The exact way in which _original_ ideas come into the mind is, of course, a mystery in music as in literature. Every genius passes through a period of apprenticeship, in which he _assimilates_ the discoveries of his predecessors, reminiscences of which make up the bulk of his early works. Everybody knows how Mozartish, _e.g._, Beethoven's first symphony is, and how much in turn Mozart's early works smack of Haydn. Gradually, as courage comes with years, the gifted composer sets out for unexplored forests and mountain ranges, attempting to scale summits which none of his predecessors had trod. I say, as courage comes, for in music, strange to say, it requires much courage to give the world an entirely new thought. An original composer needs not only the courage that is common to all explorers, but he must invariably come back prepared to face the accusation that his new territory is nothing but a howling wilderness of discords. This has been the case quite recently with Wagner, as it was formerly with Schumann, Beethoven, Mozart, the early Italian composers, and many others, including even Rossini, who certainly did not deviate very far from the beaten paths. Seyfried relates that when Beethoven came across articles in which he was criticised for violating established rules of composition, he used to rub his hands gleefully and burst out laughing. "Yes, yes!" he exclaimed, "that amazes them, and makes them put their heads together, because they have not seen it in any of their text-books." Fortunately for their own peace of mind, the majority of the minor composers never get beyond a mere rearrangement of remembered melodies and modulations. Their minds are mere galleries of echoes. They write for money or temporary notoriety, and not because their brains teem with ideas that clamor for utterance. The pianist Hummel was one of this class of composers. But whatever his short-comings, he had at least, as Wagner admits, the virtue of frankness. For when he was asked one day what thoughts or images he had in his mind when he composed a certain concerto, he replied that he had been thinking of the eighty ducats which his publisher had promised him! Yet even the greatest composers cannot always command new thoughts at will, and it is therefore of interest to note what devices some of them resorted to rouse their dormant faculties. Weber's only pupil, Sir Julius Benedict, relates that Weber spent many mornings in "learning by heart the words of 'Euryanthe,' which he studied until he made them a portion of himself, his own creation, as it were. His genius would sometimes lie dormant during his frequent repetitions of the words, and then the idea of a whole musical piece would flash upon his mind, like the bursting of light into darkness."
