konghou (箜篌) is an ancient Chinese harp. The konghou went extinct sometime in the Ming Dynasty, but was revived in the 20th century. The modern instrument does not resemble the ancient one.
The main feature that distinguishes the modern konghou from the Western concert harp is that the modern konghou's strings are folded over to make two rows, which enables players to use advanced playing techniques such as vibrato and bending tones. The two rows of strings also make it suitable for playing swift rhythms and overtones.
The wo-konghou, or horizontal konghou, was first mentioned in written texts in the Spring and Autumn period . or vertical konghou first appeared in the Eastern Han Dynasty ). The phoenix-headed konghou was introduced from India in the Eastern Jin Dynasty
