The Joseon Literati Purges: From Muo to Gimyo Sahwa

Dive into the legacy of King Sejong’s music and arts – Aak and Jongmyo Jeryeak. Discover how royal ritual music shaped Korea’s cultural heritage and UNESCO honors today.
King Sejong the Great was not only a genius statesman but also a deep lover and innovator of music and the arts. His reign (1418–1450) witnessed the blossoming of Korean court music, the invention of new instruments, and the creation of works that still resonate today. What do you think about the connection between leadership and the arts? Do you feel inspired by leaders who champion creativity?
King Sejong cherished music and poetry, composing works like “Yongbieocheonga,” “Worin Cheongang Jigok,” and “Yominrak,” the last meaning “A Joy to Share with the People.” He worked closely with talented musicians, including Bak Yeon, and believed music could strengthen the nation’s soul.
Innovative at heart, Sejong reformed court music with Korean identity. During his reign, new musical instruments like the pyeongyeong (stone chimes) and pyeonjong (bronze bells) were invented or perfected, expanding the range of ceremonial music. Importantly, Sejong and his scholars developed the first Korean notation system (jeongganbo), allowing music to be preserved with unique precision.
Aak (meaning “elegant music”) refers to the Confucian ritual music played at state ceremonies. King Sejong revived and reconstructed Aak, infusing it with Korean spirit and royal dignity. Have you ever experienced traditional music at cultural rituals? What role did it play for you?
Aak originated as imported music from China centuries before Sejong. Recognizing its spiritual power, King Sejong led a major revival, reconstructing its melodies and adapting foreign elements to Korean tastes for ancestral rites. He reduced enormous Chinese-style orchestras to manageable ensembles, giving the music a distinctly Korean flair.
Aak uses instruments like the pyeongyeong, pyeonjong, chuk (wood block), bak (clapper), and more, creating a solemn atmosphere. Traditionally, Aak pieces are slow, stately, and performed by seated musicians, accompanied by precise dances expressing scholarly and military virtues.
Jongmyo Jeryeak is the ritual music performed during the royal ancestral rites at Seoul’s Jongmyo Shrine, honoring the kings and queens of Joseon. It is a masterpiece of Korea’s intangible cultural heritage, inscribed by UNESCO in 2001. Has this information been helpful so far? Would you like to witness Jongmyo Jeryeak yourself?
Jongmyo Jerye, the royal ancestral rite, honors Joseon's ancestors in ceremonies meant to ensure the well-being and legitimacy of the kingdom. The associated music—Jeryeak—was revamped under King Sejong and his successors, especially King Sejo. Two grand suites, Botaepyeong and Jeongdaeeop, form the musical core, accompanied by solemn dances (ilmu) symbolizing both scholarly wisdom and military success.
Today, Jongmyo Jeryeak is performed each year at the Jongmyo Shrine. The rituals gather musicians, dancers, and descendants of the Joseon dynasty, joined by the public and UNESCO observers. The music serves as a living connection to Korea’s royal past and showcases the enduring vitality of King Sejong’s vision for the arts.
