While bagpipes are the national instrument of Scotland, they have existed across Europe, the Middle East, and North Africa for thousands of years. The basic design includes a blowpipe for air, a bag to act as a reservoir, a 'chanter' for playing the melody, and one or more 'drones' that provide a constant background note. The player squeezes the bag under their arm to maintain a steady flow of air through the reeds, allowing the music to be continuous without the player needing to blow constantly. Historically, the Great Highland Bagpipe was used as a 'weapon of war' to inspire Scottish troops and intimidate enemies on the battlefield. Today, they are staples of military bands, funerals, and Celtic folk music, known for their powerful volume and distinct, piercing timbre.
