Irish union pipe

The uilleann pipes are a type of Irish bagpipe. The name "uilleann" comes from the Irish word for elbow, as the instrument is played using bellows that are worked by the elbow.1

Unlike other bagpipes that are inflated by mouth, the uilleann pipes use bellows to supply air to the reeds. This instrument features a chanter for playing melodies and drones that produce continuous notes. A unique aspect of the uilleann pipes is the presence of regulators, which are accompanying pipes that allow the player to sound simple chords. This gives the uilleann pipes a melodic range of two octaves.12
