The Royal Opera House was straightforward about their reason for dropping soprano Deborah Voigt from an upcoming production of “Ariadne on Naxos.” They wanted someone slimmer for the part. The casting director envisions Ariadne in an elegant, black evening gown, and also stated that it’s not just a question of how a soprano looks but “how they move on stage.” In the past Voigt told Opera magazine “Honey, if you can find someone who can sing over that orchestra and still wear that size 5 costume, more power to you!”
