Triakel is a Swedish folk band. They mostly perform old Swedish folk songs, particularly those from the Jämtland area, but also include songs by contemporary folk artists.
Triakel was founded in 1995 by Emma Härdelin, Kjell-Erik Eriksson and Janne Strömstedt; Eriksson and Strömstedt had to perform together using only the fiddle and harmonium on New Year's Eve 1994 following a lost bet, and the performance was so successful that they decided to continue with the project. Härdelin, later on, joined the newly formed band as the singer, and the name "Triakel" was chosen after a long discussion.
