Answer:
Percussion instrument and idiophone
Step-by-step explanation:
Kongvong, also called kong vong toch, is an instrument made of a variety of gongs places on circle-shaped racks.
Kongvong belongs to the percussion family of instruments, meaning the sound is made by striking a surface, either by hand, beater, or another instrument.
The sub-classification of kongvong is that it belongs to the idiophone group of instruments when separated by the method of sound production. Idiophone instruments make the sounds with the vibration of the whole body of the instrument.
