From "prebirati" [to select / choose / play on a string instrument]; Studena; Probably a misinterpretation by Širola, who adds the presence of a non-return valve, and uses the same term for the chanter, which seems - taking comparative terms in consideration - to be more obvious; NB¹: ➺ Kanela; NB²: ➺ chanter (synonym of Prebiraljka).
