Shells found in Spain could be among oldest known musical instruments

Researchers in Spain are studying 12 large shell trumpets discovered in Neolithic settlements and mines in Catalonia, dating back to between the late fifth and early fourth millennia BC. Led by Miquel López García and Margarita Díaz-Andreu from the University of Barcelona, the team believes these shells, found in north-east Spain, may be among the oldest known musical instruments. The shells, identified as Charonia lampas sea snails, appear to have been collected for non-culinary purposes, with their tips removed to function as trumpets. Acoustic experiments conducted on eight intact shells produced stable tones, similar to a french horn, suggesting their use for long-distance communication and musical expression. Researchers are exploring the shells' musical potential, noting the ability to shape the tone and notes through improvisation.
