Most modern dances, silently performed in couples, are merely lively movements; but in all ancient performances of the sort the idea is as essential as the form. Precisely as the meaningless refrains of many ballads arise from a forgetfulness of intelligible words, dances which are only motion grew out of dances which expressed something. The dance was originally the dramatized expression of any feature of nature or life which excited interest. Every department of human labor--the work of the farmer, weaver, or tradesman; the church, the court, and the army; the habits and movements of the animals which seem so near to man in his simplicity, and in whose life he takes so active an interest; the ways and works of the potent supernatural beings, good or evil, or, rather, beneficent or dangerous, by whom he believes himself surrounded; angel and devil, witch and ogre--representations of all these served, each in turn, for the amusement of an idle hour, when the labor which is the bitterness of the enforced workman is a jest to the free youth, and the introduction of spiritual fears which constitute the terror of darkness only adds an agreeable excitement to the sports of the play-ground. All this was expressed in song shared by the whole company, which was once the invariable attendant of the dance, so that the two made up but one idea, and to "sing a dance" and "dance a song" were identical expressions. The children's rounds of to-day, in which each form of words has its accompanying arrangement of the ring, its significant motion and gesture, thus possess historic interest. For these preserve for us some picture of the conduct of the ballads, dances, and games which were once the amusement of the palace as of the hamlet. The form of the verses used in the games also deserves note. These usually consist either of a rhyming couplet, or of four lines in which the second and fourth rhyme; they are often accompanied by a refrain, which may be a single added line, or may be made up of two lines inserted into the stanza; and in place of exact consonance, any assonance, or similarity of sound, will answer for the rhyme. Above all, they possess the freedom and quaintness, the tendency to vary in detail while preserving the general idea, which distinguish a living oral tradition from the monotonous printed page; in these respects, our rhymes, humble though they be, are marked as the last echo of the ancient popular poetry.
