What creates truth onstage?
Seriousness. Taking the words and the music seriously. Not mocking yourself, not interpreting it. No irony. As I said about Klytämnestra: Believe her! Be it! Don’t make a comment on it. I did several productions with the director Klaus Michael Grüber, who told me to imagine the whole audience was 11 years old. An 11-year-old knows already everything about love, hate, hope, betrayal, all those feelings, but he doesn’t like irony and sarcasm.
Are there roles you considered singing that you didn’t, and regret?
No. There were two occasions when I had signed contracts and then decided not to, and it was the right choice. I had a signed contract to do Brünnhilde in “Die Walküre” at La Scala. Daniel Barenboim thought I could have conveyed new things in the role, and I agreed, but couldn’t figure out how to sing it.
I also had a contract for Salome at the Deutsche Oper in Berlin, when Götz Friedrich was the intendant [artistic director], conducted by Giuseppe Sinopoli. But looking at the music, I thought, No, I am not Salome. To sing it — that’s soprano soprano. You have to have a silver voice. I’m copper. Of course, you don’t hear those silvery Strauss voices as much now.
Did you ever wish you could sing something for a different voice type — a tenor, or a baritone?
The Ingemisco in the Verdi Requiem! And seriously, in “Don Carlo,” Philip’s aria from the fourth act, “Ella giammai m’amò.” But, you know, if you have the chance to listen to it when it’s sung by someone that is touching you deep down in your soul, then it’s better you have not sung it yourself.
What are your reflections on your years singing at the Metropolitan Opera?
Well, let’s not talk about the “Carmen”! I always loved the Met. I always felt I had the support of people there. Joe Volpe was the best intendant ever. “Only a happy singer is a good singer,” he said. He made us feel comfortable, feel good showing our best.
It’s a big house. It’s different to sing there. You have to act bigger, sing with more sound. Real theater-making is maybe not the thing you should ask for at the Met. A subtle gesture like I might make at the house here in Berlin will maybe be perceived up to Row 10, and then be lost.
