| The soundboard in Fazioli Pianos
is built with the precious wood from Red Spruce from Val di Fiemme
in the Western Italian Alps. This is a particularly precious spruce tree:
The main characteristics of this type of wood are:
- For the high resistance to flexing
- For the low, specific weight
- For the regularity in the distance between rings
This is obtained by gluing the red spruce shafts which are cut on the quarter
of the trunk and with a variable width, between 8 and 12 cm and with a 12 mm thickness.
The soundboards are seasoned in a climatically controlled
chamber for about two years, before they are assembled. Measurements from the
center to the extremities are between 9 and 6 mm. This allows for better mobility
and greater volume. The ribs are also made of red spruce and are tested for their
flexibility before they are glued onto the soundboard in order to guarantee their
mechanical characteristics.
The strong, double curvature, obtained by gluing perpendicular shafts (made
of the same wood). The bridge, not only offers a counter thrust to the string's
pressure (1000 lbs) but also make the soundboard more rigid in order to "move"
larger quantities of air and project the sound further away. The soundboard is
glued to the structure, which is previously prepared in order to create a counter-tension
from the edges to the center. The soundboard acquires the shape of a lens.
