Uilleann pipes, Piobai uilleann (literally, pipes of the elbow ), from their method of inflation which is an elbow bellows The uilleann pipes have a different harmonic structure, sounding sweeter and quieter than many other bagpipes, such as the Great Irish War pipes, Great Highland Bagpipes or the Italian Zampognas. The uilleann pipes are often played indoors, and are almost always played sitting down. The bag of the uilleann pipes is inflated by means of a small set of bellows strapped around the waist and the right arm (in the case of a right-handed player; in the case of a left-handed player the location and orientation of all components are reversed). The bellows not only relieve the player from the effort needed to blow into a bag to maintain pressure, they also allow relatively dry air to power the reeds, reducing the adverse effects of moisture on tuning and longevity. Some pipers can converse or sing while playing.
