The skrabalai is a Lithuanian folk tuned percussion instrument consisting of wooden bells.
When the skrabalai is moved a clapper knocks at the wall of the trough.
The pitch of the sound depends on the size of the wooden trough.
The skrabalai is gouged from a piece of hard wood – oak or ash.
They used to tie a wooden bell of this kind on a cow's neck, thus making it easier to find the animals in a forest if they strayed from the herd.
