Abstract
In 1979–1980, four pairs of top and back viola plates, finished and tuned according to Hutchins' plate tuning method, were measured for the frequency and damping of modes ♯1, ♯2, and ♯5 and weighted carefully. Two of the above pairs were tested with filler on, and two “in the white” with subsequent application of filler. Each pair of top and back plates was then glued to its own set of ribs and six coats of violin oil varnish applied. The four varnished “corpuses” were hung in an unheated attic for 5 years. The plates were then removed from their ribs and a similar series of tests applied. The measured changes in mode frequencies, damping, and overall weight of each plate will be presented and implications for violin making discussed.
