I have alluded already to the fact that, perhaps because of the part of actual participating work which it entails, music is the art which has most share in life and of life, nowadays. It seems probable therefore that its especial mission may be to keep alive in us the feeling and habit of art, and to transmit them back to those arts of visible form to which it owes, perhaps, the training necessary to its own architectural structure and its own colour combinations. Compared with the arts of line and projection, music seems at a certain moral disadvantage, as not being applicable to the things of everyday use, and also not educating us to the better knowledge of the beautiful and significant things of nature. In connection with this kind of blindness, music is also compatible (as we see by its flourishing in great manufacturing towns) with a great deal of desecration of nature and much hand-to-mouth ruthlessness of life. But, on the other hand, music has the especial power of suggesting and regulating emotion, and the still more marvellous faculty of creating an inner world for itself, inviolable because ubiquitous. And, therefore, with its audible rhythms and harmonies, its restrained climaxes and finely ordered hierarchies, music may discipline our feelings, or rather what underlies our feelings, the almost unconscious life of our nerves, to modalities of order and selection, and make the spaceless innermost of our spirit into some kind of sanctuary, swept and garnished, until the coming of better days.
