In collecting and studying the music of primitive peoples great difficulty is experienced in obtaining trustworthy data. Almost all the savage and semi-barbarous peoples of the world at the present day have been in contact more or less with civilized man for so long that they have acquired by imitation many of his manners, customs, and ideas. Thus the savage’s original development has been overlaid as it were with a varnish of culture, which is foreign, not native, to him. The first civilized men to come in contact with a savage tribe have not as a rule been intent upon observing their manners and customs nor upon recording their primitive music or folk-lore. These first men have usually come as discoverers and as conquerors. They have been followed by missionaries, who in their zeal to perpetuate the doctrines of Christianity have been ever anxious to divert the minds of the people from their ancient traditions, by substituting for them stories from Bible history. Their ancient songs and barbarous-sounding incantations, however interesting to the ethnologist, have been in most cases tabooed by the missionaries as impious, who substituted for them the hymns of the church. This thing has happened in Australia, New Zealand, Polynesia, Africa, and particularly in America, the Indian tribes having been so inoculated with musical ideas, hymns, and scraps of folk song, that it is frequently only with great difficulty that the character of their own primitive music can be determined. A collection of the music of the Hopi tribe, who dwell in seven naturally fortified hill towns in the desert of Arizona, reveals to a large extent Spanish influence. Many of their melodies have the grace and movement of Spanish dances. This is quite explicable, however, when it is remembered that the Spanish held dominion over these towns from 1580 to 1680. Spanish influence is also apparent in the music of the aboriginal inhabitants of the Philippine Islands, and in the traditional music of the Mexicans and Peruvians. Brasseur de Bourbourg has translated into French from the Quinche, the former Mayan tongue, an ancient manuscript called 'Rabinal-Achi.’ It is an immense dramatic ballet accompanied by music and danced and acted by hundreds of performers. But when we come to examine this music it is only to find that it has an unmistakably Spanish character.
