Martin Hahn is a versatile musician who puts his career on various pillars. His most important pillar is his position in the Badische Philharmonie Pforzheim, the orchestra that accompanies all performances of the music theatre at the Stadttheater Pforzheim. The Badische Philharmonie Pforzheim gives numerous guest performances in cities in southern Germany and Switzerland, which do not have their own music theatre, and thus make an important contribution to the cultural offerings in rural areas. In addition, the orchestra has a central position in the concert system of the city of Pforzheim.
