Of all the operas of the past century, our present public has not seen or even heard of one, with the exception of "The Magic Flute," and less probably "Don Juan." This is bad enough; but if we look at works belonging to the first part of the nineteenth century, we find the same state of affairs. The operas of Spontini, Rossini, most of Meyerbeer's, even Weber's "Freischuetz," have passed away, seemingly never to return. Even "Cavalleria Rusticana," of recent creation, is falling rapidly into oblivion. Thus the opera comique early disappeared in favour of the romantic opera and the operetta. The former has already nearly ended its career, and the latter has descended to the level of mere farce. In the course of time, these opera forms become more and more evanescent; for the one-act opera of miniature tragedy, which is practically only a few years old, is already almost extinct. And yet this art form has vastly more hold on the public than other music destined to outlive it. The fact is, that music which is tied down to the conventionalities and moods of its time and place can never appeal but to the particular time and mood which gave it birth. (Incidentally, I may say the same of music having its roots in the other peculiarities of folk song.) Now the writers of these operas were great men who put their best into their work; the cause of the failure of these operas was not on account of the music, but the ideas and thoughts with which this music was saddled. What were the books which people read and loved in those days (1750-1800), that is, books upon which operas might be built? In England we find "The Castle of Otranto," "The Mysterious Mother," etc., by Horace Walpole. Now Macaulay says that Horace Walpole's works rank as high among the delicacies of intellectual epicures as the Strasburg pie among the dishes described in the _Almanach des Gourmands_. None but an unhealthy and disorganized mind could have produced such literary luxuries as the works of Walpole. France had not yet recovered from the empty formalism of the preceding century, Bernardin de St. Pierre was a kind of colonial Mlle. Scudery, and Jean Jacques Rousseau, one of the sparks which were to ignite the French Revolution, writes his popular opera to the silly story of "The Village Soothsayer." Had not Gluck written to the classics he would have had to write "a la Watteau." In Germany, conditions were better; for the so-called Romantic school had just begun to make headway. In opera, however, this school of Romanticism only commenced to make itself felt later, when we have a crop of operas on Fouque's "Undine" as well as "Hofmann's Tales."
