Art is immeasurably greater than we are. If we are free and quiet, the poem, the music, the picture will carry us, so that we shall be surprised at our own expression; and when we have finished, instead of being personally elated with conceited delight in what we have done, or exhausted with the superfluous effort used, we shall feel as if a strong wind had blown through us and cleared us for better work in the future. Every genius obeys the true principle. It is because a genius is involuntarily under the law of his art that he is pervaded by its power. But we who have only talent must learn the laws of genius, which are the laws of Nature, and by careful study and steady practice in shunning all personal obstructions to the laws, bring ourselves under their sway. Who would wish to play on a stringed instrument already vibrating with the touch of some one else, or even with the last touch we ourselves gave it. What noise, what discord, with no possible harmonies! So it is with our nerves and muscles. They cannot be used for artistic purposes to the height of their best powers while they are tense and vibrating to our own personal states or habits; so that the first thing is to free them absolutely, and not only keep them free by constant practice, but so train them that they will become perfectly free at a moment's notice, and ready to respond clearly to whatever the heart and the mind want to express. The finer the instrument, the lighter the touch it will vibrate to. Indeed it must have a light touch to respond clearly with musical harmonies; any other touch would blur. With a fine piano or a violin, whether the effect is to be _piano_ or _fortissimo,_ the touch should be only with the amount of force needed to give a clear vibration, and the ease with which a fortissimo effect is thus produced is astonishing. It is only those with the most delicate touch who can produce from a fine piano grand and powerful harmonies without a blur. The response in a human instrument to a really light touch is far more wonderful than that from any instrument made by man; and bodily effort blurs just as much more in proportion. The muscles are all so exquisitely balanced in their power for co-ordinate movement, that a muscle pulling one way is almost entirely freed from effort by the equalizing power of the antagonizing muscle; and at some rare moments when we have really found the equilibrium and can keep it, we seem to do no more than _think_ a movement or a tone or a combination of words, and they come with so slight a physical exertion that it seems like no effort at all.
