Varzi lies in the center of the Stàffora Valley, in the heart of the Oltrepò Pavese. The village is part of the culturally homogeneous territory of the Four Provinces (Alessandria, Genoa, Pavia, Piacenza), characterized by common customs and traditions and an important repertoire of very old music and dances. The main instrument of this area is the Apennine fife, which accompanied by the accordion, and once by the müsa (Apennine bagpipe), leads the dances and enlivens the festivals.
