Pipa is a traditional plucked instrument in East Asia, with a history of more than two thousand years. The earliest musical instrument "Pipa" in China appeared around the Qin Dynasty. The word "Jue" in the word "Pipa" means "two jade collide and make a pleasant knocking sound", which means that it is a musical instrument that makes a sound by plucking the strings. Their names "Pi" and "Pa" are based on the right-handed skills of playing these instruments. In other words, pipa and arpeggio are the names of two playing techniques. The right hand plays the pipa forward and the right hand plays the arpeggio backward.
Before the Tang Dynasty, pipa was also a general term for all plucked instruments of the Pipa family in Chinese. Chinese pipa spread to other parts of East Asia and developed into Japanese pipa, Korean pipa and Vietnamese pipa.
