Musical instrument simulating charango

摘要

A charango (a ten-string musical instrument of the guitar tupe originating in Bolivia and prepd. from an armadillo shell) with improved musical characteristics can be produced from glass-fibre reinforced resin, with the mould for the sound box formed from the actual shell of an armadillo, so that its scale structure can be reproduced accurately on the moulding. The shell is coated first with an anti-adhesive agent and the mould is built up on it. The sounding body is then moulded normally from glass fibre fabric and epoxy resin together with suitable pigments.Problems of distortion associated with armadillo shells are avoided.
