Description: Pyotr Ilyich Tchaikovsky (May 7, 1840 [O.S. April 25] – November 6, 1893 [O.S. October 25]) was a Russian composer of the Romantic era. As his style developed, Tchaikovsky wrote music across a range of genres, including symphony, opera, ballet, instrumental, chamber and song. He wrote some of the most popular concert and theatrical music in the current classical repertoire, including the ballets Swan Lake, The Sleeping Beauty and The Nutcracker, the 1812 Overture, his First Piano Concerto, his last three numbered symphonies, and the opera Eugene Onegin.
