Hurray for Music Play! I purchased this program at the recommendation of a colleague who used it when earning a doctorate in early childhood music education. It is a great program, but It is not laid out in an easy to understand manner and took me awhile to figure it out. It is less prescriptive than a program like Kindermusic, with the music teacher responding to the children as she directs a session, rather than a set program with a set choreography. The accompanying CD tracks are in an order different than in the book, which organizes selections by category: songs without words, with words, chants without words, with words. The songs represent a variety of meter, rhythms, keys, and modes. Accompanying activities are suggested for various stages of learning, most with simple, accessible props (like scarves or rhythm sticks). I have used it personally with my own children and in informal classes with other children and have discovered that they enjoy the program.
