As the Primary children are already familiar with individual instrument timbre, musical selections with multiple instruments are introduced. Groupings of musical selections to represent different eras in music history, different composers can be offered to the Primary children. These selections are longer then those in the Infant Commuinity as the Primary child's attention span is greater then the children in the Infant Community.
