Beauties succeed each other in swift and picturesque succession, fitting the dramatic order with a nicety which forces the highest praise of the critic. The march and the chorus marking the return of Valentine's regiment beat with a fire and enthusiasm to which the tramp of victorious squadrons might well keep step. The wicked music of Mephistopheles in the sarcastic serenade, the powerful duel trio, and Valentine's curse are of the highest order of expression; while the church scene, where the fiend whispers his taunts in the ear of the disgraced Marguerite, as the gloomy musical hymn and peals of the organ menace her with an irreversible doom, is a weird and thrilling picture of despair, agony, and devilish exultation. Gounod has been blamed for violating the reverence due to sacred things, employing portions of the church service in this scene, instead of writing music for it. But this is the last resort of critical hostility, seeking a peg on which to hang objection. Meyerbeer's splendid introduction of Luther's great hymn, "Ein' feste Burg," in "Les Huguenots," called forth a similar criticism from his German assailants. Some of the most dramatic effects in music have been created by this species of musical quotation, so rich in its appeal to memory and association. Who that has once heard can forget the thrilling power of "La Marseillaise" in Schumann's setting of Heinrich Heine's poem of "The Two Grenadiers?" The two French soldiers, weary and broken-hearted after the Russian campaign, approach the German frontier. The veterans are moved to tears as they think of their humiliated Emperor. Up speaks one suffering with a deadly hurt to the other, "Friend, when I am dead, bury me in my native France, with my cross of honour on my breast, and my musket in my hand, and lay my good sword by my side." Until this time the melody has been a slow and dirge-like stave in the minor key. The old soldier declares his belief that he will rise again from the clods when he hears the victorious tramp of his Emperor's squadrons passing over his grave, and the minor breaks into a weird setting of the "Marseillaise" in the major key. Suddenly it closes with a few solemn chords, and, instead of the smoke of battle and the march of the phantom host, the imagination sees the lonely plain with its green mounds and mouldering crosses.
