This is a replica of a niu 钮 type two-tone bronze bell (bian zhong 編鐘). The original dates from the Spring and Autumn period and is in the collection of the National Palace Museum in Taipei. The bell is 'decorated with xing tai and coiling serpent designs' (description supplied by the National Palace Museum, Taipei). These bells are called 'two-tone' because they resound with a different tone when struck on the front and near the side. This one plays notes G#5 and B5.
