The Swiss counter-tenor anf former boy soprano, Terry Wey, knew that he wanted to become an opera-singer, after seeing his first and still favourite opera, Il Trovatore by G. Verdi, at age 4. He joined his first choir, The Berner Kinderchor, at age 6 performing in La Boheme in the Bernese City Opera house and other various concerts. He was the soloist in Elijah (Felix Mendelssohn) in Berne, Zürich and Basle. At age 7, he joined Knabenchor Roggwil under R. Favre. Here he performed the part of first page in W.A. Mozart's Magic Flute in Baden for the first time, followed by concert tours through Italy singing J.S. Bach's St. Matthews Passion (BWV 244) with the Orchestre Symphonique Neuchatelois and performances at the "Goetheanum" and the "Tonhalle" in Zürich.
After seeing a TV-documentary on the Wiener Sängerknaben, Terry Wey auditioned and was accepted to attend Vienna's preparations-choir. From 1994 (or 1995) until 1998, he was a member of the Schubert choir, one of the four concert choirs of the Wiener Sängerknaben performing in more than 300 concerts. He soon became a soloist, eventually singing solos in all four choirs in tours around the world. With the choir he was soloist for W.A. Mozart's Coronation Mass and Schubert's Magnificat.
