When playing, Giarai instrumentalist ties string ends on one side of the instrument around his belly while binding the other end of the strings to a branch of tree. He then would play the instrument by knocking on tubes with 2 short sticks. Milpas are always full of T'rung sounds as Giarai people play T'rung at their leisure time after tense working hours, and also for the purpose of driving away wild animals and birds. Today, T'rung has been introduced to professional performance.

Cong Pothi (No. 10): is a piece of gong music performed in Bo nha mo ceremony known as Pothi ceremony among Giarai people. Annually, when the dry season comes and the harvest finishes, Giarai people prepare materials to build a new sepulchre and hold a ceremony to mark the relatives' final caring of the dead's soul at his tomb after a certain period of death. Pothi is regarded as the greatest, longest and merriest event among festivals of Giarai people. Participating in the festival not only are gong orchestras of the host village, but also orchestras of neighboring villages. The sounds of gongs go far and wide mountains and forests, and animate the whole sepulchre area where quietness and desolation pervade all year long. Musical pieces of gong music in Pothi mainly imitate melodies of folk tunes.
