Korean classical performance refers to the traditional music of Korea, which dates back to the Three Kingdoms period (57 BC – AD 668). It includes various forms of vocal and instrumental music, such as court music, folk music, and religious music. Korean classical performance is characterized by its use of unique instruments, such as the gayageum (a zither-like instrument), the haegeum (a two-stringed fiddle), and the daegeum (a bamboo flute). It is often performed at cultural events and ceremonies, and is considered an important part of Korean heritage.
