The "Dance of the Sugar Plum Fairy" is one of the most famous numbers in "The Nutcracker". It was written for the "celesta". This instrument was new at the time the dance was written. It looks like a small piano, but it sounds like bells. Tchaikovsky discovered the "celesta" in Paris in 1891 while making a journey to the United States. His publisher purchased one and promised to keep the purchase a secret. Tchaikovsky did not want Rimsky-Korsakov or Glazunov to "get wind of it and ... use it for unusual (different, strange) effects before me." Petipa wanted the Sugar Plum Fairy's music to sound like drops of water splashing in a fountain. Tchaikovsky thought the "celesta" was the instrument to do this. The original steps for the dance are unknown. Antonietta Dell'Era was the first to dance the part of the Sugar Plum Fairy. The character has very little dancing to do so Dell'Era put a gavotte by Alphonse Czibulka into the ballet. She then had something more to do.
