ABSTRACT
Like painting, sculpture, architecture, and literature, music, so far as these forms are concerned, has different dominant styles in various cultures at the same moment, and at various stages of the same culture in the course of time. In one culture or in one period the Ideational form may be dominant; in another culture or period the Sensate music may be the main form. Side by side with these conspicuous differences, the purity or intensity of each style may also fluctuate. That the grand music of the fifth to the twelfth centuries was almost monopolistically Ideational is testified to by the fact that the main and almost its only form was the plain chant and then the religious hymns and psalmodies. Then on the highway of grand music for the first time appears secular music, more worldly, more embellished and less Ideational than the chants.
