Bagpipes are a musical instrument most people associate with Scotland, although various forms of bagpipes have been played in lots of different countries. Someone who plays bagpipes is called a piper.

Bagpipes, as the name suggests, are made from an airtight bag with several pipes attached to it. The pipes are a chanter that you use to play tunes, and one or more drones that make a continuous noise. The piper keeps the bag full of air by blowing into it, and squeezes air out of it with their arm. You can't stop bagpipes from making noise while there is air in the bag.
