Two ritual musical instruments – a chime and a bell – are among the most eye-catching exhibits at the Hong Kong Palace Museum. Both date to 1761 during the Qing Dynasty. The chime (teqing), made of nephrite jade with gilded decorations, and the bell (bozhong), cast in gilded copper alloy, each belonged to separate sets of twelve instruments. Each set corresponds to the twelve months of the traditional Chinese calendar, with every instrument tuned to a distinct pitch in the traditional twelve-tone system.
