Only those who know the amount of labour involved in the composition of a five-act opera can measure the disappointment that must accrue to its author on finding that his work has failed to satisfy that agglomeration of entities known as the public. "La Reine de Saba" was more successful in Brussels than in Paris, and was well received in Germany, where, however, it has been dethroned in favour of the far finer work by Goldmark bearing the same name. It has also been heard in London under the title of "Irene." The opera of "Mireille," played for the first time at the Théâtre Lyrique in 1864, and introduced to the notice of the English public at Her Majesty's Theatre during the same year, is one of Gounod's most characteristic productions in the way that it illustrates the composer's qualities and defects perhaps as much as anything he has done. The poem upon which it is founded is the "Mireio" of Frederick Mistral, the celebrated Provençal poet. It is a pastoral, and as such necessarily appealed irresistibly to a composer who is never so happy as when treating a subject of this kind. The story is simple enough, and is thus condensed by Mons. Pagnerre, Gounod's clever biographer, to whose work I may refer those amongst my readers who seek for further information upon the composer's life: "A rich young girl, a poor young man, an ill-fated love; and death of the young girl through sunstroke." This tragic _dénouement_ was subsequently altered, and, according to the latest version of the opera, Mireille lives presumably to enjoy connubial bliss with her lover. Gounod has been less happy in his treatment of the essentially dramatic portions of the story than in those in which the lyrical element predominates. The general colour of his score is quite in keeping with a subject dealing with Provençale life, although it can scarcely be said that he has proved so successful in this respect as Bizet has in his music to Alphonse Daudet's "L'Arlésienne." Notwithstanding this, there are many charming pages in "Mireille," strongly marked with the composer's individuality, suggestive of warm sunshine and southern skies. If the opera is emphatically a disappointment when considered as a whole, if it absolutely fails to carry conviction as a musical drama, if it is full of contradictions of style and concessions to the vocalist, it may at least claim to be replete with melody of a refined nature and to contain several numbers that are always heard with pleasure. The melodious duet, "Oh Magali ma bien-aimée," has been one of the chief items in the _répertoire_ of tenors and sopranos during the last five-and-twenty years, and has been massacred by numberless amateurs in countless drawing-rooms.
