A pipe and drum corps is a musical ensemble that primarily features two types of instruments: bagpipes and drums. The bagpipes produce a distinctive sound through a combination of a reed and a bag, while the drums provide rhythm and support. These groups often perform at parades, military ceremonies, and cultural events, showcasing traditional music and marching techniques. The corps typically consists of pipers, who play the bagpipes, and drummers, who may use various types of drums, such as snare drums and bass drums. Together, they create a powerful and engaging performance that highlights the rich heritage of Scottish and Irish music.
