The pipa (琵琶, Pí Pá) is a four-stringed Chinese musical instrument, belonging to the plucked category of instruments. Sometimes called the Chinese lute, the instrument has a pear-shaped wooden body with a varying number of frets ranging from 12–26. Another Chinese 4 string plucked lute is the liuqin, which looks like a smaller version of the pipa.
The pipa appeared in the Qin Dynasty (221 - 206 BCE) and was developed during the Han Dynasty. It is one of the most popular Chinese instruments and has been played for nearly two thousand years in China. 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.
