Symphony in D minor, WAB 100

According to the conductor Georg Tintner, this lack of confidence in the work arose from a question by the puzzled conductor of the Vienna Philharmonic Orchestra, Felix Otto Dessoff, who asked Bruckner, "Where is the main theme?" The symbol "∅" was later interpreted as the numeral zero and the symphony got the nickname Die Nullte ("No. 0"). In the words of David Griegel, "Like many other composers, I believe Bruckner was merely being too self-critical, and the unnumbered symphonies are also works worthy of our enjoyment".
