Amongst the scientific techniques employed
in the examination of musical instruments, radiography is
one of the most widely-used and well-known.
An X-ray can reveal restoration work,
irregularities in the wood,the channels produced by wood-eating
insects and all the signs needed for the identification of
the state of preservation of the instrument under investigation.
Maestro Negroni is in charge of the
radiography team at the "A.Stradivari"International
Institute of Violin-Making (I.P.I.A.L.L.) in Cremona, where
radiography of bowed and plucked stringed instruments made
by the great masters of past and present is undertaken.
