The simultaneous elaboration of myths relating to trees and birds as objects of worship, as beneficent or malign powers, and as the transmitters of oracles, necessarily confirmed and extended the personifications of speech and song, and were fused through many sources into a whole, which represented a supernatural agent, endowed with the power of a mediator, of a good or evil spirit or idol. This ultimately led to a universal conception of the efficacy of sound, considered as the manifestation of occult powers. In this mythically spiritual atmosphere, all peoples formerly lived and in great part still continue to live.
As the innate impulse led to the entification of speech and of the singing of men and animals, so it also led to the mythical personification of dancing and instrumental music, in which nearly all peoples have recognized a demoniac and deliberate power. For this reason, dancing and the noise of rude instruments generally accompanied solemn religious and civil ceremonies, and any remarkable cosmic, astral, or meteorological fact; and in polytheistic times the deities of poetry, dancing, and music served to accentuate and classify ideas.
The instrument became a fetish, and was invested with a mysterious power resembling that which was supposed to exist in all utterances of the animal world. Indeed, instruments were, and still are among savages, regarded as sacred and as an integral part of public worship, so that each had its definite function and office. This need not surprise us, since for such men every object is a fetish, which contains a soul. The Karens, a tribe in Burmah, believe that their arms, knives, utensils, etc., have all a kelap or soul, which is termed a wong by the negroes of West Africa. The same belief is found in a more explicit form among the Algonquins, the Fijians, and the aforesaid Karens, whose beliefs are characteristic of all peoples which have reached this stage of mythical conceptions. The different objects belonging to a dead man, and his instruments, arms, and utensils, are laid in his tomb, or burnt with his body, and this is owing to the belief that the souls of these objects follow their possessor into another life. The same custom unfortunately extends to persons, and there are instances of this evil practice among relatively civilized nations; the massacre which takes place at the death of a king of Dahomey is well known, and is revolting from the number of victims and from the mode of their sacrifice. It is therefore easy to imagine the way in which musical instruments and the sounds produced by them were personified, since these manifestations seemed to approximate more closely to those of animals.
