For, once his period of apprenticeship passed, and all desire to write symphonies and chamber-music in the styles of Schumann and Mendelssohn and Brahms, to construct operas after the pattern of "Tannhaeuser" and "Parsifal" gone out of him, this slender, sleepy young Bavarian with the pale curly hair and mustaches had commenced to develop the expressive power of music amazingly, to make the orchestra speak wonderfully as it had never spoken before. Under his touch the symphony, that most rigid and abstract and venerable of forms, was actually displaying some of the novel's narrative and analytical power, its literalness and concreteness of detail. It was describing the developments of a character, was psychologizing as it had hitherto done only in conjunction with poetry or the theater. Strauss made it represent the inflammations of the sex illusion, comment upon Nietzsche and Cervantes, recount the adventures, somersaults and end of a legendary rascal, portray a hero of our time. He made all these intellectual concepts plastic in a music of a brilliance and a sprightliness and mordancy that not overmany classic symphonies can rival. Other and former composers, no doubt, had dreamt of making the orchestra more concretely expressive, more precisely narrative and descriptive. The "Pastoral" symphony is by no means the first piece of deliberately, confessedly programmatic music. And before Strauss, both Berlioz and Liszt had experimented with the narrative, descriptive, analytical symphony. But it was only with Strauss that the symphonic novel was finally realized.
