Query: Excellent Beginner Book

I am an adult beginner and I am using this book. So far it has been wonderful and easy to learn compared to some of the other bigger, complicated books that I bought at the same time. Luckily, I have a great teacher who helps me with technique- where the book lacks. But I guess all music books lack in that because they can't see what you are doing right or wrong.
