Now my task in this last chapter is a more delightful one than if I were the usual solicitor of fiction, come to inform the poor-but-honest newsboy that he is a royal duke. It is my privilege to comfort many of the comfortless by revealing to them how and why they are--or may be--masters of an art as indispensable as the arts which they now regard so wistfully. I mean the art of master-making--the art of being a master by proxy. To be specific, let us single out one of the arts and see what it means to master it by proxy. Suppose we consider the simple case of executive music. In a book called "The Musical Amateur" I have tried to prove (more fully than is here possible) that the reproduction of music is a social act. It needs two: one to perform, one to appreciate. Both are almost equally essential to a good performance. The man who appreciates a musical phrase unconsciously imitates it with almost imperceptible contractions of throat or lips. These contractions represent an incipient singing or whistling. Motions similar to these, and probably more fully developed, are made at the same time by his mind and his spirit. The whole man actually feels his way, physically and psychically, into the heart of the music. He is turned into a sentient sounding-board which adds its own contribution of emotion to the music and sends it back by wireless telegraphy to the performer. When a violinist and a listener of the right sort meet for musical purposes, this is what happens. The violinist happens to be in the mood for playing. This means that he has feelings which demand expression. These his bow releases. The music strikes the listener, sets him in vibration as if he were a sounding-board, and rouses in him feelings similar to those of the violinist. Enriched by this new contribution, the emotional complex resounds back to the violinist, intensifying his original "feeling-state." In its heightened form it then recoils back to the appreciator, "and so on, back and forth, growing in stimulating power at each recoil. The whole process is something like a hot 'rally' in tennis, with the opponents closing in on each other and the ball shuttling across the net faster with every stroke as the point gains in excitement and pleasure. 'Social resonance' might be a good way of describing the thing." This, briefly told, is what passes between the player of music and his creative listener. In application this principle does not by any means stop with performing or composing music or with the fine arts. It goes on to embrace more things in heaven and earth than are dreamed of in the fiddler's or in any other artist's philosophy. Perhaps it is not too much to say that no great passion or action has ever had itself adequately expressed without the cooeperation of this social resonance, without the help of at least one of those modest, unrecognized partners of genius, the social resonators, the masters by proxy.
