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

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 fingering holes on only 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.

In the illustration above all three lengths are shown in use. An arghul belonging to the collection of the Conservatoire Royal at Brussels, described by Victor Mahillon in his catalogue (No. 113), gives the following scale: —

Arghuls are used in Egypt, Palestine and other Arab nations as an accompaniment to belly dancing, Dabke, and other types of Arabic musical performances. Circular breathing is an important part of the playing of the instrument.

There are three varieties of arghuls: the small arghul (arghoul alasghar), the medium arghul (arghoul alsoghayr), and the large arghul (arghoul alkebir).

Çifte is a Turkish folk instrument of the wind type. It is made by tying two reed pipes side by side. Two small reed pieces which produce the sound are added to the ends of both reeds. These two small reeds are taken into the mouth cavity and it is played by blowing the air into both at the same time.

There are two çifte types known as Demli Çifte and Demsiz Çifte. In demli çifte one of the reeds does not have any pitch keys and it just produces a drone. There are melody keys on the other reed and the main melody is played through them.
