This kind of instrument is modified from waste into a wooden instrument; the drum of the drum or the guitar string is installed in the wooden drum to make resonance, which produces a sound similar to the drum, some more advanced wooden boxes. The drum also includes a strainer, a resonance box piston pedal, and other percussion instruments.
The drum has five faces and the sounds are different. There is a circular hole for sounding on the back of the drum. Some of the modern drums are equipped with steel wires (small drums or guitar strings) to make the sound more characteristic.
