After a few years as a primary school teacher, Josef began to study recorder in Switzerland in the 1980s.
He now plays a range of instruments – recorder, bagpipes (including historic versions), gemshorn, crumhorn, shawm, harpsichord, piano and electronic keyboard. He teaches recorder and bagpipes to children and adults in various music schools, and in individual lessons.
For a couple of years he played in a renaissance band. He currently performs with several groups, as well as performing as a soloist, and is conductor of ConTatto Recorder Orchestra Hoefe near Zurich.
In the UK, he has been a tutor on a number of courses: Northern Recorder Courses, Cheltenham Recorder Festival, and the Easter Recorder Course.
Josef runs his own course in the Swiss mountains and he is part of the team in other courses.
