The Strad Magazine - Unspoiled Charm: The Vieuxtemps Guarneri del Gesu
Currently the world's most expensive violin, the 1741 'Vieuxtemps' Guarneri 'del Gesu' is in a remarkable state of preservation, cinsidering it has been in use for most of its life. In the first of a two-part article, Terry Borman examines the instrument to discover what it reveals about its maker.
The Strad Magazine - A Unique Pearl: The Vieuxtemps Guarneri del Gesu
In the second of two articles, Terry Borman discussed the ribs, purfling and scroll of the world's most expensive instrument, with additional comments from its current player, Anne Akiko Meyers, and expert acoustical and technical analyses.
The Strad Magazine - Material Facts: A comparison of density in wood used by classical makers throughout Europe.
Were the old Cremonese violin makers really using better woods than those available to other violinmakers in Europe?
Public Library of Science - Wood Densitometry in 17th and 18th Century Dutch, German, Austrian and French Violins, Compared to Classical
Cremonese and Modern Violins
Terry's latest study finds no significant differences in median densities between modern and classical violins, or between classical violins from different origins.
The Strad Magazine - CT and Modal Analysis of the Vieuxtemps Guarneri del Gesu
This article discusses measurements of the vibration modes and geometry of the 1741 'Vieuxtemps' Guarneri 'del Gesù' violin made using computed tomography (CT) and modal analysis technology. During our research we also studied the 'Jarnowich' Guarneri 'del Gesù' of 1741 and the 1707 'Cathedrale" Stradivari
VSA Papers - Review of the Uses of Computed Tomography for Analyzing Instruments of the Violin Family with a Focus on the Future by Terry M. Borman & Berend C. Stoel
X-ray computed tomography (CT) has proven to be a valuable tool in studying antique, as well as new, instruments of the violin family. This article reviews the history and workings of CT and then focuses on the future and the relatively new method of quantitative analysis of CT images. Potential new uses for violin makers of the obtained data are presented.
Public Library of Science - A Comparison of Wood Density between Classic Cremonese and Modern Violins by Berend C. Stoel and Terry M. Borman
Classical violins created by Cremonese masters, such as Antonio Stradivari and Giuseppe Guarneri Del Gesu, have become the benchmark to which the sound of all violins are compared in terms of their abilities of expressiveness and projection. In this paper, new test methods are examined which allow the non-destructive examination of one of the key material properties, the wood density, at the growth ring level of detail.
BBC Radio - Science versus the Stradivarius
Interview with Terry Borman, Colin Gough, Tasmin Little, Brian Moore, Joseph Nagyvary, George Stoppani
The Strad Magazine - Path Through The Woods by Jeffrey S. Loen, Terry M. Borman and Alvin Thomas King
What secrets lie beneath the surface of violins by the great 'del Gesù'? Using the latest techniques to reveal the hidden contours of wood density.
VSA Papers - High Resolution Photography for Instrument Makers by Terry M. Borman and Scott Rawley
This article is intended to inform the typical working luthier about some of the more important aspects of photographing instruments of the violin family. We also describe a portable system that can enable those who need to photograph instruments away from the shop setting to arrive at satisfactory results.
The Journal of the Acoustical Society of America - The Violin Bridge as Filter
The violin bridge filter role was investigated using modal and acoustic measurements on 12 quality-rated violins combined with systematic bridge rocking frequency f(rock) and wing mass decrements deltam on four bridges for two other violins.
