A decade ago, François Denis'south Traité de Lutherie showed how the old Italians used Euclidean geometry to blueprint their instruments. Now a calculator program based on these principles allows luthiers to construct and adapt patterns chop-chop and easily. Its creator, Harry Mairson, explains the genesis of Digital Amati

Agreement the principles backside the Digital Amati project can be quite challenging at first glance; however, they are all based on Euclidean geometry, taught in schools since time immemorial. Information technology is possibly extraordinary that for the past 300 years, violin makers have adhered so closely to the works of the Italian masters without understanding the geometric principles behind them. Stradivari made his 1716 'Messiah'; Vuillaume made exact copies of it, and many makers after him carried on in the same vein. Sam Zygmuntowicz has joked that thanks to inevitable 'pencil creep', 19th-century French violins slowly increased in size every bit their makers slavishly traced each other'southward templates to make new ones.

Guide and inspiration: François Denis'sTraité de Lutherie

The inspiration for Digital Amati came from François Denis'due south revolutionary 2006 book Traité de Lutherie: the violin and the art of measurement. In it, Denis took important steps towards integrating the dual, refined skills of design and copying – ii stages that he refers to as the 'classical' and 'romantic' eras of violin making. Through the careful reverse-engineering of item stringed instruments, using only the geometric constructions possible with a straightedge and compass – near significantly the idea of using Euclidean, proportional methods – Denis provided a vocabulary and a geometric vernacular for their conception and creation. As a outcome, he put an important and practical analytical tool in the hands of every luthier.

Traité de Lutherie is one of the best books I've ever read: a polyglot potpourri of art and architecture, mathematics and musicology, philosophy, history, and science. When the Ashmolean Museum had its blockbuster exhibition of Stradivari instruments in 2013, its catalogue paid implicit yet unmistakable homage to Denis'due south contribution: it read, 'It is now recognised that what first distinguished Cremonese instruments from those fabricated in other centres was a geometric formality of blueprint and proportion borrowed straight from the architects, painters and many other designers and craftsmen of the Renaissance.'

A generation earlier, the writer and craftsman Kevin Coates wrote in his 1985 volume Geometry, Proportion, and the Art of Lutherie, that 'lutherie will never again reach the same grace of enlightenment, of genuine creativity, unless it tin can return to […] the lost principles that nourished the genius we at present mindlessly, or rather, soullessly, seek to replicate'. Denis'southward contribution was a timely, informed response to Coates'due south critical assessment. It has given us a greater insight into what some of those principles were: fundamental geometric ideas, utilised and shared past Renaissance artists and craftsmen, which also grounded the creations of luthiers. Their collective piece of work was not only a beautiful production of creative imagination: information technology was principled, and based on geometric methods.
