“Now, you see,” said Gambara, “this music is not written for misbelievers, nor for those who know not love. If you have never suffered from the virulent attacks of an evil spirit who shifts your object just as you are taking aim, who puts a fatal end to your highest hopes,--in one word, if you have never felt the devil’s tail whisking over the world, the opera of _Robert le Diable_ must be to you, what the Apocalypse is to those who believe that all things will end with them. But if, persecuted and wretched, you understand that Spirit of Evil,--the monstrous ape who is perpetually employed in destroying the work of God,--if you can conceive of him as having, not indeed loved, but ravished, an almost divine woman, and achieved through her the joy of paternity; as so loving his son that he would rather have him eternally miserable with himself than think of him as eternally happy with God; if, finally, you can imagine the mother’s soul for ever hovering over the child’s head to snatch it from the atrocious temptations offered by its father,--even then you will have but a faint idea of this stupendous drama, which needs but little to make it worthy of comparison with Mozart’s _Don Giovanni_. _Don Giovanni_ is in its perfection the greater, I grant; _Robert le Diable_ expresses ideas, _Don Giovanni_ arouses sensations. _Don Giovanni_ is as yet the only musical work in which harmony and melody are combined in exactly the right proportions. In this lies its only superiority, for _Robert_ is the richer work. But how vain are such comparisons since each is so beautiful in its own way! “To me, suffering as I do from the demon’s repeated shocks, Robert spoke with greater power than to you; it struck me as being at the same time vast and concentrated. “Thanks to you, I have been transported to the glorious land of dreams where our senses expand, and the world works on a scale which is gigantic as compared with man.” He was silent for a space. “I am trembling still,” said the ill-starred artist, “from the four bars of cymbals which pierced to my marrow as they opened that short, abrupt introduction with its solo for trombone, its flutes, oboes, and clarionet, all suggesting the most fantastic effects of color. The _andante_ in C minor is a foretaste of the subject of the evocation of the ghosts in the abbey, and gives grandeur to the scene by anticipating the spiritual struggle. I shivered.” Gambara pressed the keys with a firm hand and expanded Meyerbeer’s theme in a masterly _fantasia_, a sort of outpouring of his soul after the manner of Liszt. It was no longer the piano, it was a whole orchestra that they heard; the very genius of music rose before them. “That was worthy of Mozart!” he exclaimed. “See how that German can handle his chords, and through what masterly modulations he raises the image of terror to come to the dominant C. I can hear all hell in it!
