Posted on August 11, 2021May 16, 2025 by Dale Phillips The Anti-Murphy Concert The Anti-Murphy Concert by Alan Carruth Originally published in American Lutherie #39, 1994 I recently had the privilege of attending a somewhat unusual concert by the Tokyo String Quartet, with some acoustics experiments thrown in. Or maybe it was a physics lecture with live accompaniment? And then there was the quiz show part... I guess I’d better explain. The whole thing seems to have started with the coming together of a number of good ideas. One of the first was a plan by the Acoustical Society of America to produce an educational video on acoustics for grades K–12. This, of course, would require money to do, and the suggestion was made that a benefit concert be held. The members of the Tokyo String Quartet were contacted, and graciously consented. So far, so simple. But remember, we’re dealing with acousticians here. Why not use the opportunity to do a little research? For one thing, while the acoustics of empty halls are reasonably well understood, nobody is really sure what happens when you put in the audience. Since the object of most concert promoters is to have as large an audience as possible, and nobody likes to listen to music in an acoustically lousy hall, it seemed like a good subject for an experiment. And how about that violin thing; you know old vs. new and all? And while we’re at it...

Posted on August 11, 2021May 14, 2025 by Dale Phillips Violin Free Plate Mode Tuning Reprised Violin Free Plate Mode Tuning Reprised by Edgar B. Singleton Originally published in American Lutherie #103, 2010 In the early stages of violin building, the outline of the top and back plates are established, as is the contour of the outside surfaces. Wood is removed from the underside of each plate until the thickness of the plate is a millimeter or so thicker than expected to be in the final form. The f-holes are cut; the bass bar and purfling are installed. The time has then come to graduate the plates, i.e., regulate the thickness of the plates in an attempt to assure that the finished violin will have all of the desired characteristics. Some builders “graduate to thickness” by carefully copying thickness measurements from important old violins. They listen to the pitches of tap tones and have learned ways to adjust these pitches. They have also learned to bend and twist the plates in their hands with the goal of assessing elastic properties, using experience to relate these “felt” properties to the finished violin.1 These processes involve as much art as science and require many years of carefully evaluated experience. This experience is very difficult to articulate to the novice builder. One process associated with graduating the plates that is related to tap tones is referred to as “free plate mode tuning.”2 3 4 5 The following exposition is intended to help instrument builders, familiar with the material contained in the above references, understand the basis of free plate mode tuning as it is based on some simple physics and to provide a technique to fine tune each mode (tap tone) individually. The purpose of this paper is to give the builder a new basis on which to visualize where, and to understand why, to remove wood if one wishes to tune the free plates of a violin.

In soft woods, the fibers stretch and compress more easily than they do in hard woods, so soft woods can successfully be bent to smaller radii than can hard woods before the wood fractures. Thin maple strips used to form violin ribs must be bent to small radii at the corners. Maple being a hard wood, there is a tendency for fibers along the inner surface to strongly resist compression.

Warnings: 1) Steel wool destroys strings with repeated use; 2) Steel wool contains an oil to prevent its rusting. This oil transfers to the bow hair, the case, the blanket and everything, compounding the bow skip problem. The solution is to stop using steel wool and start with fresh hair and a cleaned case plus new strings. Spotlight on the Bow Bug. Bow bugs are in Indiana, New York, Miami, and all points! A bow used once per day will not be cut up by the bow bug; he (it) hates light, and will not park on a bow used or kept in light. The bow case closed for a few weeks is an open invitation for him to munch on the rosened hair. The bug can get in the case at any time, or never. It is not predictable. However, if you have chunks of hair cut in the case, be sure to vacuum the case thoroughly and add two plain moth balls to the closed case.

One reads 12:00, another says 11:55, another 12:05. Only one can be right, and it probably isn’t a bad guess that none of them is right. Searching for the right varnish is like being in that clock shop.” “A man could make 150 more violins in his life if he wasn’t so worried about concocting some witches brew. He would do well to spend his time learning to make a fine violin.” Become A Member to Continue Reading This Article This article is part of our premium web content offered to Guild members.
