So there I was, surfing around YouTube, listening to Finnish accordion music, when I came across a video featuring a most interesting instrument, apparently called a nyckelharpa. Check it out:
I consulted Wikipedia. The internets know everything, right?
A nyckelharpa (literally “key harp”, plural nyckelharpor or sometimes keyed fiddle) is a traditional Swedish musical instrument. It is a string instrument or chordophone. Its keys are attached to tangents which, when a key is depressed, serve as frets to change the pitch of the string.
The nyckelharpa is similar in appearance to a fiddle or the bowed Byzantine lira. Structurally, it is more closely related to the hurdy gurdy, both employing key-actuated tangents to change the pitch.
I learned something today….and now you know about nyckelharpas too. I confess I find unusual musical instruments fascinating.

Check out this website http://www.leventdunord.com/ for a French Canadian Folk band called Le Vent Du Nord. One of the members plays the Hurdy Gurdy. We’ve seen them twice in concert and LOVE their music. A sample of 3 songs from their album La Part Du Feu is available for you to hear. That album won them a Juno Award. The accordion music is great too.
