Now, just as the feeling passes from the brain of the musician into the tips of his fingers, so it does with an artist. You will see him, as he tries to tell you about the beauty of something, circling his hand in the air, meanwhile curving his fingers and thumb, as if he were trying to grasp the beauty. It is an instinctive movement, due to his habit of expressing his conception with his hand. A sculptor will do much the same thing, only he is more apt to close his fingers and express his meaning with his thumb--the part of his hand that he uses most in modeling.
