TW- is that you playing in any of those vids? Nice post.
I was lent a "kit" dulcimer 30 years ago and I played it for about a year. I missed it and never had money to get one of my own, but I think some day I'll pick one up. They are an incessantly joyful instrument to play. There's a woman I work with who's husband builds guitars and dulcimers, and maybe I'll see if I can wangle one out of him.
