Pyotr Ilyich Tchaikovsky was a Russian composer whose works included symphonies, concertos, operas, ballets, chamber music, and a choral setting of the Russian Orthodox Divine Liturgy. Some of these are among the most popular theatrical music in the classical repertoire. He was the first Russian composer whose music made a lasting impression internationally, which he bolstered with appearances as a guest conductor later in his career in Europe and the United States. One of these appearances was at the inaugural concert of Carnegie Hall in New York City . Tchaikovsky was honored by Emperor Alexander III, and awarded a lifetime pension.
