Choi Seung-hyun, also known as Shawn Choi, is a composer whose work spans film and other musical forms. He has contributed as a music director and composer to dozens of feature films across diverse genres.

 

He was one of the composers on Oldboy, and composed the original score for Sympathy for Lady Vengeance.​​ His credits also include the romantic action-comedy My Girlfriend Is an Agent, as well as thrillers such as Wide Awake, Children, Black House, and The Guard Post.

​

Choi began his career as a guitarist, developing his compositional voice through independent study and classical training. He later earned a Master’s degree in Film Scoring from New York University. He has taught at several universities and continues to focus on composition. He is the founder of PSALM Music, a film scoring production company, and also creates faith-based music.

​​

While his film credits are originally listed in Korean (최승현), they often appear as Choi Seung-hyun in translation, with his name presented in various Romanized forms across platforms. Internationally, he also uses the name Shawn Choi, with both names referring to the same composer.

 

The name 'Shawn' resembles the sound of his Korean given name and was given to him by Professor Ron Sadoff at New York University. It means “God is gracious.”
