Sjaak Elmendorp
▪ The technology and fashion of wooden instruments move forward inexorably, although whether that forward motion is the same as improvement can be a matter of debate for decades or centuries. Elmendorp made what he calls a faithful impression rather than accurate reproduction of a 1907-style Gibson L1: small body, carved top, floating bridge, round hole.

AL#150 p.14
Sjaak Elmendorp
▪ When you tighten the strings on an archtop guitar, the neck lifts forward and the action height increases. At the same time, the bridge pushes the top down and the action height decreases. Its a win-win! So you can just feel lucky about it and proceed naively along your life path, or you can do what Elmendorp did: get a bucket of water, a piece of wire, and a dial indicator; collect some data; then crunch the numbers.

James Buckland
▪ Baroque guitars were 5-course instruments. That is, they had ten strings in five pairs. Then suddenly here comes the 19th century and guitars had six single strings. Yadda yadda, now its today and everything is normal. The real story is a lot more interesting than that and it actually involves a missing link; the 5-string guitar. Luthier, guitarist, and scholar Buckland lays it all out for us.

Roger Haggstrom
▪ A hundred and some years ago, Swedish folks sat around the house all of a dark winter and sang hymns together, accompanied by the strummings of cheap mass-produced guitars. Those days are gone, but a lot of the guitars are still hanging on the walls of old houses. Roger Häggström has made a business of restoring them to useful condition and modifying them to sound and play better than they ever could have. He restores and modifies. Restomods. Mentions the Levin guitar company.

Less noticed by the public, but of special importance to luthiers, was Bream’s work with a handful of classical guitar makers from whom he commissioned the fine instruments that he played.

And it has a lot to do with the resonances of acoustic instruments, which has a lot to do with how they sound. Anyway, in this largely math-free presentation, Professor Mark gives us the scoop.

Juan Oscar Azaret
▪ Tap on a guitar. Or listen to just the first fraction of a second as you pluck a note. Those tiny samples contain a wealth of information. Our brains already form an impression of the guitar’s sound, long before the first second has elapsed. Computers can reveal the math behind the music and help us understand and visualize what is happening. Good basic info about the FFT, that is, the Fast Fourier Transform, and how the information in a guitar tap can be viewed in the time domain or the frequency domain.

Federico Sheppard
▪ In his youth, before Federico Sheppard found his calling as a luthier, he was a mere physician working for the Olympic Games. One day he heard a classical guitar being played on the radio of his car. It shook him to “his inner core being” as Lord Buckley would say, and changed the course of his life. And now he has finally made the pilrimage to Chile to visit the shop of the man who made that guitar, Rafael Mardones, and his son, Rafa Jr.

Greg Byers
▪ So you made a classical guitar, and it sounds good. You want your next one to sound good, too. You want your output to be consistently good. How do you do that? After decades of lutherie experience, Byers has developed a method of recording the frequency responses of the soundboard at each major stage of construction. Does the tap-tone of the raw top set tell the whole story? No, but it can help you steer the project to a successful conclusion.

▪ There are times when a luthier may want to draw a good long-radius arch. If jury-rigging a 25-foot compass seems like a hassle, you may have been tempted to just bend a straight stick a little and call it good. Turns out that’s a better solution than you may have thought. This article evaluates several techniques and gives the math that undergirds them.

He’s located in a tiny town in the hinterlands of New South Wales, Australia.

Dana Bourgeois
▪ Taken from his 2008 GAL convention lecture, the author explains the basic functioning of a guitar top and how he manipulates the plates and braces to achieve the sound he’s after. Mostly, he says, he’s after the most different tap tones that the top and back can produce, but there are many other details given along the way. Bourgeois is often regarded as one of the champions of tap tuning. With 9 photos, 6 charts, and a bunch of diagrams.

Alan Carruth
▪ Carruth built a classical guitar with many ports cut in the side. By closing the ports with corks in various combinations he tested the usefulness of sideports and tried to establish the physics behind their use. Though this guitar did not make a believer out of him, he admits that his results are somewhat inconclusive. With one photo and a slew of charts and figures concerning the air modes of his guitar with various sideports open.

R.M. Mottola
▪ It’s not necessary to understand the physics of sound to be a great instrument maker, but it can’t hurt. Many of us would like to believe that we succeed using experience and strong intuition and don’t need science. Maybe an analytical mind just gets in the way, no? Or maybe the science guys are just smarter than the rest of us and we need an excuse not to stand in the same light that they do. Who knows? Anyhow, the Helmholtz resonance is the lowest vibratory mode of an instrument, though not necessarily the lowest note that instrument is capable of. All the rest of sound physics is built on top of the Helmholtz resonance, and Mottola devolves the science enough for the rest of us to understand. It’s fun but in the end it’s not clear that it really matters. For the few among us with operational math brains all the formulas are presented in a sidebar.

▪ The right side of the brain is creative and the left side is analytical. It’s nice when they can work together, but for most of us one side or the other is dominant. The reviewer (who is admittedly left-brained) would like even right-brained luthiers to read this book, though he admits that they may struggle. Intelligent people shouldn’t ignore any source of information that may improve their work. Those who become luthiers to escape from real work may not grasp this concept.

▪ The way in which the guitar body responds to the driving forces of a vibrating string is a very complex subject.

Graham Caldersmith
▪ 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.

Gila Eban
▪ Eban offers an eloquent argument for trying the Kasha system in your own shop, as well as many details of her own guitars. A page-sized blueprint is included. She maintains that there is a philosophy and an aesthetic behind the Kasha design that is self-revealing and pleasing to work with, and that the design will always be under-realized until a larger number of builders have come to understand and absorb it.

Graham Caldersmith
▪ 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.

Paul Wyszkowski
▪ The author uses a light approach to science to explain the function of the classical guitar top and attempts to translate the functions of physics into a form the luthier can use at the bench.

Roger Siminoff
▪ The author considers X braces as structural elements and tone bars as tone adjusters, and that tone color can be altered by the stiffness of the tone bars and the size of the soundhole. Despite the possibilities, no examples for use are given.
