(Small correction: the Chinese equivalent to the koto is the zheng -- the qin is the ancestor of both instruments, as well as the Korean gayageum. The qin has no bridges at all, while the others do, usually moveable. One overtone to be aware of is that the qin was for over a millenium the instrument par excellence of the refined scholar-gentlemen, while the zheng was used for more popular music -- the qin being too quiet for ensemble use.)
