Pyotr Ilyich Tchaikovsky (May 7, 1840 — November 6, 1893) was a Russian composer of the Romantic era. His wide ranging output includes symphonies, operas, ballets, instrumental and chamber music and songs.
He wrote some of the most popular concert and theatrical music in the 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.
The Sleeping Beauty is a ballet in a prologue and three acts. The music was by Pyotr Ilyich Tchaikovsky (his Opus 66). The score was completed in 1889, and is the second of his three ballets. The original scenario was conceived by Ivan Vsevolozhsky, and is based on Charles Perrault’s La Belle au bois dormant.
The premiere performance took place at the Mariinsky Theatre in St. Petersburg in 1890. The work is widely regarded as Tchaikovsky’s finest ballet score, and has become one of the classical repertoire’s most famous ballets.
