Help! My kid’s violin just exploded–is it his fault? How serious is it? My grandfather’s violin has a label inside that says “Antonius Stradivarius, cremonensis faciebat 1720, made in Germany.” Can we sell it and get a house in Montecito? I was in the wings at the Lobero waiting to go on stage for my solo when my bow fell apart. What do I do now? In over 20 years as a practicing maker and restorer of classical bowed instruments in Santa Barbara, these are but a few of the questions that are asked almost daily and are routine in the course of my work. To the musician, focused on the performance, musical instrument repair events can be stressful and disorienting. In this article, I will attempt to demystify some of the health issues associated with the violin family.
Let’s take the label first. Most makers will thoroughly assess an instrument and form their own opinion regarding origin, maker and condition before peering through the sound hole into the dark recesses of the instrument to find the label and see if they agree with it. If the label says Stradivarius, Guarnerius, or Amati, the chances are almost nil that the instrument is from that maker. The great body of this type of work was mass-produced in Germany for early mail order catalogue sales in the early 20th century. The name on the label generally indicated the pattern which was used for the copy and the customers could assure themselves that they got what they paid for by looking into the sound hole. The value of these instruments today is largely based on issues of condition. They often cost more to repair than they are worth. In good condition, they can make wonderful student instruments in a reasonable price range. However, not worth much in trade for the house in Montecito…
If you are a player, you might take your instrument now and inspect it while you read this article. The exploding violin effect is usually caused by failure of the tail gut. This is the strand that loops around the end button, goes over the saddle (the little black ebony piece on the bottom of the body) and is connected to the tailpiece, the part that holds the strings. The tail gut traditionally is made of gut and can deteriorate and break with time. When it breaks, it makes a loud noise and everything suddenly flies off the violin. It’s traumatic, looks expensive, the kid is crying and saying it’s not their fault, you get the picture… The repair is easy and inexpensive. One of the greatest improvements to the violin since Stradivari is the adjustable synthetic tail gut. These virtually never fail and I routinely replace the old-fashioned gut with synthetic. If yours is black and shiny, you are probably good to go.
Sorry about the bow popping apart before the show. They actually are supposed to do that. If the wooden wedges that hold the hair in place are glued in, it requires carving to remove them and the bow may be unnecessarily damaged. Properly, the wedges are not glued and can occasionally fail, particularly in cases where the pockets are damaged by previous repair. Having a quality second bow that you like as much as your first bow is essential in this case, since the quickie loaner might be a dog and seriously hamper the joy of your performance.
A general visual health inspection of your instrument should be a part of the routine of playing. The bridge should be reasonably upright. otherwise, with time, it will bend and be more likely to fall and should be replaced. Inspect the instrument for cracks. Don’t forget to look under the tailpiece and fingerboard where it hangs over the body. You might even lightly tap around the edges of the top and back with a knuckle to discover open places in the body. You might find a flank of the back flapping open that you never noticed before. Which brings us to the next subject.
Violins cannot be repaired through the sound hole, like guitars, so the violin must be dismantled for more serious repair. This is why hide glue is still the only choice. Made from animal hides and bones and thoroughly time-tested over 500 years of violin making, this glue still holds original joinery together on instruments made in the 16th century. Yet when put under pressure, it easily allows the joint to be opened during repair with minimal impact on the instrument itself. When humidity changes occur, the plates of the top and back can shrink, causing a crack. In most cases, the hide glue joint will fail and the instrument will open instead of cracking, and cause a distressing rattling sound while being played. This is a routine scenario in old violins, and the instrument is not broken. It’s the safety valve of the hide glue at work. A short visit with your trusted violin repair person will fix the problem and the instrument may sound better afterward, since tension in the structure is also relieved in the process.
In this article, I’ve attempted to illuminate the most common minor emergencies and help alleviate any worries the player might experience. In a future issue, we’ll delve into the more serious types of damage, which can affect tone, playability and your wallet.
