Welcome to the

Art of Four

Chamber Music Program

Art of Four is a new string quartet program based in the Greater Toronto Area, offering immersive, ensemble-based training for all musicians. Founded by Joanne Yesol Choi in collaboration with Noa Sarid of the award-winning Dior Quartet, Art of Four merges conservatory-level instruction with a fresh, youth-driven approach to learn the craft.

We are creating a space where high-achieving young musicians, beginners, and even adult amateurs can experience the joy, discipline, and deep collaborative spirit of chamber music — all within a professional but welcoming environment.

Our Mission

To foster chamber music excellence through hands-on quartet training that empowers young musicians to grow artistically, collaborate deeply, and build confidence — all in a high-level yet relatable setting. We aim to share the joy, discipline, and love in the art of string quartet playing.
