Tchaikovsky introduced the "celesta" to Russian music lovers on 19 March 1892 when the "Nutcracker Suite" was performed for the Russian Musical Society in St. Petersburg. The instrument is forever identified with the Sugar Plum Fairy. It is heard in other parts of Act 2 of "The Nutcracker" besides the Sugar Plum Fairy's dance. The "Dance of the Sugar Plum Fairy" is one of the ballet's best known musical numbers. It is often "jazzed up" for television commercials at Christmas time.
