disturbing and often a nuisance, music is relaxing, exciting, and has positive affects on human emotion. Human feelings toward music or noise can be an unconscious state of the mind or it may be a learned reaction and perception. For example if we play  music for a person who has never heard music in his life, he may or may not show any reaction to that music. Also we don't know what is the reaction of animals, specially monkeys and other primates to music.
