There are two types of reed, single and double. The zurna or shawm class of instrument uses a double reed in a conical bore pipe, producing a loud, wild sound similar to the Scottish Highland pipes. The arghul class uses a single reed and produces a quieter, more mellow sound. Single reeded pipes are often played in unison pairs with parallel finger holes, for example the Egyptian mijwiz or zummara. The arghul is played in Egypt and the Levant, with either a short or long drone. The Turkish sipsi is a single reeded pipe played without a drone.

Technically the duduk is a reeded pipe, but because of its increasing popularity and profile it merits a page of its own on this site here.
