The first historical noting of "aak" was during the Unified Silla period of "668–935", however this is only due to the existence of "aak" instruments, and no music or performance coexisted at this time. "Aak" music and performance to began to spread across Korea for the first time during the Goryeo Dynasty of 918–1392. "Aak" was first introduced to Korea during "1116", when the Chinese emperor of the Sung Dynasty first presented the Korean court with "aak" instruments and court dance instructions; Emperor Hyejong of Goryeo provided Emperor Huizong of Song with a gift of 428 music instruments, 572 costumes, and ritual dance objects imported from China. This created the growth in popularity for "aak" within Korea, however the genre saw an eventual decline afterwards. The Yi Dynasty during "1392-1910" then allowed for a completely finalised version of the "aak" system to rise across Korea, as the year "1430" saw the revival of the genre through a more modern reconstruction of traditional "aak" melodies.
