All this speak of these fancy key mechanisms is giving me the itch to find myself a more complex instrument. Although my finished instrument plays beautifully, I wouldn't mind trying out some new kinds, I have plenty of free time now to take on another restoration and if I do end up with another conical friend in my collection, believe me, the pictures and stories will be flooding in with lots of learning experience, I assure.
Kymarto, I too would be interested to hear more about your experience with the instrument. It's amazing how unique each tárogató seems to be, not only to work on but to play.
I'm interested in these odd "plateau key" instruments, I've seen pictures and have heard stories about them, but can't seem to find that there are very many of them. They at first reminded me too much like a wooden "soprano sax" to me from what I've seen of a few of them, but as I look at them more, they're growing on me like a chia pet and if I don't act soon I may have to shave.
