A front view of traditional scottish band musicians singing with bagpipes and drums. Sound included. A set of bagpipes minimally consists of an air supply, a bag, a chanter, and, usually, at least one drone. Most bagpipes have more than one drone (and, sometimes, more than one chanter) in various combinations, held in place in stocks — sockets that fasten the various pipes to the bag. he most common method of supplying air to the bag is by blowing into a blowpipe, or blowstick. In some pipes the player must cover the tip of the blowpipe with his tongue while inhaling, but most blowpipes have a non-return valve that eliminates this need.
