A single instrument able to convey very powerful feelings.
The melody you used, every single note gives quite an "ethnic" flavor, they do remind me of Nordic folk music. Actually, I like even the little glitches and pops here and there, something to break the monotony by introducing non-conventional electronics, although probably pretty involuntary. As I'm writing this, it's probably the fourth time I'm listening to this track. No regrets. ;D
