According to Stainer, "Fétis remarks that when some of these poor sampognatori or sampognari migrated to Paris some years ago [i.e. in the 1860s?; ws], in the hopes of getting a livelihood, they were popularly called pifferari, but, of course, wrongly so, as the pifferari, were oboists, not bagpipers". NB¹ (WS): Stainer's conclusion is, however, an unfortunate misinterpretation, because the term actually refers to a duo of a shawm player accompanied by a bagpiper (➺ Pifferari !; Compare Musa, Zampogna a chiave, and Zampogna !);
NB²: ➺ similar terms.
