Music played an important multifaceted role in individual development. It served as a valuable non-verbal communication tool for those who might otherwise be locked in silence. Music could also help to spur activity, evoke inner emotions and bring satisfaction. The study explored the efficiency of music therapy for the development of a group of autistic children. The curriculum included music appreciation, singing, movement, improvisation play, music storytelling and playing instruments. The activities helped to promote learning motivation; enhance cognition, language expression, self-concept, movement development, learning interest and participation; improve concentration and expand social interaction. In crucial areas where development in this group is low-social adaptation, communication ability and self-expression-the children received benefits by participating in music.
