Homegrown Plus: Northern Resonance

Share this post:

We’re continuing the Homegrown Plus series with Northern Resonance, a Scandinavian string trio rooted in traditional folk music. As usual for this series, you’ll find a concert video, an interview video, and a set of links to explore. Northern Resonance perform traditional and newly composed roots music on a previously untested combination of instruments: Swedish viola d’amore, hardanger fiddle and nyckelharpa. They combine Scandinavian music with explosive rhythms and grand chamber-like arrangements, taking folk music in a new direction. The members of Northern Resonance are highly skilled and accomplished musicians. The three instruments they play are all bowed stringed instruments, and they all make use of sympathetic strings. The sympathetic strings are not played by the musicians, but vibrate due to their proximity to the bowed strings, providing the “resonance” of the group’s name. With these unusual instruments and their lively tunes, Northern Resonance delighted our audience in the Whittall Pavilion on March 7, 2024. See the concert in the player below!

In the interview, I talked with all three members of the group about their careers as musicians. Jerker Hans-Ers (whose nickname is J.J.) is the group’s hardanger fiddler, and he explained how he took up the unusual Norwegian instrument.

Anna Ekborg Hans-Ers, who plays the viola d’amore, clarified that the Swedish version of the instrument has five strings (as opposed to seven on the classical version), while Petrus Dillner explained some of the mysteries of the keyed fiddle known as the nyckelharpa. We also touched on music education in Sweden, and the importance of music within families and regional traditions. And, of course, we discussed the band, their musical ideas, and the ups and downs of their career. See the interview in the player below!
