At the end of her chapter "Dudy wielkopolskie" Jadwiga Pietruszyńska-Sobieska lists "In total 215 dudziarzy and 20 koźlarzy" by name; She also informs us that "bagpipes are made by the pipers themselves", and that "Almost every player can make small repairs"; In Wielkopolska three categories of pipers (dudziarze i koźlarze) exist: [a]: non-professionals who play for themselves, and occasionally at weddings and parties for fun; [b]: professionals, who attend parties and "garlands" of their region, and [c]: professionals who, apart from serving their surroundings, leave to travel with their bagpipe during the "non-seasonal" period, and, rambling during a couple of weeks, go about areas where bagpipes are not known. When playing in the villages, towns and cities, they collect heavy earnings; For playing at a wedding (ca. 20 hours) a piper would earn 3-5 złoty [today’s rate?; ws], while a "1 day journey" would bring him 10-15 zł.; The bagpipe profession in Wielkopolska is hereditary, and individual manners of playing, the secrets of techniques and specific repertoire are passed on from father to son.
