Pyotr Ilyich Tchaikovsky(May 7, 1840 [O.S. April 25] – November 6, 1893 [O.S. October 25]), often called Peter Ilich Tchaikovsky in English, was a Russian composer of the Romantic era. 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, as well as the 1812 Overture, his First Piano Concerto, his last three numbered symphonies, and the opera Eugene Onegin.
