The Symphony No. 6 in E-flat minor, Op. 23 by Nikolai Myaskovsky was composed between 1921 and 1923. It is the largest and most ambitious of his 27 symphonies, and uses a chorus in the finale. It has been described as "probably the most significant Russian symphony between Tchaikovsky's Pathétique and the Fourth Symphony of Shostakovich". The premiere took place at the Bolshoi Theatre, Moscow on 4 May 1924, conducted by Nikolai Golovanov and was a notable success. The symphony was as successful abroad, being heard across Europe and America; it was programmed annually for 17 seasons by Frederick Stock in Chicago.
