Cong-Chieng, or gong, is a musical instrument made of alloy bronze, with an occasional additional composition of either gold, silver, or black bronze. In the Kinh language, the word “Cong” relates to convex gongs, while “Chieng” identifies with the flat ones.  

Gongs can be played one a time or in groups, consisting of 2-20 pieces of the instrument. When played as an ensemble, the gongs come in different sets, number, and function during the performance. They can be struck with either a wooden stick, mallet, or even bare hands.

Different ethnic groups use gongs in different ways and purposes. The Muong and other ethnic groups in the Truong Son-Tay Nguyen regions use gongs not only to beat the rhythm but also to play polyphonic music. In some ethnic groups, only men are allowed to play the gongs. On the other hand, the sac bua gongs can only be used by women in the Muong tribe. Other ethnic groups allow both men and women to play the gongs. How the instrument is used depends on each ethnic group’s customs and ethnicity.

Aside from its varying use and purpose, gongs also hold an important place in the lives of many ethnic groups in Tay Nguyen. In all important occasions, whether celebratory or sorrowful , gongs are always present. Almost every family has at least one set of gongs. Gongs are revered as sacred instruments, so you can always find them in joyous gatherings like New Year festivities, agricultural rites, wedding ceremonies, and victory celebrations, among others, as well as in unfortunate events like death and funerals. Gongs are an ever-present instrument in occasions such as offerings and rituals, and basically any significant gatherings in the community.

Gongs have a way of bringing life and meaning to any event, thus elevating its relevance to a spiritual level. And as such, The Space of Gong Culture in the Central Highlands of Vietnam earned the title of Masterpiece of the Intangible Heritage of Humanity by no less than UNESCO.
