Teaching children the language of music.




The Children's Orchestra Society, founded in 1962 by Dr. H.T. Ma, is a not-for-profit organization dedicated to "teaching the language of music" to children and teens. Our mission is to cultivate and nurture children and teach them teamwork and life skills through music-learning and performing in orchestral and chamber music settings. Members of COS receive excellent training in classical music and opportunities to perform in concerts with their peers as well as with well-established musicians.



A child's innate capability to learn and develop musical talent of the highest level, when nurtured in a cooperative environment: 

This is the core belief of Director Dr. Yeou-Cheng Ma and Music Director Michael Dadap, who have led the Children's Orchestra Society since 1984. In an interview with Causes, Dr. Ma explains, "We have expanded on the 'tailor-made' parts my father used to write so that each child could take part in the group experience, despite differing levels of competence."



Success for COS means instilling each young musician with the invaluable experience and individual benefits of music making.

To reach this goal the faculty works hard to:

  • Foster a supportive learning environment;
  • Create opportunities to perform;
  • Provide role models and a bridge to the professional world through master classes and performance collaborations with eminent musicians;
  • Enrich and involve the community through performances for civic and cultural groups.

Please listen to this delightful interview with Dr. Ma to learn more about who we are and what we do.

COS was my very first orchestral experience, clearly one that has touched my life in immeasurable ways. I know that I would not be doing what I am doing now were it not for those incredible years of fun music-making.
