A bulky tree trunk lies on the Bachmann family’s workbench. You would hardly believe that one day expert musicians would be able to coax beautiful tones from this piece of timber. But the transformation begins as the alphorn makers Walter and Hansruedi Bachmann start shaving off wood, layer by layer. With lathes and planes they shape and polish the log until it has the perfect curve of an alphorn. Only then do they hollow out the interior, working for many slow, painstaking hours until the floor is covered with wood shavings. Special guided tours provide an insight into the alphorn makers' art. At the end, visitors can even try blowing a freshly made alphorn themselves.
