The study of instruments has come a long way. From the humble tape measure and callipers to sophisticated CT-scanning and dendrochronological analysis, our methods of non-invasive investigation and attribution have expanded in recent years to reveal even the smallest of details. This month’s poster for subscribers features Carlo Bergonzi’s ‘Baron Knoop’ violin of 1735, the measurements for which have been taken almost exclusively with micro-CT scans. It’s a technique that allows us to calculate distances between two points anywhere on the instrument’s surface, and thus provides remarkably accurate insights into its form and construction – as Rudolf Hopfner explains on page 28.
