STEINWAY and SON Grand Piano Model-A (RENEWED)

Rim
Made entirely from hard rock maple and mahogany; laminations; continuous bent, both inner & outer form one single rim; unequaled strength and stability.

Braces
4 solid spruce; spruce provides tensile strength with less weight. Maple dowels fasten braces to rim producing a single homogenous foundation upon which is built the entire tonal component. A cast iron treble bell, affixed to rim’s underside at treble bend, holds plate firmly in position by means of a steel bolt. The S & S iron wedge anchors brace ends securely to crossblock assuring permanent rim posture.

Soundboard
Created like the soundboard of violins to give a free and even response throughout the entire scale, it is so constructed as to be 9 mm thick in the center and tapered to 6 mm as it approaches the rim and outer case before being DOUBLE CROWNED. This design permits complete freedom of movement, while acting as a homogenous unit to displace a greater amount of air, thereby creating a richer and more lasting tonal response. Close-grained, quarter-sawn Sitka or European spruce, a wood having unusual stability and vibrance under stress and vibration, is used exclusively for the soundboard.
