All of my beginning dressage students have this book on their shelves as part of my required reading. I chose it because it is a good basic overall for the novice rider. Moira Harris explains everything you need to know in an easy to understand manner. Many dressage books are too much for a beginner and may in fact frustrate instead of educate. DRESSAGE BY THE LETTERS is the perfect way to get your feet wet. But understand that is not intended to help you learn to train your horse, it is intended to help you start out in the sport of Dressage.
