The janggu is a traditional Korean drum that has a unique hourglass shape. It is made from wood and covered with animal skin on both ends, producing a rich and resonant sound. The janggu is an essential instrument in various Korean music genres, including pansori and samulnori, and is often played during festivals and celebrations. Musicians use two sticks to play the janggu, striking different sides to create contrasting tones. This versatility allows it to accompany singing and dancing, making it a vital part of Korean cultural performances. The janggu not only adds rhythm but also enhances the overall atmosphere of traditional events.
