For the construction of stringed instruments spruce and maple are used for centuries almost exclusively. Main reason is the good availability around the historic craft centers in Bavaria and the Alps, very important is the excellent technical suitability of these species too.
Optical criteria make notably maple for instrument makers so valuable. The wood is diffuse-porous and has due to the growth a smooth, easy surface to be polished, it is easy to process and often has a wavy grain – the “ flaming“ – which is by changing light refraction under the paint surface particularly bright to bear.
The outlined relationships and material properties are important. However, a variety of other factors such as the geometry and shape, surface treatment and finally the sound setting are essential.
