An associate of well-known Nordic music group Groupa from 1982 until 1987, Leif Stinnerbom is a expert from the Varmland dance music custom. Although he in the beginning performed Swedish latfiol, a forerunner from the Hardanger fiddle with two understrings, he turned to a viola d’amour design device with five playing strings and five resonance strings after developing Groupa with long-time friend and fiddler Mats Eden. Drawn together in the first 1970s by their shared desire for musical origins, Stinnerbom and Eden gathered many music from farmer and musician Oskar Andersson (1898-1986). In the past due ’70s they released an record of Varmland’s traditional folk music. Stinnerbom’s musical legacy continues to be inherited by his kid, Magnus Stinnerbom, who performs within a duo, Harv, with Daniel Sarden-Warg, and with Nordic folk group Hedningarna.
