Born in Korea, Christine (Yun Seo) Sul was introduced to music at a young age, as her mother was a piano instructor who ran her own music academy and also conducted choirs. She began piano studies at six and later trained formally with Prof. Taehui Park until completing her first year at the prestigious Busan Arts High School. She then moved to Canada, seeking new experiences and perspectives that would enrich both her life and her studies. There, she had the privilege of studying under Prof. Marilyn Engle at the University of Calgary, where she earned her Bachelor of Music in Performance.

Christine has received numerous accolades in Korea, including Grand prizes at the Busan Joongang and Changwon International Meister Piano Competitions. In 2008, she made her orchestral debut performing Mozart’s Piano Concerto No. 21 in C Major, K. 467 with the Soloists of Volgograd Orchestra. During her university years, she was recognized for her distinctive musical voice and interpretive depth, earning multiple scholarships. In 2021, she was named the Prairies Favourite in the 19–25 division of the Canadian Music Competition, and in 2023 she performed with the Calgary Philharmonic Orchestra as an RBC Concerto Competition winner.

She has been a regular participant in international festivals in Portugal, including the 2018 and 2020 editions of the Coimbra World Piano Meeting and the Sardoal International Piano Meeting. Her performances in 2018 drew enthusiastic local audiences, many of whom returned to hear her again in 2020. At these festivals she also took part in masterclasses with renowned professors such as Aquiles Delle Vigne, Makoto Ueno, and Niklas Pokki.

In addition to her solo career, Christine is an active chamber musician and accompanist. She performs regularly as a collaborative artist in the Amici String Program and has appeared in various ensemble settings across Canada.

Christine is currently a faculty member at the Mount Royal University Conservatory and also runs her own piano studio. As a teacher, Christine combines her diverse training from Korea, Canada, and Europe to guide her students toward both expressive artistry and solid technical foundations. She believes that with dedication and trust in her guidance, every student can achieve meaningful growth. Her teaching goes beyond exam preparation, encouraging students to discover the deeper beauty and true value of music and to connect it with their lives. Under her mentorship, students have completed RCM examinations up to Level 10 and ARCT, with many earning First Class Honours with Distinction and being named to the RCM Honour Roll. For Christine, ARCT is not an endpoint but an important milestone - she continues to lead her students toward greater artistic maturity and a profound understanding of music beyond the framework of exams.
