This is an interesting topic that centres around Natalia Dudinskaya and Konstantin Sergeyev's knowledge of Marius Petipa's choreography and the preservation of variations of his greatest dancers through personal recollections. Below is a video clip of Margarita Kulik dancing the alternative variation for Dulcinea that was made famous in the Kirov/Mariinsky production of Don Quixote. This is the variation that is danced today by Viktoria Tereshkina and Natalia Dudinskaya often performed it during her career in her own performances as Kitri. The origin of this variation dates back to the 19th century - it is one of the many variations created for the great Italian Prima Ballerina Assoluta Pierina Legnani. The music is by Riccardo Drigo and was created for Mlle. Legnani when Petipa revived The Little Humpbacked Horse under the title The Tsar Maiden for her in 1895. Years later, Natalia Dudinskaya would often resurrect variations of the great ballerinas of the Imperial Ballet and would perform them in place of the traditional variations; the variation in the video clip below is an example. When Dudinskaya became teacher, she would occasionally pass on these variations to her favourite students and Margarita Kulik was one such student.
