Music Together^® was founded in 1987 by Kenneth K. Guilmartin in Princeton, New Jersey. In the 1980s, Ken was a working theatre composer and music educator who was drawn to the field of early childhood music education while working as an associate editor for his uncle’s music publishing business, Birch Tree Group. During this time, Ken observed that the music experiences of the children he knew and taught were usually limited to passive music listening; these children were growing up with little or no opportunity for live and playful music making. Subsequently, many sustained a delay in the development of their basic music skills, arriving at elementary school unable to sing in tune or move in a rhythmically accurate way.
