Richard Wagner (1813-1883) is by far the most important figure in the history of modern opera. With regard to the intrinsic beauty of his works, and the artistic value of the theories upon which they are constructed, there have been, and still are, two opinions; but his most bigoted opponents can scarcely refuse to acknowledge the extent of the influence which he has had upon contemporary and subsequent music--an influence, in fact, which places him by the side of Monteverde and Gluck among the great revolutionists of musical history. As in their case, the importance of his work rests upon the fact that, although to a certain extent an assimilation and development of the methods of his predecessors, it embodied a deliberate revolt against existing musical conditions.
From one point of view Wagner's revolt is even more important than that of either of his forerunners, for they were men who, having failed to win success under the existing conditions of music, revolted--so to speak--in self-preservation, while he was an accomplished musician, and the author of a successful work written in strict accordance with the canons of art which then obtained. Had Wagner pleased, there was nothing to hinder his writing a succession of 'Rienzis,' and ending his days, like Spontini, rich and ennobled. To his eternal honour he rejected the prospect, and chose the strait and narrow way which led, through poverty and disgrace, to immortality. In spite of the acknowledged success of 'Rienzi,' Wagner's enemies were never tired of repeating that, like Monteverde, he had invented a new system because he could not manipulate the old. It seems hardly possible to us that musicians could ever have been found to deny that the composer of 'Die Meistersinger' was a consummate master of counterpoint. Fortunately the discovery of his Symphony in C finally put an end to all doubts relative to the thoroughness of Wagner's musical education. In this work, which was written at the age of eighteen, the composer showed a mastery of the symphonic form which many of his detractors might have envied. The fact is, that Wagner was a man of a singularly flexible habit of mind. He was a careful student of both ancient and modern music, and a study of his works shows us that, so far from despising what had been done by his predecessors, he greedily assimilated all that was best in their productions, only rejecting the narrow conventions in which so many of them had contentedly acquiesced. His music is the logical development of that of Gluck and Weber, purified by a closer study of the principles of declamation, and enriched by a command of orchestral resource of which they had never dreamed.
