In 1870 his ballet "Coppélia" was produced. By 1884 it had been performed 100 times. Together with "La Sylphide" and "Giselle" it was one of the most popular of all ballets. The story is about a man who makes a mechanical doll. Another popular ballet he wrote was "Sylvia". His most successful opera was "Lakmé" which was first performed at the Opéra-Comique in 1883. It gives great opportunity for the main soprano, especially in the song called the "Bell Song". Musicians usually think "Lakmé" is his greatest work.
