Another explanation of the ancient view of music as possessing a controlling power over emotion, thought, and conduct lies in the fact that music existed only in its rude primal elements; antiquity in its conception and use of music never passed far beyond that point where tone was the outcome of simple emotional states, and to which notions of precise intellectual significance still clung. Whatever theory of the origin of music may finally prevail, there can be no question that music in its primitive condition is more directly the outcome of clearly realized feeling than it is when developed into a free, intellectualized, and heterogeneous art form. Music, the more it rises into an art, the more it exerts a purely aesthetic effect through its action upon intelligences that delight in form, organization, and ideal motion, loses in equal proportion the emotional definiteness that exists in simple and spontaneous tone inflections. The earliest reasoning on the rationale of musical effects always takes for granted that music’s purpose is to convey exact ideas, or at least express definite emotion. Music did not advance so far among the ancients that they were able to escape from this naturalistic conception. They could conceive of no higher purpose in music than to move the mind in definite directions, and so they maintained that it always did so. Even in modern life numberless instances prove that the music which exerts the greatest effect over the impulses is not the mature and complex art of the masters, but the simple strains which emanate from the people and bring up recollections which in themselves alone have power to stir the heart. The song that melts a congregation to tears, the patriotic air that fires the enthusiasm of an assembly on the eve of a political crisis, the strain that nerves an army to desperate endeavor, is not an elaborate work of art, but a simple and obvious tune, which finds its real force in association. All this is especially true of music employed for religious ends, and we find in such facts a reason why it could make no progress in ancient times, certainly none where it was under the control of an organized social caste. For the priestly order is always conservative, and in antiquity this conservatism petrified melody, at the same time with the rites to which it adhered, into stereotyped formulas. Where music is bound up with a ritual, innovation in the one is discountenanced as tending to loosen the traditional strictness of the other.
