KIM Jeong-seung plays daegeum for both traditional and modern music. KIM is a performer of the Traditional Music Troupe in the National Center for Korean Traditional Performing Arts, the youngest member in Jeongnong ensemble and a member of Contemporary Music Ensemble Korea. While actively involved in the preservation of traditional daegeum music, KIM is also recognized as a forerunner of new Korean music. He is known as the first musician to incorporate ‘Multiphonics’ and ‘Circular breathing’ into daegeum performances. KIM has been invited to many international music festivals, such as Berlin Contemporary Music Festival, Pacific Rim Music Festival, and Asian Composers’ League Music Festival as a soloist. His interest in newly composed Korean music led him to engage himself in graduate studies; KIM received M.A with a thesis on daegeum techniques. KIM’s research explores innovative ways to extend daegeum’s role in traditional music, and provides guidance for daegeum musicians to approach contemporary Korean and Western music.
