On every side this sort of instruction goes on. One hears glib statements on the lips of uninstructed persons about child psychology, “second” brain, and so forth. A pupil is asked to listen to a phrase of music and then tell the teacher what “comes through.” We must remember that art is discipline and that there is no real liberty except under law. We want children to use their minds accurately and to have control of their bodies, but this use and this control can only come through definite and regulated effort. Gropings in the dark, detached and illusive pursuits of the will-o’-the-wisps of education will never accomplish our purpose. IV. WHAT SHOULD CHILDREN SING? But even these artificial and false methods are less harmful to children than are the poor, vapid, and false songs by means of which their taste is slowly and surely disintegrated. Now the nature of music is such that many people are unable to see why one child’s song is better than another. There is a considerable number of people having to do with children’s music who seem quite incapable of distinguishing between a really beautiful folk-song and a trivial copy of one. Long association with the latter has produced the inevitable result. Only one argument can be brought to bear on such persons, an argument having nothing to do with æsthetics--namely, that the current music for children of one generation is inevitably displaced by that of the next, whereas the same folk-songs are continually reproduced, and are sung by increasing generations of children the world over. Any musician can string together in logical sequence a series of notes to fit a verse of simple poetry--almost every musician has; any poet can put together simple and easily understood verses; but the hand of time sweeps them away to oblivion. Out of the depths of simple hearts, in joy or sorrow or privation, as a balm to toil and labor, as a cry from a mother’s heart, in battle, in moments of religious exaltation--wherever and whenever the depths are stirred, song springs forth. A composer can express only what is in him; his limitations are as confining as are those of every other artist. Dickens could no more create a Clara Middleton than could Tschaikovsky a theme like that at the opening of the Ninth Symphony; and to suppose that the creation of a child’s song is a simple matter of putting notes together in a correct and agreeable sequence, is to misconceive the whole creative process.
