Gaita-de-foles (f)
(with) definite article: aBagpipe, mouth-blown: 2 stocks (a: single chanter / b: drone)
Its full name, used only to distinguish this instrument from the other Portuguese Gaitas (whistle, 3-holed flute, and shawm); NB: Note the defective punctuation (Gaita de foles) in several sources; According to Marcuse, who fails to reveal her source, the instrument is also called gaita galega (which I strongly doubt; Already in the 1990s, however, I was informed that it would be rather hard to find a Gaita made in Portugal [Oliveira mentions (p.327) "the decline of local manufacturers, who are practically extinct"], and that many Portuguese pipers would buy their instrument from a Galician maker [e.g. Obradoiro Seivane; ws]; In my opinion, only such instruments can, justly, be called "Galician"); NB¹: ➺ Brazil; NB²: ➺ homonyms.
