ار Three -stranded bowl
Resonating bowl is one of the components of three strings, which is a pear-shaped bowl made of wood, and there is a wooden plate on its mouth. The three-stringed bowl is made both in one piece and from joined cracks of wood, and for the sake of beauty, designs with shells or bones are sometimes installed on it. The three-stringed bowl is structurally similar to the oud or tanbur bowl, but smaller than them and usually made of mulberry wood.
