Previously, we introduced a three-stringed lute, called the Sanxian, which is a common supplementary instrument in the folk performance of Beijing, so many say they feel nostalgia for old Beijing when hearing it. Today, instrumentalist Wang Yu joins us and shares how he puts effort into optimizing the electric Sanxian. His aim is to expand its volume, giving it a more powerful resonance. He also brings us several remarkable works played with the electric three-stringed lute.
