Jazayeri's setar usually has a small bowl made of mulberry or blackberry wood. In some cases, they use walnut wood. But the handle is always made of walnut wood, on which 25 frets are used.
The sound is transmitted from the instrument wires to the setar bowl by a small stick called a vault. The vault is made of boxwood and directs the vibrations related to the wire through a thin plate into the bowl. As a result, the sounds come out of the holes on the screen again after being reflected and intensified several times. The length of the Setar bowl is 22 to 30, its width is 12 to 18 and the depth of the bowl is between 12 to 16 cm.
Master Jazayeri believes that those who play the instrument and play it attract more attention because they see the exact result of their work. Maybe it's because what they produce has an identity of its own, it has a sound, and the process is generally tangible to them. Sustainability is also important in increasing instrumental pleasure. Because in general, the issue of permanence in works of art is important. For example, a good solo can last 5 years, 10 years, a good ballad can last 20 to 50 years, but we see an instrument that lasts over 100 years.
