Posted on March 6, 2024March 7, 2024 by Dale Phillips Building the Kamanché Building the Kamanché by Nasser Shirazi Originally published in American Lutherie #4, 1985 and Big Red Book of American Lutherie Volume One, 2000 The word kamanché in the Persian language (Farsi) means “small bow.” This instrument, with varying shape, size, and material, is widely used in Middle Eastern countries. The kamanché described in this article is modeled after the Persian (Iranian) instrument. The kamanché is a very old instrument and possibly dates back as much as 1500–2000 years, being another form of the ancient Indian ravanstron. In 1418 A.D. Ben Abd-ul-Cadir wrote a treatise (the manuscript of which is in the University of Leyden) which shows that its existence today has changed little since that time. A 16th-century Iranian miniature painting in the Khamza of the poet Nizami shows a kamanché very similar to the one described below. Various early European travelers to Iran have described it also. Among these are Sir W. Ouseley in 1819,1 and Sir Percy M. Sykes.2 Sykes describes a kamanché in Khorasan, an eastern province of Iran, as follows: “...made of walnut wood. The total length is 37", with fingerboard 9" in length. The instrument is handled like a violoncello; but in shape resembles a mandolin with a long spike of worked iron. The belly is constructed from a pumpkin covered with parchment and mounted with stripes of bone radiating from a turquoise. The neck is pierced on each side with three holes, and with a hollow at the back, 3" in length; there are three wire strings and six pegs, three of which are dummies. The bow resembles our double-bass bows and is 22" in length; it is made of gypchin wood and has a strap and a loop with which to tighten the horsehair. To complete the equipment, a bit of beeswax is tied on to serve as rosin.” Become A Member to Continue Reading This Article This article is part of our premium web content offered to Guild members.

Posted on July 1, 2022March 5, 2024 by Dale Phillips The Right CAD Curve The Right CAD Curve Bezier Curves, Not Splines, Are Truly Smooth Curves by David Golber Originally published in American Lutherie #72, 2002 and Big Red Book of American Lutherie Volume Six, 2013 Bezier curves, as opposed to splines, have been known since the 1970s. They are supported by AutoCAD and AutoCAD LT, but not by many other popular CAD packages. What are they, and why do we care? It’s easiest to start with an example. Fig. 1 shows the outline of a harpsichord. Look at the curved side. The coordinates of the points are from Kielklaviere,1 which describes the curved side of the instrument by listing the coordinates of points along the side. The curve in Fig. 1 is the ordinary spline through those points. Fig. 2 shows that one of the points is erroneous enough that it clearly makes the curve bumpy.

It’s something like a small mandolin; the scale is 15 1/4". For tuning machines, I’ve been using Schaller M6 minis, but I’ve been modifying them to solve some problems: the peghead is only 3/8" thick, and the threaded bushings that come with the Schallers don’t tighten down this far; the instrument tends to be too heavy at the head; and I have trouble getting enough string angle over the nut. The photos show what I’ve done to the Schallers. The threaded bushings have been shortened; the metal knobs have been replaced by the proverbial Handsome Pearlescent Plastic; and the shafts have been cut down short and reshaped.

Posted on November 19, 2019March 7, 2024 by Dale Phillips What You Should Know About The Hardanger Fiddle What You Should Know About The Hardanger Fiddle by David Golber Previously published in American Lutherie #36, 1993 and The Big Red Book of American Lutherie, Volume Three, 2004 Someone has walked into your shop with yet another weird instrument. This time, it’s sort of like a violin, but it has a whole lot of pegs, the top is carved funny, it has pearl and bone inlay, and it’s decorated with flowery drawings. He says his grandfather brought it from Norway in 1890, and he wants you to put it in playing condition. Well, it’s a Hardanger fiddle (hardingfele in Norwegian). The instrument originated in the area around the Hardanger fjord, whence its name. It is distinctly Norwegian; in fact, it is played in only about a quarter of Norway, the western and south-central areas. The oldest instrument found has a date of 1651. The musical tradition is still very much alive, and continues unbroken up to the present. Beginning in about 1850, there was an absolutely enormous emigration from Norway to America — something like a third of the population. Those who played fiddle of course brought their fiddles with them. In addition there were tours by professional players who performed for their emigrated countrymen and then returned to Norway. But the instrument and the music died out in America. The children of the immigrants rarely learned to play, and father’s fiddle lay in its case in the attic, or was hung on the wall like an icon of a lost era. Now there is something like a revival here in America, not only among the descendants of the immigrants, but also among those not of Norwegian ancestry who have discovered the music.

Posted on January 11, 2010February 7, 2024 by Dale Phillips Letter: Installing Pegheads Letter: Installing Pegheads by David Golber Originally published in American Lutherie #102, 2010 Dear American Lutherie, A couple years ago a customer asked me about installing Pegheds/Knilling Perfection Planetary Pegs in his instrument. I read the instructions, sent by Mr. Herin, for installing them: he said to use Gorilla Glue. Now I get nervous. I’m being told to glue something into a $5000 instrument with Gorilla Glue. Hmm. I wrote to him asking how to remove them. I got no reply. These are mechanical devices. What lifetime do they have? Ten years? Twenty? Thirty? (Thirty years is a good lifetime for industrial products.) Does the manufacturer put a warranty on them? For how long? Will the manufacturer even be in existence thirty years from now?
