Who was the composer of both the "Christmas Symphony" and "Symphony No.3"?
Symphony No. 2 (Penderecki) Polish composer Krzysztof Penderecki wrote his Symphony No. 2 during the winter of 1979–80. Sometimes referred to as the "Christmas Symphony" (quotations of the Christmas carol "Silent Night" occur repeatedly throughout the symphony), neither the score nor the parts (Schott Music, Mainz 45 791) make any reference to this moniker.
Piano Trio (Tchaikovsky) Pyotr Ilyich Tchaikovsky's Trio in A minor, Op. 50, 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. It is scored for piano, violin, and cello.
