While I learned this Polska efter Johannes på Fjälle as a dance tune from Värmland, it may actually have originated in the neighboring province of Dalsland.
Johannes Svensson, better known as Johannes på Fjället (Johannes on the Mountain), was a popular fiddler in the neighborhood of Åmål, in Dalsland. He was a pawnbroker, born in 1820, and died in 1896.
Johannes played with lots of energy, usually using both feet to beat out time during his playing.
It is said that during a dance he would drink a cup of hard liquor, then breathe heavily into his fiddle “to put life into it”.
To the left is a video of me playing this polska. Notice that the opening notes are played using harmonics.
