Chant is speech-song, probably the earliest form of vocal music; it proceeds from the modulations of impassioned speech; it results from the need of regulating and perpetuating these modulations when certain exigencies require a common and impressive form of utterance, as in religious rites, public rejoicing or mourning, etc. The necessity of filling large spaces almost inevitably involves the use of balanced cadences. Poetic recitation among ancient and primitive peoples is never recited in the ordinary level pitch of voice in speech, but always in musical inflections, controlled by some principle of order. Under the authority of a permanent corporate institution these inflections are reduced to a system, and are imposed upon all whose office it is to administer the public ceremonies of worship. This is the origin of the liturgic chant of ancient peoples, and also, by historic continuation, of the Gregorian melody. The Catholic chant is a projection into modern art of the altar song of Greece, Judaea, and Egypt, and through these nations reaches back to that epoch of unknown remoteness when mankind first began to conceive of invisible powers to be invoked or appeased. A large measure of the impressiveness of the liturgic chant, therefore, is due to its historic religious associations. It forms a connecting link between ancient religion and the Christian, and perpetuates to our own day an ideal of sacred music which is as old as religious music itself. It is a striking fact that only within the last six hundred or seven hundred years, and only within the bounds of Christendom, has an artificial form of worship music arisen in which musical forms have become emancipated from subjection to the rhetorical laws of speech, and been built up under the shaping force of inherent musical laws, gaining a more or less free play for the creative impulses of an independent art. The conception which is realized in the Gregorian chant, and which exclusively prevailed until the rise of the modern polyphonic system, is that of music in subjection to rite and liturgy, its own charms merged and, so far as conscious intention goes, lost in the paramount significance of text and action. It is for this reason, together with the historic relation of chant and liturgy, that the rulers of the Catholic Church have always labored so strenuously for uniformity in the liturgic chant as well as for its perpetuity. There are even churchmen at the present time who urge the abandonment of all the modern forms of harmonized music and the restoration of the unison chant to every detail of the service. A notion so ascetic and monastic can never prevail, but one who has fully entered into the spirit of the Plain Song melodies can at least sympathize with the reverence which such a reactionary attitude implies. There is a solemn unearthly sweetness in these tones which appeals irresistibly to those who have become habituated to them. They have maintained for
