DAK NONG (VNS) — Local farmers found two lithophone sets on a pepper plantation in Long Son Commune in the Central Highlands province of Dak Nong yesterday.

A spokesman for the provincial Department of Culture, Sports and Tourism said that one of the sets had 10 stone pieces, while the other had seven.

The department has taken charge of the instruments for preservation and further study.

A set of lithophones, first found by the French in Dak Lak Province in 1949, is made up of 11 stone tablets.

Other instruments were later discovered in Khanh Hoa and Binh Phuoc.

Evidence of the lithophone dates back 10,000 years. — VNS
