The 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 Viet Nam and east of South Viet Nam.  Examination of the stone slabs found at Binh Da archaeological site in Dong Nai Province has revealed that this instrument may have existed for over 3,000 years. At the end of the 1980s, 200 lithophone stone 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 first set, 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 Viet Nam.

In the Kinh language, the word cong identifies convex gongs and the word chieng refers to the flat ones. Gongs vary in size from 20 to 120cm in diameter. Gongs may be played one at a time or in groups of 2 to 20 units.

T'rung is one of the popular musical instruments closely associated with the spiritual life of the Ba Na, Xo Dang, Gia Rai, E De and other ethnic minority people in the Central Highlands of Viet Nam.  It is made of very short bamboo tubes differing in size, with a notch at one end and a beveled edge at the other. The long big tubes give off low-pitched tones while the short small ones produce high-pitched tones. The tubes are arranged lengthwise horizontally and attached together by two strings. There are three types of T'rung: high, medium and low tones. The simplest type is composed of five tubes corresponding to La, Do 1, Re 1, Fa 1, Sol 1 and producing deep and resounding tones.
