The 가야금 (gayageum) is a traditional Korean string instrument, known for its beautiful sound and unique design. It typically has 12 strings, although variations can have more. The instrument is made from wood, and its body is shaped like a long, flat board, which helps produce its resonant tones. Playing the 가야금 involves plucking the strings with the fingers or using a plectrum. It is often used in traditional Korean music, including genres like 국악 (gugak) and 판소리 (pansori). The instrument has a rich history and is an important part of Korea's cultural heritage.
