I often get told about nyckelharpas for sale. So if you're after a nyckelharpa and I've heard about it I'll post it here. Note though that I'm not endorsing or vouching for the instrument, just that I know about it and it's for sale. If you're interested in anything posted on this page, drop me a line and I'll pass your details on to the seller.
Instruments for sale:
Tenorharpa made by Alan Miller is being sold by Alan. Details on his website.
A tenorharpa is lower than a standard pitch nyckelharpa, but not as low as an oktavharpa.
So the strings are tuned: (low to high)
GDAE ie a violin one octave lower.
Nyckelharpa spotted in FaceBook Marketplace. Details here.
As usual - you should try it, I can't vouch for the instrument. But I'm sure it'll work.
