As a boy soprano he sang solo parts in recordings of Bach Cantatas under the direction of Gustav Leonhardt in his joint cantata cycle with Nikolaus Harnoncourt, done in 1985. As a boy he also sang in the boys' terzetto in Mozart's Zauberflöte in the Hannover opera house. He later studied singing with Peter Sefcik and Winfried Toll. He also studied piano (1979-1992, with Professor Märtson), contrabass (1988-1993, with Harald Wittig), and received the composition prize of the city Langenhagen in 1991.
