Peter Tchaikovsky (1840-1893) was a Russian composer. He composed a wide range of musical works, though his most popular music is probably from his ballets including Swan Lake, Sleeping Beauty and The Nutcracker. The circumstances of his tragic death are not fully understood.
Piotr Ilyitch Tchaikovsky (1840 - 1893) was born in Kamsko-Votkinsk, in the western Ural Vyatka province of Russia. He studied law in St. Petersburg and took music classes at the St. Petersburg Conservatory. There his teachers included the Russian composer and pianist Anton Rubinstein, from whom Tchaikovsky subsequently took advanced instruction in orchestration.
