WOOD
The use of ebony for fingerboards, tailpieces, pegs, endpins and chin rests in instrument making has long invited questions about ethical and environmentally friendly sourcing. Swiss start-up company Swiss Wood Solutions claims to have developed a new beechwood product, Sonowood Black, that offers a ‘sustainable alternative’. Beechwood is widely available in central European forests, say head of research and development Munish Chanana and chief product officer Christian Lehringer, but because it is naturally softer and less dense than ebony, it is usually unsuitable for making instrument parts. Through a new ‘thermo-hydromechanical process’, they claim to have modified beechwood so that its acoustic properties resemble those of ebony, by exposing it to high compression forces and temperatures. These, they say, increase the wood’s density to 1,200–1,400kg/m 3 and minimise its natural tendency to swell and shrink.
