The bo (simplified Chinese: 钹; traditional Chinese: 鈸; pinyin: bo; Wade–Giles: po) is a percussion instrument originating in China, a type of cymbals. It consists of two plates that are clashed together. It is a concussion idiophone.
The Metropolitan Museum of Art has one from nineteenth century China. Both parts have a diameter of 56.5 centimeters.
The cymbal in the rock drumset China cymbals may be based on the bo, but is hit with a drumstick instead.
