Bagpipes are a class of musical instrument, aerophones, using enclosed reeds fed from a constant reservoir of air in the form of a bag. Though the Scottish Great Highland Bagpipe and Irish uilleann pipes have the greatest international visibility, bagpipes of many different types come from different regions throughout Europe, Northern Africa, the Persian Gulf, and the Caucasus.
The term "bagpipe" is equally correct in the singular or plural, although in the English language, pipers most commonly talk of "the pipes", "a set of pipes" or "a stand of pipes".
Pakistan is one of the world's largest producers of bagpipes and is the second largest exporter after Scotland.
Since the 1960s, bagpipes have also made appearances in other forms of music, including rock, metal, jazz, hip-hop, punk, and classical music, for example with Paul McCartney's "Mull of Kintyre", AC/DC's "It's A Long Way To The Top", Korn's "Shoots and Ladders", John Farnham's "You're The Voice" and Peter Maxwell Davies's composition Orkney Wedding, With Sunrise.
