Willow is one of the most used woods when it comes to lutherie. In the past it was mainly used for crafting blocks and linings, thanks to its firmness and workability. This tree grows in humid areas and in fact we often find it along
watercourses, where it propagates easily both by seed and by cutting. It reaches a height of 20-30 metres. It has a scaly bark, while the wood is tender and reddish-yellow: black willow (Salix nigra) is more suitable than white willow (Salix alba) because of its compactness.
