"According to Arnold Schoenberg, this superstition began with Gustav Mahler, who, after writing his Eighth Symphony, wrote Das Lied von der Erde, which, while structurally a symphony, was able to be 'disguised' as a song cycle, each movement being a setting of a poem for soloist and orchestra. Then he wrote his Ninth Symphony and thought he had beaten the curse, but died with his Tenth Symphony incomplete. In an essay about Mahler, Schoenberg wrote: 'It seems that the Ninth is a limit. He who wants to go beyond it must pass away. It seems as if something might be imparted to us in the Tenth which we ought not yet to know, for which we are not ready. Those who have written a Ninth stood too close to the hereafter.'"
