Brittany During the First World War, some Breton pipers serving in the French Army came in contact with the pipers of Scottish regiments, and brought back home a few Great Highland Bagpipes which Breton pipe-makers started copying. Polig Monjarret led the introduction of the Great Highland bagpipe to Brittany during the Celtic revival of the 1920s Breton folk music scene, inventing the bagad, a pipe band incorporating a binioù braz section, a bombarde section, a drums section, and in recent years almost any added grouping of wind instruments such as the saxophones, and brass instruments such as the trumpet and trombone. Well known bagadoù include Bagad Kemper, Kevrenn Alre, Bagad Brieg and Bagad Cap Caval. In Brittany, the Great Highland bagpipe is known as the binioù braz, in contrast to the binioù kozh, the small traditional Breton bagpipe. One notable development of the Highland bagpipe in Brittany is the creation of slightly shorter drones in C (Scottish "B"; see notes on tuning above), so that the many tunes played in that key will have drone accompaniment in the tonic. Many bagad pipers will keep two sets of pipes, one in standard B (Scottish "A") and one in C, and a whole suite may be performed in C. Notable bands Some of the most famous pipe bands in the world are the Shotts and Dykehead Caledonia Pipe Band, Simon Fraser University Pipe Band (SFUPB), The Inveraray & District Pipe Band, The Field Marshal Montgomery Pipe Band and the St. Laurence O'Toole Pipe Band, all of which have won the World Pipe Band Championships. Related instruments Practice chanter, a bagless and droneless double-reeded pipe with the same fingerings as the Great Highland bagpipe. These are meant to serve as practice instruments which are more portable and less expensive than a set of pipes. Practice goose, a small, single-chanter, droneless bag used to transition between the practice chanter and full pipes Reel pipes (or "kitchen" or "parlour" pipes), smaller versions of the Great Highland bagpipe for indoor playing Border pipes are similar to the Great Highland bagpipe, but quieter and thus suited to playing for dances and sessions. Rather than being inflated by mouth, their air is provided by bellows under the arm. Scottish smallpipes are a modern interpretation of extinct smaller Scottish pipes used for recreational music. They
