A man of true genius in any of the imitative arts, and there is not one that has a juster claim to that title than the art of dancing, sensible that nature is the varied and abundant spring of all objects of imitation, considers her and all her effects with a far different eye from those who have no intention of availing themselves of the matter she furnishes for observation. He will discover essential differences between objects, where a superficial beholder sees nothing but sameness; and in his imitation he will so well know how to render those differences discernible, that in the composition of his dance, the most trite subject will assume the air of novelty with the grace of variety. There is nothing disgusts so much as repetitions of the same thing; and a composer of dances will avoid them as studiously as painters do in their pieces, or writers tautology. The public complains, with great reason, that dances are frequently void of action, which is the fault of the performers not giving themselves the trouble to study just ones: satisfied with the more mechanical part of dancing, they never think of connecting the part of the actor with it, which however is indispensably necessary to give to their performance, spirit, and animation. A dance without meaning is a very insipid botch. The subject of the composition should always be strictly connected to the dances, so as that they should be in equal correspondence to one another. And, where a dance is expletively introduced in the intervals of the acts, the subject of it should have, at least, some affinity to the piece. A long custom has made the want of this attention pass unnoticed. It is surely an absurd and an unnatural patchwork, between the acts of a deep tragedy, to bring on, abruptly by way of diversion, a comic dance. By this contrast both entertainments are hurt; the abruptness of the transition is intolerable to the audience; and the thread, especially of the tragic fable, is unpleasingly broken. The spectators cannot bear to be so suddenly tossed from the serious to the mirthful, and from the mirthful to the serious. In short, such an heterogeneous adulteration has all the absurdity reproached to the motley mixture in tragi-comedy, without any thing of that connection which is preserved in that kind of justly exploded dramatic composition. How easy too to avoid this defect, by adapting the subjects of the dances to the different exigences of the different dramas, whether serious, comic, or farcical!
