A final-year music student was required as part of his course to compose a symphony. Although otherwise a diligent student, he had no inspiration whatsoever for the task in hand. Then he remembered a piece of advice that his professor had given him a few terms earlier: ĎFind a symphony by a modern but not ultra-modern composer, and copy it out backwards - nobody will recognize ití. The student decided to follow this advice, butÖ which symphony to choose? Finally it dawned upon him: the professor himself had once written a symphony. It was unpublished, though the score was in the university music library. And so the student borrowed his professorís symphony, carefully wrote it out backwards, and prepared to sumbit his work.
It was then that the student realized that he had just produced a note-for-note copy of Sibeliusís Fourth Symphony.
