Soprano Deborah Voigt’s sacking by Covent Garden because she was too big for the costume designed for the production is an example of misplaced priorities. “Voigt’s case is exceptional: it’s hard to think of another singer who was dumped for not having the right looks. What is noticeable is that European companies are giving stage directors an increasingly active role in casting. In some cases, it’s the only way to attract a top-flight director. Visual realism is becoming as important as the right voice type.”
