Read Graham Caldersmith’s memoriam
Twenty-nine-year GAL member Graham Caldersmith started out studying reentry dynamics of spacecraft, but ended up studying the acoustic dynamics of guitars and violins. He lectured at the 1982 and 1998 GAL Conventions. Recently he has focused on developing a classical guitar family and refining the sound of violins made in Australian tonewoods.

▪ Graham Caldersmith’s articles in GAL publications go back a full thirty-five years, earlier than American Lutherie magazine itself. He’s located in a tiny town in the hinterlands of New South Wales, Australia. He uses his scientific training to develop innovative classical guitars, and has long been a leader in the effort to develop a family of guitars of different sizes and musical ranges. Our globetrotting reporter asks about his latest thoughts and methods, which include carbon-reinforced lattice bracing.

▪ Dickens did R&D work at Bell Labs in his day job, and was among the first to look at the functioning of the guitar from a mathematical vantage point. He was known for his inquisitive mind and willingness to share his knowledge with others.

▪ Caldersmith offers this article as an aesthetic link with his more scientific treatise in AL#58. The shape of a fiddles sound can be explained technically, then interpreted into a wooden shape that must please the maker’s artistic eye. If you’ve been scratching your head over the meaning of all the technical gobbledygook, this may be the information you’ve been waiting for. With a drawing and 11 photos of the carving process.

▪ Everyone knows that the most responsive instruments often teeter on the edge of self-destruction from string tension. Building fine-sounding instruments that will also have a reasonable lifespan is one of our general goals. Caldersmith takes a scientist’s view of the violin and decides that arching design is the key to longevity, while an understanding of free-plate tuning is needed to release the tonal qualities the luthier seeks. He furnishes 7 charts and diagrams to help make his case, as well as a photo of his Australian self. But what we all want to know is if a pursuit of science will eventually enhance our luthier’s intuition. Is it better to think or to feel? Do we really have to choose?

▪ Caldersmith is working to expand the voice range of guitar ensembles, both classical and steel string. With 4 photos and frequency response graphs. The first installment of Caldersmith’s work with a classical guitar family came way back in AL#18.

▪ Is it possible that old fiddles aren’t superior? Yes, but the only people who want to believe that it’s true are the contemporary violinmakers. Human nature would rather cast its faith to a mythical past than deal honestly with the present. Or not. Caldersmith doesn’t pretend to settle the debate.

▪ Caldersmith discusses the efficiency and pattern of sound radiation in the classic guitar produced by the four lower resonance modes, which he calls monopole, cross dipole, long dipole, and tripole. Mentions Tom Rossing, Gila Eban, Paul Wyzskowski, Fred Dickens, Michael Kasha, Richard Schneider, and Greg Smallman.

▪ The “Young’s Modulus” of any piece of wood can be calculated, giving a result measurable in frequency. Comparing the Young’s Modulus of a wood species with unknown qualities with a chart of other species of known characteristics can tell you what to expect before any instrument work is commenced. Here’s how to calculate the Young’s Modulus of any piece of wood you have on hand. With 1 drawing and a sample wood chart.

▪ The Sacconi technique of sealing fiddles with silicates has not been widely accepted. Nevertheless, the author explains how he has successfully used silicates to seal and harden violin wood before varnishing, as well as the use of vernice bianca (basically whipped egg whites) to act as an interface between the silicate and the varnish.

▪ Caldersmith loves the scientific aspects of instrument design, and offers this primer to help explain what’s going on in an excited classical or steel string guitar without going off the scientific deep end. The most interesting part is that in his update (17 years later) he has reversed is position on how to use this information. Information doesn’t change as much as how we use it, and we can’t use it if we don’t understand it. That, in a nutshell, is the acoustician’s tenant.
