If, while speaking to you, I remained as still as a statue, my words would have had much less effect than they can have when accompanied by the gesture. If a person says, "Go away from here," and does not move, his words will not have much expression. If he moves his arms, they will have more expression. In India, the pupil is taught to sing with gestures. These take the place of notation, and guide him. A person might think, "Notation would be a much clearer method." But Indian music is so complicated that no notation can render it exactly. Then, too, the intervals are all filled up, and the movements of the hand and arm can express and guide more easily than any written signs.
