I know this is a violin forum, but the Erhu is just like one and sounds beautiful. It`s rather and interesting instrument. Go here and let me know what you think...I think the Erhu is very nice and almost imitates human voice and feelings.

Here is the general site of a famous Erhu player, Karen Han. There is also some general information on the Erhu.
