Mijwiz is a type of musical instrument that sounds like a loud whistle. It is made of two pipes that are put together with a piece of leather in the middle. The musician blows into one of the pipes, which makes the air go through the leather and into the other pipe. This creates a sound that is very loud and can be heard over long distances. Mijwiz is often used in traditional music of the Middle East and North Africa, and sometimes it is played at celebrations like weddings or festivals. Imagine blowing on a whistle loudly with two parts that stick together, to make really cool music!
