The most famous discovery at the tomb is the large set of Bianzhong 編鐘, which required a cast of five members to be played, and were struck with wooden mallets to produce music. The bells are two-toned, producing two distinct tones when struck at the center or the side; this property is enabled because the bells have an almond-shaped cross-section. The bells cover a range of five octaves. The collection also contains a non-matching bell, a memorial to Marquis Yi from King Hui of Chu State, recording King Hui's rushed trip from the west to create the bell and attend the Marquis's funeral during the 56th year of King Hui's reign; the inscription on the bell dates the event to 433 BCE. The bells were inscribed with music notations that detailed the relationship among the pitch standards of Zeng, Chu and Zhou.
Other musical instruments in the ensemble include stone chimes. Various string instruments were also discovered in the tombs, including the twenty-five stringed se, ten-stringed qin and five-stringed zhu.
