A set of stone musical instrument dating from 3,000 years ago has been handed over to the museum of the southern province of Binh Thuan.

The music instrument comprises of five slabs of black blue stone, which when arranged from small to big form a trapezoid. This is a typical character of ancient lithophone, different from new lithophones or sounding stone slabs.

The lithophone was unearthed by a farmer in Da Kai commune, Duc Linh district, when he dug holes for planting coffee trees.

Earlier, the Binh Thuan museum in coordination with a Japanese expert also discovered another lithophone at a site only 3km away from the place where the 3,000-year-old one was found.
