Here's a thought that has occurred to me many times: "gee, I'd like to study x instrument in y museum or collection, I should check if there are CT scans of it" Much more often than not, there are not scans of the instrument in question.

As I was staring recently at tables of measurements of some rather ‘Nice’ Cremonese instruments, it struck me that the numbers that make up a violin are (or could in theory be) prime. For example: Body length: 353 Upper bout width: 167 Center bout width: 109 Lower bout width: 211 Distance between upper eyes of FFs: 41 Distance of lower lobe of FFs from edge: 13 Mensure: 193 (if you’re Del Gesu), or 197 (if you’re making the ‘Soil’) Width of scroll: 41 Narrowest point of scroll: 11 Length of scroll: 103 Neck length: 13 (cm) Coincidence? I think not! Is it a coincidence that th
