If non-traditional means not-traditional-to-western-cultures...
It seems everyone got the gist of the question, what I meant by Non traditional, I meant uncommon, I guess. I am not
sure by what you mean by not-traditional-to-western-cultures. It used to be that not very many instruments were
invented in the USA, most arrived by boat, forced or otherwise then adapted locally. Many instruments "invented"
in the USA for example have precursors across the Atlantic. The piano, for example, is probably not traditional in some
Amazonian villages and their answer to my question could possibly be, "The Piano, It was a @#$% to get it here..."
I did not mean to be vague.
What prompted my question was the Hang Drum
It's like an inverted steel drum played by hand. Now there are several adaptations slit steel drums, hapi drums and so on.

I have wanted to get an ocarina too.
By the way, I was introduced to the Hurdy Gurdy Here:http://www.ted.com/talks/lang/eng/caroline_phillips_hurdy_gurdy_for_beginners.html
