Name: Arghul - a double reed instrument from North Africa with two asymmetrical pipes. One pipe, the chanter, is dedicated to the melody and usually has 5 or 6 finger-holes. The second pipe, the drone, is much longer and produces a single note. The instrument is played inside the player's mouth using circular breathing. Both pipes are made from reed or other similar materials and are attached together with strings, wax, tar or glue.
