Wunderlich soon became known as a brilliant young tenor. He sang several roles in Mozart's operas, and gradually learned roles in many other operas, including Verdi's "Rigoletto" and "Don Carlo". There is an excellent recording of Mozart's "Magic Flute" in which Wunderlich sings the part of the Prince Tamino and the famous baritone Dietrich Fischer-Dieskau sings the part of Papageno, the birdcatcher.
