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.
Flute Quartet No. 3 (Mozart) Wolfgang Amadeus Mozart's Flute Quartet No. 3 in C major, K. 285b, is the last of three quartets for the amateur flautist Ferdinand De Jean. Mozart's manuscript designates this work for flute, violin, viola and basso. Despite following directly after the first two flute quartets in the Köchel catalogue, the Quartet in C was almost certainly written a few years later, likely sometime between the years 1781 to 1782.
