Materials
The choice of wood in the construction of instruments is all important. From an acoustic point of view it is desirable that the wood be as light as possible and yet have a high degree of stiffness. Lightness is not achieved by making violin plates thinner but by using wood that has a lower density. Lower density yields lower mass for the same amount of wood of higher density. With the right stiffness this plate will function more efficiently. The same principals apply in formula one racing design where a light weight but adequately stiff chassis is preferable over a heavier, equally stiff one. I have found that Englemann Spruce possesses these characteristics and have used it very successfully in building violins. It is native to North America and grows in the western mountain areas of the continent. I have also had success using Douglas Fir which though somewhat denser works well with violas. This is a tree that is also unique to North America. Red Maple, also indigenous to North America provides suitable material for ribs , backs and necks. Again the less dense is acoustically preferable. Red or soft maple can be beautifully figured wood. Whatever materials are used they must be adequately air dried for a number of years. A large drive shed at the back of the property provides a great space for the purpose.
