Sung-Hyun Yun is a Korean composer.
He spent most of his childhood in his birthplace of Busan, South Korea. Yun had played the piano from an early age and had studied music composition throughout his youth – at the age of 20, he moved abroad to the United States where he had attended and graduated from The San Fransisco Conservatory of Music (B.M.), Yale School of Music (M.M.), and the Eastman School of Music (Ph.D).
His time at these institutes had been spent under the guidance of Joseph Schwantner, Samuel Adler, Jacob Druckman, and Martin Breznick. During this period, Yun had also been awarded the Francis Wicks Prize, the Yale University John Day Jackson Prize, and the Eastman School of Music Howard Hanson Prize.
Yun is also a winner of the Washington International Competition for Composers as well as the Deutsche Oper Berlin Chamber Music Competition.
Yun has also remained active in his home country of South Korea, composing for the likes of the Festival Ensemble of Seoul, the Hwaeum Chamber Ensemble, the Yonsei Sinfonietta, and the Korean National Choir. Yun is currently a professor of composition at the Yonsei University in Seoul, South Korea.
