This is a great way for students to get into writing their own music. I reviewed what amazon had for sale and what Sam Ash had. You get more for less buying from San Ash. I am glad that I read the descriptions and informative about the products before I purchased. You definitely get more from Sam Ash. My child has told me that the book is the better than others in the class. Look carefully at what you are buying. Some are small and not what your child needs.
