The history of the flat, sharp, and natural is not a dull record, but a tale full of stirring incidents. If my narrative does not succeed in engaging your interest, in stimulating your curiosity, and in now and then sending a thrill of excitement through you, I have failed to do justice to the noble subject of my choice. These remarks may lead you to suppose that I am going to speak of the human flats, sharps, and naturals of our profession. This, too, is, if not a noble, certainly an interesting subject; but it is not the one of which I intend to treat on this occasion. My subject is the origin, rise, and vicissitudes of the musical signs that raise and lower natural notes and restore raised and lowered notes to their natural state. No doubt most people would suspect such a history to be dull; but nothing is dull if only we go deep enough into it. The subject in question is certainly not an exception to this rule, which could be confirmed by the study of hundreds of the apparently dry details of our notation. It is with these details as with the humble constituents of society; with the flat, sharp, and natural as with those lowly neighbours of ours whose lives seem to us an unbroken level desert. How great is always our astonishment when chance allows us to get a glimpse of what is hidden behind the plain, prosaic exteriors, and we discover loves and hates, hopes and disappointments, joys and sorrows, aspirations, successes, and failures—in short, at least as much romance as in the lives of the great and mighty. Well, let us try to get a glimpse of what is hidden behind the plain exteriors of the humble friends now under consideration.
