T. Borman, 'Unspoiled Charm: The Vieuxtemps Guarneri del Gesu', The Strad, vol 1, May 2018, p. 38
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.

T. Borman, 'A Unique Pearl: The Vieuxtemps Guarneri del Gesu' The Strad, vol 2, June 2018, p. 30
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.

T. Borman, B. Stoel, 'Material Facts: A comparison of density in wood used by classical makers throughout Europe' The Strad July 2012, p. 47
Were the old Cremonese violin makers really using better woods than those available to other violinmakers in Europe?

T. Borman, B. Stoel, R. deJongh, 'Wood Densitometry in 17th and 18th Century Dutch, German, Austrian and French Violins, Compared to Classical Cremonese and Modern Violins' Public Library of Science, vol 7, issue 10, October 2012, p. 1
Terry's latest study finds no significant differences in median densities between modern and classical violins, or between classical violins from different origins.

T. Borman, B. Stoel, 'CT and Modal Analysis of the Vieuxtemps Guarneri del Gesu' The Strad, January 2011, p. 68
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

T. Borman, B. Stoel, 'Review of the Uses of Computed Tomography for Analyzing Instruments of the Violin Family with a Focus on the Future', VSA Papers, vol XXII, issue 1, June 2009, p. 1
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.

T. Borman, B. Stoel, 'A Comparison of Wood Density between Classic Cremonese and Modern Violins', Public Library of Science, vol. 3, issue 7, July 2008, p. 1
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.

T. Borman, J. Loen, A. King, 'Path Through The Woods', The Strad September 2005, p. 68
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.

T. Borman, S. Rawley, 'High Resolution Photography for Instrument Makers', VSA Papers, vol. 1, issue 1, June 2005, p. 145
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.
