Here is a quote by Reid Anderson, director of the Stuttgart Ballet Company on the importance of ballet schools to companies. The link is http://www.acts.hdm-...de/reviews.html
"I fear that both ballet schools and ballet companies tend to be the first target for cuts. So you’re always aware that the future of dance could be a bit gloomy. Stuttgart is a positive exception. People here have made ballet part of their lives. But elsewhere, few people realize what happens when you start cutting. One key example is cutting subsidies to ballet schools. When you do this, you remove a vital support from the local ballet company. Large casts draw upon a pool of dancers from the school. One third of my dancers come from the John Cranko School. A company of sixty dancers plus a local school can do almost anything. Without the back-up of students from the school a company loses flexibility and has to concentrate on small shows."
Wouldn't Stuttgart qualify for the top ten? I haven't personally seen the company in performance, but they have a school turning out excellent dancers, they have a "style" and a distinctive repertoire. Is their corps de ballet standard or some other factor keeping them out of the top ten, or is it just lack of travelling/exposure?
