Director of the Dong Nai Museum Tran Quang Toai said that the discovered instrument has five stone resonant slabs with the biggest slab being 75-cm long and 15-cm wide, and the smallest, 45-cm long and 10-cm wide.

Ethnomusicologists, however, are still unable to identify whether the instrument was made of local stone or not.
According to the provincial museum, the newly-discovered dan da has the similar material and shape with the one, found in Binh Da Ward, Bien Hoa City, which is dated back 3080 years ago.

The findings of the dan da will help prove the ancient Vietnamese people’s musical and art demand, said experts.
