In parallel, Karl Kaiser also studied theology, philosophy and musicology at the Universities in Bonn and Cologne, but then decided to become a professional musician. Since then, he has made an outstanding name for himself, not only as a soloist, a chamber and orchestral musician in the field of historically informed performance practice, but also as a pedagogue.
