Looking at all the instruments, I'm completely dumbstruck by the fact there's no bagpipes.
After all, they are the most rustic and ubiquitous instrument ever. Pretty much every agricultural society with tanned animal hides and wood has found a way to create bagpipes of some kind. It doesn't get much simpler than a watertight bag and a wooden reed.
I play bagpipes IRL and would be glad to give some advice about how to implement them.
