My object in writing all this about the form and substance of the symphony, and in drawing comparisons between it and the novel or poetry, has not been to lead my readers to understand music through the other arts, for _by themselves_ such comparisons are of small value. I have dwelt on these common characteristics of the arts because they exist, because they illuminate each other, and at the same time because they are too little considered. The only way to understand music is to practice it, or, failing that, to hear it under such conditions as will permit a certain opportunity for reflection. We are incapable of understanding symphonic music chiefly because we have so little practice in doing so. An occasional symphony concert is not enough. How shall this difficulty be overcome? There is a natural way out, and it consists in what is called “chamber music.” A piece of chamber music is a sort of domestic symphony. A string quartette, a pianoforte or violin sonata, a trio, quartette, quintette, etc.,--these are all little symphonies; the form is almost identical, the same devices of rhythm, melody, harmony, counterpoint, and so forth, are employed. In chamber music paucity of idea cannot be covered up by luxury of tone color; everything is exposed; so that only the greatest composers have written fine music in this form. Now, if in every community there were groups of people who played chamber music together, and if these would permit their friends to attend when they practice, the symphony would soon find plenty of listeners. Such rehearsals would give an opportunity to hear difficult passages played over and over again; there would be time for discussion, and, above all, for reflection. Every town and village should have a local chamber-music organization giving occasional informal concerts. Under these circumstances a sympathetic intimacy would soon be established between the performers and listeners and the music itself. The inevitable and indiscriminate pianoforte lesson is an obstacle to this much desired arrangement. Some of our children should be taught the violin or the violoncello in preference to the pianoforte. Then the family circle could hear sonatas for violin and pianoforte by Bach, Mozart, Beethoven, or Brahms, and would accomplish what years of attendance at symphony concerts could not bring about. Chamber music has the great advantage of being simple in detail; one can easily follow the four strands of melody in a string quartette, whereas the orchestra leaves one breathless and confused. The practice of chamber music by amateurs would be one of the very best means of building up true musical taste. I cannot dwell too insistently on the fact that the majority of those people who do not care for such music would soon learn to care for it if they had opportunities to listen to it under such conditions as I have described. The argument proves itself, without the evidence--plentiful enough--of individuals
