ONE Chamber Choir was founded in 2009 by Lim Ai Hooi, and comprises choral enthusiasts with rich choral performing experience.
At ONE Chamber Choir, we believe in the transformative power of choral music to touch hearts and bring communities together. Established in June 2009 as a young adult choir under the baton of Ms Lim Ai Hooi, the choir's mission is to challenge the norms of conventional choral delivery, bringing a new dimension to choral music.
On the international stage, the choir has clinched various awards over the years, including Champion of the World Choir Games in the Mixed Chamber Choir category. It has also brought renowned overseas clinicians to Singapore, such as Maestro Werner Pfaff from Germany, Maestro Māris Sirmais from Latvia, and Maestro André van der Merwe from South Africa.
For ONE Chamber Choir, singing goes beyond a performance — it is a means of honouring shared humanity, creating meaningful experiences, and fostering deep connections between both singers and the audience.
