The comments on "Tan Yue" performed by erhu player Sun Huang are only admirable. "Tan Yue", also known as "Tan Liu", is a famous erhu piece composed by Mr. Sun Wenming in 1951. Sun Huang's "Playing Music" uses the low-pitched erhu to imitate the sound effect of the small sanxian. The erhu without a thousand pounds has a wider range and a more melodious bass, which makes people comment only in admiration.
