Bosnian maple is a type of Acer platanoides , a European mountain maple indigenous to former Yugoslavia. It was a very high grade of maple, very light and very strong, according to some the best wood in the world for making violins, [1] as it had the finest resonance. [2] The classic Italian violin makers probably used wood from Tyrol, or northern Yugoslavia, or Switzerland. [3] The maple has mostly been used for the back plates. [4] It was used by the Gagliano family of luthiers. Portuguese violin maker António Capela uses the Yugoslavian spruce and maple. [2]
