Born in Korea, Jiyoung Ko is a composer of orchestral, chamber, and vocal music whose works are deeply rooted in narrative, guiding her creative decisions. Her music often reflects themes of people, landscapes, and experiences, with an affinity for dense textures, resonant hues, and poetic, delicate melodies that shines through in all her creations. Her compositions encompass a wide range of styles—from cutting edge to traditional—that resonate with both ordinary and professional listeners. She seamlessly bridges the realms of intellectual depth and accessibility, an achievement frequently noted by audiences. One of her pieces was described as a 'brilliant study in timbre, tone, and color…a haunting piece.' (AB Newswire)

Her work has been performed in the United States, South Korea, Japan, and Germany by various ensembles, orchestras and musicians, including the Grand Rapids Symphony, Mivos Quartet, Dal Niente, WasteLAnd, Del Sol String Quartet, Cepromusic ensemble, Palimpsest, New York New Music Ensemble, Contemporary Music Ensemble Korea, NEC Honors Ensemble, KNUA Chamber Ensemble, Min Kwon, Christopher Adler, and Dan Lippel, among others.

In addition, her piece boiling/blooming will be performed at the HEAR NOW Music Festival 2025 on March 30th.
