Esmeralda Tambourine Variation
music by Romualdo Marenco - the music is from his Sieba (1878), not from Pugni's score for La Esmeralda. The attribution is sometimes given as Drigo and is disputed.
A concert solo for Esmeralda, danced striking a tambourine, and one of the most performed female variations in international competition. It is not a number of the ballet La Esmeralda: a company staging that ballet does not dance it. See the linked works for the ballet it is named after and for the pas de deux the solo was originally built into.
