Pyotr Ilyich Tchaikovsky's Trio in A minor, Op. 50 for piano, violin, and cello was written in Rome between December 1881 and late January 1882. It is subtitled In memory of a great artist, in reference to Nikolai Rubinstein, his close friend and mentor, who had died on 23 March 1881.
The work's first version was completed by late January 1882.Private performances were held in March and April. The work underwent considerable revision before its premiere on October 30 at a quartet concert of the Russian Musical Society in Moscow. The piano soloist was Sergei Taneyev; the other performers are unknown.
