Description
Double-bore monoxyle labial pipes - made from a single piece of wood. There are four holes for playing (škulje, škuje) on the right pipes and three on the left, and usually on the right pipe there is a thumb hole drilled in line with the first. There are few specimens with a different layout and number of holes. Each bore is closed at the top with a wooden block, with a narrow windway left for the air to strike on the edge of the labium on the upper side.
