Chinese zither, or guqin, which is also called qin, peptachord, jade harp, banjo, and heptachord, is a seven-stringed plucked instrument with a history over 3,000 years. It belongs to silk string in Eight Notes (eight categories of musical instrument in ancient orchestra). It has a wide voice register, deep tone and a long lingering sound. It was originally called Qin (the pronunciation is the same as piano in Chinese) in ancient China and has been renamed as Guchin for distinguishing it from piano since 1920.
