One great source of this disorder, is probably the managers considering dances in nothing better than in the light of merely a mechanical execution for the amusement of the eye, and incapable of speaking to the mind. And in this mistake they are certainly justifiable by the great degeneracy of this art, from the pitch of perfection to which it was antiently carried, and to which the encouragement of the public could not fail to restore it. The managers would then see their interest too clearly in consulting the greater pleasure of the public, not to afford to this art, the requisite cultivation and means of improvement.
The composer, who must even have something of the poet in him; the musician, the painter, the mechanic, are essentially necessary to the contribution of their respective arts, towards the harmony and perfection of composition, in a fine dramatic dance; even the dresses are no inconsiderable part of the entertainment. The _costume_, or in a more general term, propriety, should have the direction of them. It is not magnificence, that is the great point, but their being well assorted to character and circumstances. The French are notoriously faulty in over-dressing their characters, and in making them fine and showy, where their simplicity would be their greatest ornament. I do not mean a simplicity that should have any thing mean, low or indifferent in it; but, for example, in rural characters, the simplicity of nature, if I may use the expression, in her holy-day-cloaths.
As to the decorations and machines especially, I know of no place where there is less excuse for their being deficient in them than in London, where they are too manifestly, to bear any suspicion of flattery in the attributing it to them, executed to a perfection that is not known in any other part of Europe. The quickness with which the shifts and deceptions in the pantomime entertainments are performed here, have been attempted in many other parts; but the persons there employed, not having the same skill and depth in mechanics as the artists here, cannot come up to them in this point. And it is in this point precisely that a composer of dances may be furnished with great assistence in the effects from the theatrical illusion. And in an entertainment, where by an established tacit agreement between the audience and performers, there is such a latitude of introducing superhuman personages, either of the heathen deities, or of fairy-hood, inchanters, and the like, those transformations and deceptions of the sight are even in the order of natural consequences, from the pre-supposed and allowed power of such characters to operate them. At the same time the rules of probability must even there be observed. Nor is it amiss to be very sparing and reserved in the composition of those dances, grounded on the introduction of purely imaginary beings, such as the allegorical impersonation of the moral Beings, whether the Virtues or the Vices. Unless the invention is very interesting indeed, the characters distinctly marked, and the application very just and obvious; their effect is rarely answerable to expectation, especially on the audiences of this country. The taste here for those airy ideal characters is not very high, and perhaps not the worse for not being so.
