This is a presentation by violin maker Kevin Kelly about the Four Circle system, showing a stepwise progression from the earliest to the latest Cremonese violin designs, from a 1550 Amati to a 1741 Guarneri ‘del Gesù’ and the Stradivari ‘P’ form.
The presentation uses Harry Mairson’s Digital Amati computer program
