In almost every age the world of dance has produced its own pioneers - leading dancers and choreographers who have experimented with new styles and new forms. Margot Fonteyn looks at the work of some of the greatest of the pioneers, from the Commedia dell'Arte in 17th-century Italy to Martha Graham in 20th century America. The programme includes a performance by Fonteyn and Baryshnikov of Fokine's famous ballet, Le Spectre de la Rose.
