Such was the liturgic chant in the ages of faith, before the invention of counterpoint and the first steps in modern musical science suggested new conceptions and methods in worship music. It constitutes to-day a unique and precious heritage from an era which, in its very ignorance, superstition, barbarism of manners, and ruthlessness of political ambition, furnishes strongest evidence of the divine origin of a faith which could triumph over such antagonisms. To the devout Catholic the chant has a sanctity which transcends even its aesthetic and historic value, but non-Catholic as well as Catholic may reverence it as a direct creation and a token of a mode of thought which, as at no epoch since, conceived prayer and praise as a Christian’s most urgent duty, and as an infallible means of gaining the favor of God. The Catholic liturgic chant, like all other monumental forms of art, has often suffered through the vicissitudes of taste which have beguiled even those whose official responsibilities would seem to constitute them the special custodians of this sacred treasure. Even to-day there are many clergymen and church musicians who have but a faint conception of the affluence of lovely melody and profound religious expression contained in this vast body of mediaeval music. Where purely aesthetic considerations have for a time prevailed, as they often will even in a Church in which tradition and symbolism exert so strong an influence as they do in the Catholic, this archaic form of melody has been neglected. Like all the older types (the sixteenth century _a capella_ chorus and the German rhythmic choral, for example) its austere speech has not been able to prevail against the fascinations of the modern brilliant and emotional style of church music which has emanated from instrumental art and the Italian aria. Under this latter influence, and the survival of the seventeenth-century contempt for everything mediaeval and “Gothic,” the chant was long looked upon with disdain as the offspring of a barbarous age, and only maintained at all out of unwilling deference to ecclesiastical authority. In the last few decades, however, probably as a detail of the reawakening in all departments of a study of the great works of older art, there has appeared a reaction in favor of a renewed culture of the Gregorian chant. The tendency toward sensationalism in church music has now begun to subside. The true ideal is seen to be in the past. Together with the new appreciation of Palestrina, Bach, and the older Anglican Church composers, the Catholic chant is coming to its rights, and an enlightened modern taste is beginning to realize the melodious beauty, the liturgic appropriateness, and the edifying power that lie in the ancient unison song. This movement is even now only in its inception; in the majority of church centres there is still apathy, and in consequence corruption of the old forms, crudity and coldness in execution.
