This is a wonderful addition to the literature on ballet. The auther makes her apologies in the beginning for not being able to include some noteworthiy teachers, but the ones she was able to cover are great. The information provided gives us valuable insight into the aesthetic principles of these great dancers and teachers. This should be useful to all dancers, whether they teach or not. Some very esoteric facts can be found here as well, such as why Balanchine likes the fingers and hands held the way he does and why many don't like it that way. I had taken some classes with a Mr. Schabel and discovered his claim to fame in these pages. The Great Jean Babilee is even discused. You might also get some good ideas for further reading in this book as I did.
