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 is equally correct in the singular or plural, although in the English language, pipers most commonly talk of "pipes." .
