Percussion
Though Gangak is used as a relative word of Tang music in Tang Dynasty, it is not known that Tang Dynasty originated from Tang Dynasty music in today's Korean music. Aak is an ancient court music in China, and Dangak is the folk music of the contemporaries. It was different from the cheonggak of the food of the day, but it is changed into the food of the day. Today's sacred music comes in six-syllable, separated from the five-scale in that the pitch of the sperm is the next, and the pitch of the sperm is lower than that of the lower sperm. Instrumentation is not only organized in the form of a bass drum, but is mixed with a percussion instrument. Actually, it is only Baejaja and Luoyangchun that are passed on to the music, and the music influenced by Baejak is Yeongmulkhae, Baekjeong and Haejung.
