This book has a purpose, which is as simple as it is plain; and an unpretentious scope. It does not aim to edify either the musical professor or the musical scholar. It comes into the presence of the musical student with all becoming modesty. Its business is with those who love music and present themselves for its gracious ministrations in Concert-Room and Opera House, but have not studied it as professors and scholars are supposed to study. It is not for the careless unless they be willing to inquire whether it might not be well to yield the common conception of entertainment in favor of the higher enjoyment which springs from serious contemplation of beautiful things; but if they are willing so to inquire, they shall be accounted the class that the author is most anxious to reach. The reasons which prompted its writing and the laying out of its plan will presently appear. For the frankness of his disclosure the author might be willing to apologize were his reverence for music less and his consideration for popular affectations more; but because he is convinced that a love for music carries with it that which, so it be but awakened, shall speedily grow into an honest desire to know more about the beloved object, he is willing to seem unamiable to the amateur while arguing the need of even so mild a stimulant as his book, and ingenuous, mayhap even childish, to the professional musician while trying to point a way in which better appreciation may be sought.
