Dangak (Korean: 당악) is a genre of traditional Korean court music. The name means "Tang music", and the style was first adapted from Tang Dynasty Chinese music during the Unified Silla period in the late first millennium. It was continued through the Goryeo (918–1392) and Joseon (1392–1910) dynasties, when, along with hyangak and aak it was one of the three approved genres of court music. Dangak performances were accompanied by Tang-style dances known as dangak jeongjae.
Together with hyangak, during the Joseon Dynasty dangak performances were the charge of the Jeonakseo (전악서; 典樂署; 1394–1457) and later of the Jangagwon (장악원; 掌樂院), the court office of music. Performers of hyangak and dangak were drawn from the lower classes, in contrast to performers of aak.
