But for the new men, he is more than teacher. For them he is like the discoverer of a new continent. Through him they have come to find a new fashion of apprehending the world. Out of the paint-box that he opened, they have drawn the colors that make us see anew in their music the face of the earth. The tone-poems of Debussy and the ballets of Ravel and Strawinsky, the scintillating orchestral compositions of Strauss and Rimsky and Bloch, could scarcely have come to be had not Berlioz called the attention of the world to the instruments in which the colors and timbres in which it is steeped, lie dormant.
And so the large and powerful and contained being that, after all, was Berlioz has come to appreciation. For behind the fiery, the volcanic Berlioz, behind the Byronic and fantastical composer, there was always another, greater man. The history of the art of Berlioz is the history of the gradual incarnation of that calm and majestic being, the gradual triumph of that grander personality over the other, up to the final unclosing and real presence in "Roméo" and the "Mass for the Dead." The wild romanticist, the lover of the strange and the lurid and the grotesque who created the "Symphonic Fantastique," never, perhaps, became entirely abeyant. And some of the salt and flavor of Berlioz's greater, more characteristic works, the tiny musical particles, for instance, that compose the "Queen Mab" scherzo in "Roméo," or the bizarre combination of flutes and trombones in the "Requiem," macabre as the Orcagna frescoes in Pisa, are due his fantastical imaginings. But, gradually, the deeper Berlioz came to predominate. That deeper spirit was a being that rose out of a vast and lovely cavern of the human soul, and was clothed in stately and in shining robes. It was a spirit that could not readily build itself out into the world, so large and simple it was, and had to wait long before it could find a worthy portal. It managed only to express itself partially, fragmentarily, in various transformations, till, by change, it found in the idea of the Mass for the Dead its fitting opportunity. Still, it was never entirely absent from the art of Berlioz, and in the great clear sense of it gained in the "Requiem" we can perceive its various and ever-present substantiations, from the very beginning of his career.
