The bagpipe has three main parts: a blowpipe, a bag, and a chanter. The piper blows into the blowpipe, which fills the bag with air. The air then travels through the chanter (which is kind of like a recorder) to create the sound. The piper covers one or more finger-holes in the chanter in different combinations to create different notes. There's also usually at least one drone pipe that plays one constant note underneath the melody. Bagpipes are most often used to play traditional folk music. Although often thought of as Scottish, the bagpipes are used throughout the British Isles, Europe, the Middle East, and parts of Canada.
