The musician, then, being at the basis of all his ?sthetics, all his theories of opera and drama, the question arises, what sort of a musician was he? He was the spiritual son of Beethoven; a remoter ancestor was Bach. This is the cardinal fact in the psychology of Wagner; and it will need to be examined in all its bearings.

Wagner was one of those dynamically charged personalities after whose passing the world can never be the same as it was before he came—one of the tiny group of men to whom it is given to bestride an old world and a new, but to sunder them by a gulf that becomes ever more and more impassable; one of the very few who are able so to fill the veins of a whole civilisation with a new principle of vitality that the tingle of it is felt not only by the rarer but by the commonest spirits—some new principle from which, whether a man likes it or not, he will find it impossible to escape. Wagner is probably the only figure in the whole history of music of whom this can be said. Bach created no such upheaval. He counts for next to nothing in the music of his own day and that of the two generations that followed him. He did not make a new world in music: rather had a new world to be made before men\'s eyes were competent to take the measure of that towering stature, or men\'s hearts quick enough with life to respond to the profound humanism of that great soul. We were not fit for Bach until Beethoven and Wagner—and Wagner, perhaps, even more than Beethoven—made us so. Beethoven, again, had it not been for Wagner, would probably not have meant as much to us as he does now, or become the fertilising force he is in modern music; and even that fertilisation is effected through Wagner\'s work rather than along lines in continuation of Beethoven\'s own. If anyone doubts this, let him ask himself what new spirit of enduring vitality and power of propagation has come out of the classical symphony pure and simple. Not Brahms, assuredly, great as he is: "arrested development" is written large upon the forms and the ideas of all the music that has come out of Brahms\'s symphonies as clearly as upon those symphonies themselves. So far as modern instrumental music has developed in humanity of utterance or in breadth of structure, it is from assimilating from Beethoven, through Wagner, just the urgent poetic spirit that Brahms passed by in Beethoven,—the spirit of which Beethoven was himself only dimly conscious, but which Wagner from the beginning saw to be inherent in him, and which he distilled from the general tissue of Beethoven\'s work and used in a new form for magical results of his own. The only explosive force in music at all comparable in general to Wagner was Monteverdi. But Monteverdi came a couple of hundred years too soon. The world was not ready for him—it is hardly a paradox to say that he was not ready for himself—and his explosion mostly spent itself in a desert. Wagner had first-rate luck in this as in everything else in his life that really mattered to him as an artist; not only had he the right dynamic spark within him, but he was born into an atmosphere made electrically ready by the passionate soul\'s cry of Beethoven. The explosion came—a cataclysmic upheaval, leading to a new geological formation, as it were, in music, new geographical delimitations, a new fauna and flora.

He had access to Beethoven\'s heart: and from the blood in Beethoven\'s veins ............
