Geoffrey Fushi of Bein & Fushi Rare Violins invited an international team of experts, to study what is considered by many to be one of the world’s greatest violins, the 1741 “Vieuxtemps” Guarneri del Gesu. In addition, a 1707 Stradivari, a 1742 Guarneri, and a 1752 J.B. Guadagnini were also studied.
Among other tests performed by the team, Terry performed CT scans at Northwestern Memorial Hospital on the instruments. The process allows for an in-depth study of the instruments in a completely non-invasive manner. In the 30 seconds that it takes to scan an instrument, a wealth of information is obtained; providing valuable insight for modern makers.
The team was assembled by violin maker Joe Curtin and included Terry and D'Addario string designer Fan Tao. The project incorporated CT scans, acoustic radiation, modal analysis, and binaural recordings, as well as research into what accounts for instrument projection.
