It remains a popular folk dance in many European countries, and it is performed also in Poland, Germany, Austria, Slovenia, Switzerland, Finland and to a lesser extent in Latvia, Lithuania, the Netherlands, Hungary, Italy, Ukraine, Romania, Belarus, Russia, and Slovakia. Local varieties of this dance are also found in the Nordic countries, the United Kingdom, Ireland, Latin America and the United States. It is a fast dance. Its basic step consists of a preparatory hop followed by a chasse done first to the left and then to the right. It is danced to music written in 2/4 time with the first beat more heavily accented.
