From Anton Giulio Bragaglia, »Danze popolari italiane« (Roma, 1950), in which it is mentioned as "l'arce sorvellina"; NB: According to Mauro Gioielli it is an alternative [or incorrect?] spelling of Sordellina [➺ “Miscellanea zampognara” below], which may well be the case (!), but unfortunately he fails to support his judgement with an explanation or source.
