The polka also migrated to the Nordic countries where it is known by a variety of names in Denmark (galopp, hopsa), Estonia (polka), Finland (pariisipolkka, polkka), Iceland, Norway (galopp, hamborgar, hopsa/hopsar, parisarpolka, polka, polkett, skotsk) and Sweden (polka). The beats are not as heavy as those from Central Europe and the dance steps and holds also have variations not found further south. The polka is considered a part of the gammeldans tradition of music and dance. While it is nowhere near as old as the older Nordic dance and music traditions, there are still hundreds of polka tunes in each of the Nordic countries. They are played by solo instrumentalists or by bands/ensembles, most frequently with lead instruments such as accordion, fiddle, diatonic accordion, hardingfele and nyckelharpa.
