A book on the figure of Paolo Soprani, the inventor of the accordion industry, is being designed 100 years after his death. From 1863 he began to work on the production of bellows instruments, arriving at the beginning of the 1900s to transform the harmonica into a real accordion. An entrepreneurial adventure of which the whole musical world is a son. The volume will contain some unpublished photos, a story on the legend of the accordion and comments of all respect on today’s legacy. The Municipality of Castelfidardo and the Marche Region sponsor this new publication which will soon become a collector’s item.
