The skills of making a rabab instrument and its structure, a stringed instrument

The frame of this instrument is made of seedless mulberry wood like many traditional instruments. They hollow out the inside of the wood and cover it with goat skin. In ancient times, the thread was made from sheep intestines. But over time, some changes are made in the curtains, and the strings are made of nylon. Because nylon is more resistant and more economical than sheep intestine.

It should be noted that Rabab generally consists of four parts, namely, belly, chest, handle and head. The abdominal part is actually a hollow space in the shape of a melon, which has a thin but resistant skin on its surrounding wall. Also, a short fold is placed on the skin.

The chest in Rabab instrument is in the form of a triangular box. The peripheral surface of this box is made somewhat round to take a fish shape. This box is also made of wood. In the side walls of the chest, there is an element called Haft Gushi. Amplifier wires are wrapped around seven earphones. The chest is up when playing.

There is a window on the other side surface, the lower surface. The shape of this window is circular and the handle is almost short. About ten "hands" are installed on the handle.

In the head of the device, the phones are placed, and in the upper and lower parts of the box, there are three phones each. The side surface of the phone case continues somewhat towards the back.

On the other hand, the number of strings of Rabab is six or three strings are tied in pairs. Paired strings are tuned with each other. The bass wire in the Rabab instrument has a metal coating on its nylon body. Therefore, in short, it can be said that the components of the rabab include the bowl, body, plate, handle, ears, shaitanak, wire grip, claw head or crown, skin, vault, hands, muzrab, main strings one, two and three in the form Thin gut, string number four is thick gut and steel strings (steel).
