Jin Oh is a Singaporean composer, sound designer, and guqin player that is based in Finland. As a musician of both Western and Traditional Chinese music background, his music explores both individually as well as the intersection of both across myriad ensembles ranging from choral to wind band to mixed ensembles, occasionally with electronics. His music has been broadcast on YLE Radio and was also performed by international ensembles such as the Keys Ensemble, Uusinta Ensemble, and the Zagros Ensemble. Aside from concert music, his music also intersects with dance such as with the dance theatre group, Ethno Contemporary Ballet.

His mentors in composition and electroacoustic composition include Veli-Matti Puumala (Finland), Tapio Tuomela (Finland), Sami Klemola (Finland), Alejandro Montes de Oca (Finland/Mexico), Josue Moreno (Spain/Finland), and Zechariah Goh Toh Chai (Singapore). He is also under the guidance of Hoh Chung Shih (Singapore) for guqin.
