Arghoul

The arghul (Arabic: أرغول‎ or يرغول‎‎‎), also spelled argul, arghoul, arghool, argol, or yarghul (Israel), is a traditional Egyptian and Palestinian musical instrument. It has been used since Ancient Egyptian times and is still used as a traditional instrument in Egypt and Palestine.

Modern Arghul, 3 ft. 2½ in. long.

The arghul is a double-pipe, single-reed woodwind instrument that consists of two tubes: a melody pipe with between five and seven holes and a longer drone (Arabic ardiyya, "ground") pipe. Its tone is similar to that of a clarinet, although a bit more reed-like. Unlike the similar mijwiz, the arghul has only fingering holes on one of the instrument's pipes (the melody pipe), and the drone pipe has a detachable length that allows the player to alter the pitch of the drone.
