The Vietnamese Lithophone is a set of stone slabs of different sizes and shapes fabricated through an elementary technique. These stones are available in the mountainous areas south of Central Vietnam and east of South Vietnam. Discovered by Georges Condominas - a French, in Dak Lak in 1949, Lithophone is an ancient musical instrument with 11 slabs of stone.[caption id="attachment_10768" align="aligncenter" width="640"] The Vietnamese Lithophone is a set of stone slabs of different sizes and shapes fabricated through an elementary technique.[/caption]
Later, four more Lithophone were discovered in Song Be and Khanh Hoa. It results from the researches that Lithophone existed between 4,000 and 10,000 years ago. At the end of the 1980s, 200 stone lithophone slabs had been discovered in Dak Lak, Khanh Hoa, Dong Nai, Ninh Thuan, Binh Phuoc, Lam Dong, and Phu Yen Provinces. Each set is comprised of between three and 15 bars. The the oldest extant set, first discovered at Ndut Lieng Krak in Dak Lak Province in 1949, is now kept in a French museum. Most of the other sets are exhibited throughout Vietnam. They were quarried from a place nearby where the rock is made of petrified wood and were chipped and shaped to tune them to a perfect pentatonic scale. They can still be played, by hitting them with wooden mallets, to make a sort of hugely antique stone marimba.
For some ethnic groups in Tay Nguyen or Central highland, the stone slabs are sacred and preserved as family treasures played during grand ceremonies for the gods. For others, the stone slabs are used for setting up crop-protection devices.
