Schubert was the most omnivorous song composer that ever lived. He could hardly see a poem--good, bad, or indifferent, without being at once seized by a passionate desire to set it to music. He sometimes wrote half a dozen or more songs in one day, and some of them originated under the most peculiar circumstances. The serenade, "Hark, hark, the lark," for instance, was written in a beer garden. Schubert had picked up a volume of Shakespeare accidentally lying on the table. Presently he exclaimed, "Such a lovely melody has come into my head, if I only had some paper." One of his friends drew a few staves on the back of a bill of fare, and on this Schubert wrote his entrancing song. "The Wanderer," so full of original details, was written in one evening, and when he composed his "Rastlose Liebe," "the paroxysm of inspiration," as Grove remarks, "was so fierce that Schubert never forgot it, but, reticent as he often was, talked of it years afterward." These stories remind one of an incident related by Goethe, who one day suddenly found a poem spontaneously evolved in his mind, and so complete that he ran to the desk and wrote it diagonally on a piece of paper, fearing it might escape him if he took time to arrange the paper. In a word, Schubert _improvised with the pen_, and he seems to have been an exception to Schopenhauer's rule, that the greatest writers are those whose thoughts come to them before writing, and not while writing. Nevertheless, it must be admitted that much of the music which Schubert composed in this rapid manner is poor stuff; and although his short songs are generally perfect in their way, his longer compositions would have gained very much had he taken the trouble to think them out beforehand, or to revise and condense them afterward, which he very rarely did. With a strange perversity and persistency, musical students and the public have been led to believe that the surest sign of supreme musical inspiration is the power to dash off melodies as fast as the pen can travel. Weber relates in his autobiographic sketch that he wrote the second act of one of his early operas in ten days, and adds, significantly, that this was "one of the many unfortunate results of the wonderful anecdotes about great masters, which make a deep impression on youthful minds, and incite them to imitation."
