A breakthrough excavation at a Liangzhu culture site near Ningbo has revealed a collection of silk-wrapped ivory rattles. These delicate instruments, found in the burials of high-status children and priestesses, are believed to have played a central role in the 'Sea-Spirit' lullaby festivals. These ancient rites involved communal singing and music intended to 'calm the tides' and ensure the safety of coastal villages during the monsoon season.
The rattles were carved from mammoth ivory and encased in multiple layers of primitive silk, some of the earliest examples of the textile ever found. Forensic sound analysis of the internal stone beads suggests they produced a soft, rhythmic sound mimicking the ebb and flow of waves. This find highlights the emotional and protective aspects of Neolithic festivals, where music was used as a tool for environmental propitiation and communal psychological comfort.
