Music Together has developed nine song collections, each characterized by its own graphic, color, and instrument. These collections each include a recording and songbook and are designed to be used one collection per semester. The material is not sequential, so a family may begin Music Together classes in any semester with any collection.

The music is pitched in just the right range for children's voices and includes songs, rhythmic chants, tonal and rhythm patterns, and instrumental play-alongs, all in a rich variety of tonalities and meters. Original songs and arrangements by the program co-authors make these collections especially unique. Outstanding instrumentalists play a variety of instruments such as guitar, bass, flutes, keyboards, and percussion.  All of the songs are suitable for mixed-age groups and perfect for childcare centers or families with children of different ages.

Music Together's song collections are research-based and artistically conceived and produced. They are also classroom and family tested. Since 1987, the feedback of hundreds of teachers and thousands of families has been incorporated into these constantly evolving materials.
