Abstract
A violin has been constructed with a graphite-epoxy sandwich plate replacing the usual spruce top plate. This substitute plate is similar in design to that previously described for a guitar application [D. W. Haines, N. Chang, and D. A. Thompson, J. Acoust. Soc. Am. 55, S49(A) (1974)]. Modern methods of violin design and construction produced an instrument with qualities which compare favorably with those of superior violins constructed entirely of wood. Frequency response curves and mode shapes are presented of the detached graphite-epoxy plate. Shown also are frequency response curves of the complete instrument. Comparisons with similar tests of high-quality wood plates and instruments are also given. The new violin will be available for examination.
