Single labial pipe. It has six finger-holes(škulje, škuje) and often a thumb hole drilled in line with the first. The 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. Today, in the musical practice in Istria it is used to a much lesser extent than other instruments. Specimens found in the Istrian museums (Pazin, Labin, Porec) show that the production of the sopelica used to be widely distributed, especially in central and northern Istria.
