With every new musical and technical challenge craftsmen and avid gamers strived to more beneficial the brand new and by far not perfect instrument. This development is comparable to biological evolution of living species. Usually it was in small steps, shows forking, interdependencies of workshops and sometimes dead ends. Today a few strategies survived, on the one hand the German System a progressively improvement of Denner's System, it really is played mainly in Germany and Austria.
