The John Day Co. / ISBN 0381981940 (1972)
You realize the book isn't quite what you'd expected when you look at
the Table of Contents and, instead of a neat list of choreographers,
you see: "Part I - Choreography in Creation", followed by
"A Ballet Is Proposed," "The Beginning," "Choreographer and Company," etc.
This is actually more of a detailed explaination on how a ballet is born,
nurtured, matured, and finally presented. Of course there are many famous
names (Njinsky, Agnes deMille) and examples (Rite of Spring," "Rodeo")
but the concentration of the book is on the art and agony of choreography itself.
