SPIEGEL: Mr. Quasthoff, you have announced your departure from the music business. Was it because of your voice or your body?
Quasthoff: It was two things. I lost my brother Michael a year and a half ago. He was my best friend and confidant. He died of lung cancer at 52, and it was a huge loss. Then I become very ill with laryngitis and an inflammation of the vocal chords. I had always told myself that I would continue working if I got well and was able to function at the same level technically as I had before. But that wasn't the case.
SPIEGEL: You were at the peak of your career.
Quasthoff: I achieved everything one can achieve as a concert singer. Six Echo Klassik (German classic music) awards and three Grammys, and I also have my professorship at the Hanns Eisler Academy of Music in Berlin. Now I'm going to turn to other things, like readings or audiobooks.
SPIEGEL: Are you experiencing withdrawal?
Quasthoff: Not at all. I haven't regretted my decision for a second.
SPIEGEL: When you started singing, did it take long for your audiences to pay attention to your art rather than your body?
Quasthoff: Not long. My brother once said that I must have been born on the stage. You reach your audience at the moment when you really have something to say -- that is, when you're not just delivering a performance. Beyond that, there is a level that can't be learned. (The late German soprano) Anneliese Rothenberger once called it the "tears in the sound." I think I had that. Perhaps it isn't innate, and perhaps there's an existential connection to my disability. I performed cabaret at a very young age, which helps you connect with the audience quickly.
SPIEGEL: When was that?
Quasthoff: It was while I was studying law. And I can tell you this: You can still stick me in front of people for two hours today and I will entertain them, I will manage to do that.
SPIEGEL: Your recitals were emotional experiences for the audience.
Quasthoff: There are differences between the singers I call "voice owners," and the people who stand up there and do something that audiences are willing to buy as a performance. Although I do have to say that it's still very easy to please audiences today, unfortunately.
SPIEGEL: What do you mean?
Quasthoff: When I go to an opera performance and sit there while people are cheering and shouting "bravo," I sometimes ask myself what exactly they're cheering about. And I even see myself as an artist who also knows how to enjoy other people's performances. I remember a performance of Mahler's "Fifth Symphony" in Salzburg, with Simon Rattle and the Berlin Philharmonic. It was unbelievable how they played the Adagietto -- with such intensity and devotion. I left the concert hall in tears.
SPIEGEL: Is music a kind of magic?
Quasthoff: I don't know. Let me tell you a story instead. I was a member of the Windsbach Boys Choir, the first ensemble to sing the complete St. Matthew Passion in Israel after World War II. A man came up to me in the intermission. He was crying. He had a blue number tattooed onto his arm (a sign that the man had been imprisoned in a Nazi concentration camp). He hugged me and said, in German: "I'm speaking German today for the first time in more than 50 years. I lost my entire family." His wife, his children, his parents, everyone. "I heard you singing today, and now I know that Germany is a different place once again." When I gave a recital in Munich two weeks later, he came to my dressing room.
SPIEGEL: Was it liberating for you to realize that you had a voice, something that went beyond the disability?
Quasthoff: My wife Claudia is from Sonneberg in Thuringia. She was born in 1970. We've often talked about what German reunification was like for her. I always ask: "What's it like to grow up in a country like that, where you can't travel and you have so little freedom?" And she responds: "I didn't know anything else." It's similar with my disability. I was very lucky, because I was never treated differently in my family. When I misbehaved, I got slapped just the way my brothers did.
SPIEGEL: Are you saying that you had a normal childhood?
Quasthoff: I was taken everywhere and I wasn't hidden away -- which meant, of course, that I was also forced to deal with looks and, I suppose, stupid comments from an early age.
SPIEGEL: You yourself have a big mouth, if I may say so.
Quasthoff: That, of course, was always my weapon. I've become quieter now. It's possible to put things very clearly, concisely and sharply, even when you do it quietly.
SPIEGEL: Did you struggle against your fate?
Quasthoff: No, even if sometimes I was bitter about it. It was an especially difficult time for me when other boys started going out with girls.
SPIEGEL: Did you sing as a child?
Quasthoff: Constantly. Pop songs, opera, everything. I grew up with music. We had this music chest. It was broad and rectangular. There was a radio in the left bottom corner. The record player was on the right side, at the top, the kind where you can stack 10 singles on top of each other. By the time my mother would come home from the store, I was able to sing the songs on the singles.
SPIEGEL: How was your voice discovered?
Quasthoff: My father had also taken singing lessons once. He knew a little about music, and at some point he noticed that I had a great talent. My father said: I want Thomas to have something he can look forward to once a week. The way my brother looked forward to table tennis. That's why I got singing lessons.
SPIEGEL: Who taught you?
Quasthoff: My father went to see Sebastian Peschko, a fairly renowned and famous pianist at the time, who was the director of the department of chamber music and songs at the Norddeutscher Rundfunk (radio network) in Hanover. Peschko said: Okay, let's do an audition. But when he heard that I was a thalidomide victim, he said: 15 minutes, that's all the time I have. But then the whole thing lasted for more than one-and-a-half hours, and Peschko said: Okay, the boy isn't just talented. He is 100 percent made of music. He referred me to Charlotte Lehmann, a voice teacher, and I worked with her for 17 years.
