This question comes up especially in connection with certain adjuncts to a music collection--pianola rolls and phonograph records. These are both of great aid in assisting the public to understand the language of music, which they must do before they learn to read it. They may be profitably used, of course in connection with reading, and yet the pleasure of following a piano player or a phonograph with the printed score seems to be known to few. Every library must judge for itself whether it can afford to put money into these adjuncts but in most cases it is unnecessary to do so, it being easy to get the rolls and records by donation. In doing this at my own library I have been struck with the trivial or so-called “popular” character of most of the rolls received. I am told, also that those who borrow them (and they have gone out “like hot cakes”) are largely persons who have not visited the library before. I believe that this sort of music is popular not because it is trivial or “trashy”, but because it is easy to understand. There is some music that is both good and easy--easy to understand and easy to read. Schumann’s Album for the young will occur to anyone. The compositions of Ludwig Schytte are modern examples. But the general impression that good music is difficult both to read and appreciate--is “high-brow”, in fact; and that easy music is always trivial and poor, is a deduction, I am afraid from experience. It is certainly not in the nature of things. However, so long as we want easy music, both to hear and to read, and a good deal of it is trashy, I can see nothing to do but to use the trashy music. With the music rolls triviality is all we have to object to--the ceaseless repetition of the same phrases and harmonies. We must remember, however, that these are not boresome to the beginner. It takes a good deal of repetition to make one tired of a musical phrase. And there is absolutely no question of active badness here--only of worthlessness. When we come to phonograph records, however, we encounter something different. So far as these are purely musical, what has been said of the music rolls applies to them also, but many of them are vocal, and the words are often far below library standard. When a record is rejected for its words, the music, of course, must go with it, although as music it may be quite unexceptionable.
