Yet if dancing demanded nothing more than physical effort and mental application, it could not claim the seriousness of art. The dexterous execution of a number of intricate steps has no more value than that of any other _tour de force_. Soulless dancing has as little power to move the spectator as the feats of a clever acrobat. There can be no great dancing without emotion. Unless the dancer has the capacity for unusual emotion, and is also gifted with the power of emotional expression, which is the beginning and end of all great dancing, the performance never rises to anything more inspiring than a dreary and unpleasing display of mechanical accomplishment. If the dancer has nothing in her to express, she dances in vain. Great dancing demands deep sensibility and a subtle responsiveness to the strong rhythms of life, together with the power of translating these emotions into beauty of bodily movement. Dancing can be taught just as much and just as little as any other art. The great dancer is born. But probably the seriousness of great art has been denied to dancing because of a common misapprehension as to what that seriousness consists in. It is almost always assumed that the seriousness of art depends upon its subject-matter. Serious art, it is supposed, must have a “message.” It must be concerned with actual problems, social or religious. It must in some way be oppressed with the burden of contemporary life. But an art which has nothing to say, no conundrums to ask, no solutions to offer--what claim can that have upon our serious attention? It is forgotten that it is not the subject that makes art serious or trivial, but the mood. There are problem pictures over which the public wrinkles its brows that are frivolous as a picture post-card from the point of view of art. And there are pictures of the bric-à-brac of a room, or a table spread for a meal, that are as grave as tragedy. It all depends upon the quality of the emotion that has gone to the making of them. The dance expresses the most serious thing in life--that is, ecstasy. All dull things are trivial. Art which has only the interest of contemporary problems is ephemeral, for when the problem is solved, the interest vanishes. The dance is the expression of the moods, and the moods are eternal. It has its source in passion, and where there is passion there is life at its utmost and seriousness at its highest.
