The Sixth Symphony was originally planned to be a large-scale "Lenin Symphony" - a project which was often announced, but never materialised. Shostakovich had announced once in September 1938 that he was anxious to work on his Sixth Symphony, which would be a monumental composition for soloists, chorus and orchestra employing the poem "Vladimir Ilyich Lenin" by Vladimir Mayakovsky, but the declamatory nature of the poem made it difficult to set. He later tried to incorporate other literature about Lenin in his new symphony, but without success. In January 1939, he spoke about the Sixth Symphony in a radio address, with no mention of Lenin or any extramusical associations.
