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: recorders, bagpipes (including historic versions), gemshorns, crumhorns, shawms, as well as harpsichord and piano.
He teaches recorder and bagpipes to children and adults in Switzerland.
He performs both as a soloist and with a variety of groups and is co-conductor of Lake Zurich Recorder Orchestra.
Josef has tutored on a number of courses in the UK.
