This charming set of books has been designed to provide a practical approach to the theory of music composition for children as young as age six. All three books successfully present rather sophisticated concepts in an age-appropriate, child-friendly way. Volume 1 introduces the concepts of patterns in composing and focuses on the techniques of repetition, sequence, and retrograde by working with short motives. Volume 2 introduces children to the techniques of inversion, rhythmic shift, and fragmentation. Volume 3 introduces augmentation, diminution, and question and answer. Also in Volume 3, children are introduced to cryptics as an entertaining way to produce a random motive.  Don't let these sophisticated concepts turn you away from this book! If you're committed to teaching composition, buy it - you and you're young students will love it.
