Query: Excellent - Easy referencing

I purchased this book about a week ago and have found that it covers a large amount of information in one book. It is an excellent reference guide, or would be great for someone having little understanding of theory to learn very easily the basis of music theory. The exercises at the end of each chapter help to touch on the high points, and the appendix has a great chord reference. The visual aids (tips, notes, definitions,...) are also great for filling in some of the knowledge gaps. The CD is also great to use while going through the chapters.
