Full coverage: G20 Hangzhou Summit

A very beautiful and tranquil sound. Yesterday we talked about China's tea culture. Drinking Longjing tea and listening to traditional music, that's how the people of Hangzhou like to unwind.

Yes, and today we're going to talk a little about that traditional music and, more specifically, the Erhu....It's essentially a two-stringed bowed musical instrument, and is sometimes referred to in the West as the Chinese violin. It has a long history in China...

Yes Mike, it's said its origin dates back more than one thousand years ago.

It's the most prevalent of the Huqin family of traditional bowed string instruments used by various ethnic groups in China.

But let's not get ahead of ourselves here, we'll bring in an proper Erhu musician to tell us all we need to know... Zhou Shanshan, welcome!

Q1. Tell us about the instrument itself...what's its composition?

Q2. Are there any unusual features?

Q3. What is the most popular form of Erhu music in Hangzhou?
