While the ordinal of 0 mostly finds use in communities directly connected to mathematics, physics, and computer science, there are also instances in classical music. The composer Anton Bruckner regarded his early "Symphony in D minor" to be unworthy of including in the canon of his works, and he wrote 'gilt nicht' on the score and a circle with a crossbar, intending it to mean "invalid". But posthumously, this work came to be known as "Symphony No. 0 in D minor", even though it was actually written after "Symphony No. 1 in C minor". There is an even earlier "Symphony in F minor" of Bruckner's that is sometimes called "No. 00". The Russian composer Alfred Schnittke also wrote a Symphony No. 0.
