The Hesper Quartet is a Korean-American chamber ensemble that was formed as a student group at the Emerson String Quartet Institute of Stony Brook University in 2022, where they have been mentored by Philip Setzer, Eugene Drucker, Lawrence Dutton, Paul Watkins, David Finckel, Jennifer Frautschi, and Colin Carr.

Since its formation, the quartet maintains an energetic balance of performing works by Beethoven, Schumann, and Haydn, while performing works by living composers such as Joan Tower. Notable achievements include winning first prize at the Fanny Mendelssohn International Competition, the Servaas Competition, and the Ackerman Chamber Competition.

Its members–Sojeong Kim, Ye Jin Yoon, SoHui Yun ,Connor Kim–hold degrees from the Curtis Institute of Music, the Juilliard School, Yale University, Stony Brook University, and Seoul National University. “Hesper” means evening star, and like how each star in the night sky has its own story, the Hesper Quartet strives to tell the fascinating story of each work of music that they play.
