The pipa (Chinese: 琵琶; pinyin: pípá) is a plucke Chinese string instrument. Sometimes called the Chinese lute, the instrument has a pear-shaped wooden body. It has been played for nearly two thousand years in China, and belongs to the plucked category of instruments (弹拨乐器/彈撥樂器). Several related instruments in East and Southeast Asia are derived from the pipa; these include the Japanese biwa, the Vietnamese đàn tỳ bà, and the Korean bipa. The Korean instrument is the only one of the three that is no longer used. Attempts to revive the instrument have failed, although examples survive in museums.
