Bark whistle (a hazel branch with bark)

Another seasonal instrument/toy which is made in spring when the sap activates the trees and their branches are more humid.  That is when a piece of branch without knots and the bark is carefully removed from the branch like a tube.

 To do this an interesting ritual takes place, which consists in hitting the bark with the side of the penknife while some verses are sung or recited.

 These blows separate the bark from the wood and thanks to the fresh sap it can be removed in one piece. Beforehand, an incision is made in the bark and this acts as a bevel. A piece of the wood is cut and one side is flattened to make an air pipe which is then put back inside the bark using via the incision. The rest of the wood is also put back inside the bark from the other end, but not completely as a space is left as an air pocket and a hole/s can be made here.

This whistle was commonly used by children until recently.
