The art of music is so deep and profound that to approach it very seriously only is not enough. One must approach music with a serious rigor and, at the same time, with a great, affectionate joy.
Art is not emotion. Art is the medium in which emotion is expressed.
Great art likes chains. The greatest artists have created art within bounds. Or else they have created their own chains.
Without a strong cup to carry the emotion, it is only a curiosity. Great art can come to us only in strong cups. Without emotion, there is nothing to carry.
