But the music of which I have been speaking was never cradled, so to say, in the lap of science; although, in its strangely-fascinating sweetness, soulfulness, and perfect rhythmic flow, it has often quite disarmed the scientific critic. It is a kind of natural music. Until quite recently no attempt was made to write it out, and place its melodies upon the printed music-page. Slavery, of course, prevented that. And this vile system, although it could not stamp out the "vocal spark," the germ of great musical ideas, could still prevent such growth of the same, such elaboration, as would have been secured by education in a state of freedom. Yet, since the war, many of the religious slave-songs of the South, words and music, have been printed. It has been found that they are as subject to the laws of science as are others; that they were not, as many persons have supposed, merely a barbarous confusion of sounds, each warring, as it were, against the other. For a proof of this (if there be those who doubt), the reader is referred to the "History of the Jubilee Singers of Fisk University," in which he will find printed the music of many songs like those to which I have alluded. Thus have we considered, in part, the native minstrelsy of the South. Notwithstanding their lack of a scientific knowledge of music, colored men, as instrumentalists, have long furnished most of the best music that has been produced in nearly all of the Southern States. At the watering-places, orchestras composed of colored musicians were always to be found; in fact, at such places their services were considered indispensable. Many of them could not read music; but they seemed naturally full of it, and possessed a most remarkable faculty for "catching" a tune from those of their associates who learned it from the written or printed notes: in truth, the facility of all in executing some of the most pleasing music in vogue was so great, that, when these little orchestras played, it was almost impossible to discover the slightest variation from the music as found on the printed page.
