Combine joyful music with a brief story about what children of a tender age love to do, add a means to join in the performance, and you have the makings for fun for all involved. Here's a cleverly illustrated book for 3-4 year olds, that invites interaction through singing and accompaniment with a triangle, rhythm sticks, or whatever is available. One of the first truly interactive children's books is the work of Harmon S. Graves and illustrator Scot Ritchie: text and music by Mr. Graves, performed by the "TrebleMakers," a regionally recognized children's choir, with illustrations by Mr. Ritchie that capture the fun in which youngsters of this age group so joyfully engage.
