장구 is a traditional Korean percussion instrument, often used in folk music and dance. It consists of a barrel-shaped body made of wood, with two heads covered in animal skin. Players use a stick to strike one side while using their hand to hit the other, creating a unique sound that is both rhythmic and melodic. This instrument is commonly associated with various Korean cultural performances, including 판소리 and 농악. The 장구 plays a vital role in maintaining the tempo and enhancing the overall atmosphere of these events, making it an essential part of Korea's musical heritage.
