Uilleann pipes

The uilleann pipes (/ˈɪlən/ or /ˈɪljən/; Irish: [ˈiːl̠ʲən̪ˠ]) are the characteristic national bagpipe of Ireland. Earlier known in English as "union pipes", their current name is a partial translation of the Irish-language term píobaí uilleann (literally, "pipes of the elbow"), from their method of inflation. There is no historical record of the name or use of the term 'uilleann pipes' before the twentieth century. It was an invention of Grattan Flood and the name stuck. People mistook the term 'union' to refer to the 1800 Act of Union; this is incorrect as Breandán Breathnach points out that a poem published in 1796 uses the term 'union'.

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.
