This might be the coolest thing you'll see today!! Nyckelharpa looks like it wandered out of a medieval manuscript. It's Swedish, bowed, with keys that stop the strings. It's been around since the 14th century. Arn Andersson (itsarnandersson) playing for us and he's rocking it 🔥 @xmuse_ #globalmuseum #musicalinstruments #music
