Zubivka
The zubivka (, ) also known as a (Skosivka, Skisna Dudka, or Frukanka).
The zubivka is considered one of the oldest folk wind instruments in Ukraine and is found primarily in the Carpathian region.
It was first described by wandering Arabic scholars in the 11th century. This instrument is very similar to the telenka, only instead of having a fipple, it is played like the sopilka or frilka, by having the breath break against the side of the pipe. This surface is wedge-shaped. The zubivka is usually approximately 60 cm (24 in) long.
