The đàn đá is a lithophone played by ethnic minority groups in the Central Highlands of Vietnam, in the provinces of Lâm Đồng, Đắk Nông, Đắk Lắk, Gia Lai, and Kon Tum.
These provinces are also home of the space of Gong culture listed in UNESCO's World Heritage Site.
The stone music sounds like the rhythm of the streams and bird songs, and therefore goes well with the surrounding landscape.
One of the oldest stone musical instruments ever discovered was found in this area, dating back more than 2,000 years ago.
