An extensive book on basic technique and terminology. Following a preface by George Balanchins, Kirstein's essay on the historical development of ballet is a conveniently nut-shelled introduction to Carlus Dyer's positional drawings, the main bulk of the book, for which descriptive texts have been written by Muriel Stuart. Exercises at the bar, exercises in the center, allegro and dance on pointes are the four parts under the basic technique and terminology heading and within the parts there is complete description of the steps, movements and sequences involved. The illustrations, ink drawings necessarily graphic to show body and muscle positions, are standard but good. The introduction despite its completeness is short, making this a book that will primarily interest the person who wants to know more about ballet technique.
