Kenneth K. Guilmartin was a theatre composer and music educator in the 1980s when he founded Music Together in Princeton, New Jersey. He was inspired to bring live and playful music making experiences to children, as he noticed that they were often limited to passive music listening. After nine collections of parent-child songs and additional curriculums were developed, the Music Together program was offered in over 40 countries. It provides the benefits and joys of music making to families through its parent-child, preschool, and outreach programs. Ken and Lili continue to teach Music Together classes and train others to do the same.
