Delibes appreciated the folk music of eastern Europe. He wrote both a Polish dance called the mazurka, and an Hungarian dance called the czardas for the ballet. Delibes's czardas was the first written for a ballet. Other ethnic music in the ballet include a Spanish bolero and a Scottish jig. Frantz has no solo dance in the original ballet because a woman played the part. A pas de deux for Frantz and Swanhilda was not possible for the same reason. The pas de deux now in the ballet was the addition of Marius Petipa. He put a pas de deux in the ballet when he rearranged the music for his 1884 St Petersburg production.
