This Polska efter Röjås Erik is but one of many, many tunes attributed to the iconic fiddler from the village of Boda, province of Dalarna.
The dance commonly called Bodapolska is done to this kind of tune – an 8th-note polska with a little extra stress on the second beat of each measure, always an upstroke with the bow.
I became acquainted with this tune in Sweden in 1974, where I first heard it played as a hambo. The hambo is an old-time Swedish dance with a more even beat than a typical Bodapolska.
In Dalarna it is generally played as a Bodapolska, but is often played as a hambo around the country.
