The black poplar is perhaps the most common of poplars widespread in Italy and especially in the north, you can also find it in the mountains but unlike the white poplar is much less delicate and grows to a very considerable sizes. It is most commonly used for the production of paper, for ornamental purposes and along the streets. Thanks to the large size that reaches its trunk are numerous instruments such as cellos or basses with the base in one piece. As the white poplar its fiber is very elastic and returns a clean sound and rich in harmonics and for this quality is also used for smaller instruments such as the viola and the violin by the best luthiers of antiquity with excellent results. Among its variants there is the Lombardy poplar which is easily recognizable from the shape of her hair similar to that of the cypress but unusable in violin making by the growth of the trunk very rich in branches.
