I bought this book after reading the reviews in this web site. I found this book very useful. This book does not have much writing(by comparing other books). It tells you everything that you need to know about ballet positions and movements. Every ballet position and movement is well illustrated in this book. For each position, from 1st position to arabesque, this book tells you how you position it. This book also shows you correct and incorrect positions in black-and-white photos. Although the photos are shown in black-and-white, these photos' quilities are excellent, so you can clearly see what are the photos trying to tell you. For ballet movements, there are step-by-step photos to show you the correct movements. This book also contains two pages of 'Pronunciation Guide' to remind you how to pronunce some ballet terms, and 8 pages on 'Glossary of ballet terms' which is very useful as well. I have been learning ballet for nearly 20 years, this book is really useful and a nice book to read and has improved my ballet skills and technique. If you are a ballet lovers or just started ballet and in love with it, this will be a must-have reference book for you!
