Mozart's "Zauberflöte"--"The Magic Flute"--is the oldest German opera holding a place on the American stage, though not quite 118 years old; but so far as my memory and records go, it has had but four performances in the original tongue in New York in a whole generation. There have been a few representations in English within this time and a considerable number in Italian, our operatic institutions being quick, as a rule, to put it upon the stage whenever they have at command a soprano leggiero with a voice of sufficient range and flexibility to meet the demands of the extraordinary music which Mozart wrote for the Queen of Night to oblige his voluble-throated sister-in-law, Mme. Hofer, who was the original representative of that character. The same operatic conditions having prevailed in New York and London for many years, it is not strange that English-speaking people have come to associate "The Magic Flute" with the Italian rather than the German repertory. Yet we have the dictum of Beethoven that it is Mozart's greatest opera, because in it his genius showed itself in so large a variety of musical forms, ranging from ditties in the folk-song style to figurated chorale and fugue, and more particularly because in it Mozart first disclosed himself as a German composer. By this Beethoven did not mean that Mozart had not written music before for a German libretto, but that he had never written German music before in an opera. The distinction is one more easily observed by Germans and critical historians than by the ordinary frequenters of our opera-houses. "Die Zauberflöte" has a special charm for people of German blood, which is both admirable and amiable. Its magnificent choruses are sung by men, and Germany is the home of the Männergesang; among the opera's songs are echoes of the Volkslied--ditties which seem to have been caught up in the German nurseries or plucked off the lips of the itinerant German balladist; its emotional music is heartfelt, warm, ingenuous, and in form and spirit free from the artificiality of Italian opera as it was in Mozart's day and as it continued to be for a long time thereafter. It was this last virtue which gave the opera its largest importance in the eyes of Otto Jahn, Mozart's biographer. In it, he said, for the first time all the resources of cultivated art were brought to bear with the freedom of genius upon a genuine German opera. In his Italian operas, Mozart had adopted the traditions of a long period of development, and by virtue of his original genius had brought them to a climax and a conclusion; but in "Die Zauberflöte" he "stepped across the threshold of the future and unlocked the sanctuary of national art for his countrymen."
