Posted on August 12, 2021May 20, 2025 by Dale Phillips Musical Strings Musical Strings by H.E. Huttig Originally published in American Lutherie #9, 1987 and Big Red Book of American Lutherie Volume One, 2000 In the realm of stringed musical instruments, logically enough, the quality and strength of the sound produced is largely dependent upon the strings that the instrument maker must use. To be sure, a string tensioned between two fixed points with no sounding box will scarcely make an audible response when plucked. On the other hand, the sound made by a finished instrument varies widely with the qualities of the strings that are used. There is a Persian legend to the effect that the stringed instrument concept was discovered by a person wandering in a desert. He came upon the shell of a tortoise. The bottom was lost but the top part still had dry sinews stretched across the hollow shell. The wind blowing across them made a musical sound. The Chinese gave us the idea of strings made of silk. There is still controversy as to whether the hunting bow with its vibrating string gave man the idea of a musical application or whether it was the other way around, the stringed instrument providing the idea of the archer’s bow.

Posted on June 23, 2021May 19, 2025 by Dale Phillips Finite Element Simulation of Guitar Top Vibration Finite Element Simulation of Guitar Top Vibration by Phil Banks Originally published in American Lutherie #18, 1989 The use of engineering finite element analysis software to determine modes and natural resonant frequencies of a guitar top can be a useful (albeit lengthy) process which, if used judiciously, can yield useful information to the guitar maker. As a graduate mechanical engineer and a guitar maker, I’ve always been interested in marrying the discipline of the luthier’s craft with that of science. I got that chance last year at the University of Sydney. While working as a programmer developing a Finite Element package, I was asked to produce a demonstration of the program’s capabilities. I decided to analyze a guitar top. Become A Member to Continue Reading This Article This article is part of our premium web content offered to Guild members.

Posted on June 23, 2021May 22, 2025 by Dale Phillips Pre-bending Herringbone Purfling Pre-bending Herringbone Purfling by John Calkin Published online by Guild of American Luthiers, June 2021 Herringbone purfling s a lot easier to work with if it is prebent before it is glued onto the guitar. This is best done after wetting it first. I always use a brush to spread glue on guitars. I keep a coffee cup of water handy at all times, along with an acid brush with the bristles properly trimmed back to the stiffness I like. I dip the brush, then hold it stationary as the strip of purfling is pulled across the cup underneath it. Soak the purfling well on both sides. This should take only seconds. Then the strip is pulled through a dry cloth. Soaking it for too long will encourage it to come apart as it is bent. Give the purfling a minute to absorb the water, then tape the butt end into the channel it will be glued in later. Wrap it carefully around the lower bout using a couple pieces of masking tape to hold it tight. More tape, as well as care, will be necessary to make it conform to the waist area. The wrap around the upper bout should be as easy as the lower bout. In the photo, you can see how much tape was used as well as the small fan used to dry the purfling before gluing it in place. All photos by John Calkin Herringbone will wrap around a moderate Venetian cutaway but do it gently and by stages. To be safe, the purfling can be wet and then sliced lengthwise on one of the glue joints using a single-edge razor blade. On a tight Venetian cutaway, the purfling must be sliced. On this tight-waisted jumbo guitar, the purfling was sliced from the top end to below the waist area to help coax this half-herringbone purfling to conform to the shape of the guitar. Sliced purfling doesn't need to be prebent but you might wish to wet it as you reach that portion of the install. Slicing the purfling can go awry and destroy it. Buy extra. ◆
Posted on May 6, 2021May 21, 2025 by Dale Phillips Lutherie: Art or Science? Lutherie: Art or Science? by R.E. Bruné Originally published in American Lutherie #1, 1985 Aside from the eternal “How do you bent the sides” question asked by non-makers, the most frequent point of curiosity seems to be that of other makers: “What do you think of the Kasha guitar?” I am somewhat surprised at this. Firstly, it doesn’t really matter what I think of the Kasha model. I don’t build it, and I would think this fact says enough. The second point is that the Kasha model and theories have been around for enough years (nearly twenty if I’m correct) that, were there merit in the model, it would have been almost universally adopted by makers and players by now. It took less than twenty years for the conservative makers of Spain to adopt the design ideas of Torres, for by the time of his death just before the turn of this century, nearly every Spanish maker with the exception of José Ramírez I was using his model. The reason for this nearly overnight conversion is obvious; the models of Torres were clearly superior to anything else available, and the musicians quickly accepted them. In fact, the makers who didn’t adopt his patterns went out of business. In contrast, one does not see musicians today playing the Kasha model. I know of no professional classical guitarists playing them, and in the nearly twenty years I have been involved in the guitar world, I have never been to a concert where a Kasha model guitar was played. Yet it seems there has hardly been an issue of the G.A.L. Quarterly without some article or reference to the Kasha model as if it were definitive, and desirable.

Posted on December 28, 2020May 14, 2025 by Dale Phillips A Review of Three Old Lutherie Books A Review of Three Old Lutherie Books with an Emphasis on Their Guitar Sections by Jan Tulacek, Alain Bieber, and James Buckland Originally published in American Lutherie #104, 2010 As we undertake this overview of three 19th-century lutherie texts, we recognize that much older documents were circulating from late medieval times. Some, such as the manuscript of Henri Arnault de Zwolle written in Dijon in 1440, already contained good descriptions of instruments, but to our knowledge, none had the goal to become a comprehensive “how to” lutherie handbook. From the Baroque era there are the important musical treatises of Michael Praetorius (1620) in Germany and Marin Mersenne (1635/36) in France, with good descriptions of our Western European string instruments. We also have a few fascinating descriptions of particular aspects of lutherie such as the Antonio Bagatella violin booklet of 1782, or the lesser-known Pierre Trichet viol making manuscript of 1640. And while the encyclopedia format of the Enlightenment Period of the middle 18th century never allowed extensive coverage of the topic, the French Diderot and D’Alembert books had wonderful drawings and interesting lutherie information. But in the late 1820s and early 1830s, still considered by many as the apex of the classical guitar in written music, we see two real lutherie “how-to” books appear, describing all the steps in the fabrication of the guitar. The first writer was Wettengel in Germany, followed a few years later by Maugin in France. In spite of many imperfections, they give a good understanding of the methods used in the two main centers of lutherie at that time, i.e., Neukirchen (now Markneukirchen) in Saxony and Mirecourt in Lorraine. A third important how-to book, by Hasluck, was published in the United States in 1907, but was likely written in the last decade of the 19th century. It is a very important work since it represents the first attempt to write a “how-to” lutherie book in English.
