Polska (dance)

The polska (Swedish plural polskor) is a family of music and dance forms shared by the Nordic countries: called polsk in Denmark, polska in Sweden and Finland and by several different names in Norway in different regions and/or for different variants—including pols, rundom, springleik, and springar. The polska is almost always seen as a partner dance in  3
4-beat , although variants in 2
4 time and for two or more couples exist.

As suggested by the name the roots of the polska are often traced back to the influence of the Polish court throughout the northern countries during the early 17th century. (Polska also happens to be homonymous with the Swedish word for the Polish language.) This view is sometimes challenged by those who see earlier evidence of the musical tradition in Nordic visor or songs, that may have become grafted onto the newer foreign influences when the court dances began to filter out into the middle class and rural communities. Here and there also, a dance or a few dance melodies in triple meter have been found that may or may not be remnants of dances that the polska could have swallowed up.
