The first phase in constructing a piano begins by forming the rim, which is made in two layers, internal and external.
The internal rim, which is lower, is made by stacking together 5mm thick lengths of solid maple, which is then bent around special moulds to form its characteristic shape.
The load-bearing frame of the piano is attached to the internal rim, a front cross-piece is applied and a metal joint fitted; the reinforcing bars are then fitted into the joint and connect to various points on the rim.
The bars are made of three lengths of spruce which are glued together in a way to guarantee maximum stability.
The sound board is made by laying several lengths of red spruce, cut from the trunk using the quarter sawn method, side-by-side and gluing them together.
After passing a rigorous selection process the 1cm thick lengths, which are between 8 and 12cm wide, are chosen by the highly specialised Fazioli technicians.
