Tech Tip: Care and Maintenance of Orchestral Stringed Instruments

Posted on .

Critical advice about how to keep your violin, viola, cello or bass in excellent condition while maintaining its playability

String Family of Instruments

By following a basic program of care and light maintenance, you can expect to get many years of use from your stringed instrument. Here are some guidelines that will help avoid costly repairs:

1. Never let the instrument get very hot or very cold. Excessive heat can irreparably damage to the varnish and cause the natural adhesive holding the instrument together to melt. Excessive cold and/or dryness (as well as rapid climatic changes) can cause severe cracks which are costly to repair. A good way to judge whether it is safe to leave the instrument in a particular environment is to ask yourself if you would be comfortable being in the same place as the instrument for the same amount of time. If you would be at all uncomfortable, do not leave the instrument in that environment. One of the more common mistakes is leaving an instrument inside a vehicle parked outside. In the sun, the inside of a car can easily reach temperatures over 120 degrees in just 5 to 10 minutes...absolute murder to the instrument.

2. Keep the instrument and bow in the case or bag when not in use. Instruments and bows left sitting out can be sat upon or tripped over. (It happens more often than you think!) When unpacking a cello or bass from its storage bag, always remove the bow from its pouch first and set it aside. Taking the instrument out first leaves the bow vulnerable to breakage when the bag is dropped to the floor. Reverse the process when packing the instrument up, putting the bow away last.

3. Cleanliness is next to godliness. After each playing, use a soft cloth to gently remove all rosin residue from the instrument (top plate, fingerboard, and bridge) and the stick of the bow. If rosin is left on the instrument, over time it will stick to the varnish and become very difficult to remove. There are commercial rosin remover kits available, but even the best of these can harm some instrument finishes. It is best to avoid the problem altogether. A positive side effect of always cleaning off your instrument after each use is that you will only rarely have to polish the body to keep it looking good.

4. Do not overtighten the bow. The stick of the bow is supposed to be curved toward the hair at all times. Under no circumstances should the bow be tightened so much that the curve of the bow stick disappears, or curves away from the hair. This can permanently damage the bow and make it unplayable. Always loosen the bow hair tension after playing and for storage. Avoid loosening the hair so much that the hairs hang limply. You only need to relax the tension off the stick. If a bow is left under playing tension during storage eventually the bow stick will lose its "spring" and will not be able to maintain the hair at a playable tension. If this happens, it often means the bow is ruined. A skilled bow repair technician or luthier can "re-spring" a high quality pernambuco bow, but the process is delicate and costly, and the bow is usually never quite the same again.

5. Avoid handling the bow hair directly with your fingers. Natural oil from your hands will transfer to the hair and shorten its useful life. Also, avoid using too much rosin. Once new bow hair has been rosined thoroughly, just a few strokes of rosin is sufficient before each playing session (often even less). Bass players face the greatest risk of over rosining, as most bass rosins require far less to be applied than for other instrument bows. A common symptom of too much rosin is a "raspy" sound that may even sound like a buzzing string.

6. Keep in mind that the only thing holding the bridge to the instrument is the tension of the strings. Under no circumstances should the bridge ever be glued to the top plate of the instrument. It should be positioned so that the side of the bridge facing the tailpiece is at a 90 degree angle to the top of the instrument. When in any doubt about any bridge or instrument adjustment, it is always best to err on the side of caution and not attempt to make any adjustments yourself. Your teacher or professional instrument specialist can usually make small bridge adjustments safely, quickly and easily.

7. **Very Important** Always refer any repair needs (no matter how minor they may seem) to a qualified instrument repair technician or luthier. Many times a well meaning family member (including one who may be quite skilled with tools and woodworking) has ended up causing a much more extensive (and expensive) professional repair to be necessary after trying a home repair. Often what may seem to be a "horrible calamity" (like an instrument neck coming off, or a big seam opening up between pieces of wood in the body) is something that can be handled rather easily and somewhat inexpensively by an experienced stringed instrument repair technician. Stringed instruments and their components are made out of very special kinds of wood and are held together with very special types of glue (not available at any home improvement store). These types of instruments are designed and built to avoid the worst kinds of repair needs (like actual cracks in the wood).

Routine Maintenance

Several elements of your instrument will require routine maintenance or replacement:

The hair of the bow will need to be replaced regularly. If you are unsure of the service interval, your teacher can recommend the best time for replacement. For most students, the hair should be replaced at least every six months to a year. Extremely heavy use will require more frequent replacement.

Do not wait until strings break to install new strings. Over time, any brand of string will gradually lose its tone quality and lively response, but these changes often happen so slowly that the player may not notice right away. It is especially important for bass players to establish a regular schedule to replace strings, as many times bass strings just never break (unless abused); rather, they just become more and more "dead." To assure evenness of response and tone, it is usually best to replace an entire set of strings instead of mixing new with old single strings on the instrument. When you change strings, save the most recent older set to use in an emergency. Placing the package the new strings came in with the date they were installed in your bag or case will be an easy way to keep track of their age and brand. The time interval for changing strings varies depending on the type of string used, playing style, and simply how long the strings are played. If you are unsure as to how long to wait before changing strings, check with your teacher or consult an instrument specialist at your dealer for advice.

D'Addario Helicore Strings

If you are changing solid steel core student strings on your instrument, it is strongly recommended that you upgrade to high-quality stranded steel core strings like D’Addario Helicore for several reasons. A stranded core string will be MUCH easier to play due to its greater pliability and flexibility, it will be more responsive to the bow, and it will possess very good durability. Also, if you play multiple styles (classical, jazz, blues, bluegrass, etc.), you will find a Helicore variety available to suit your style: Helicore Orchestral with the best bow response and warmest sound, Helicore Pizzicato with brighter tone and great sustain, and Helicore Hybrid as an ideal solution for "crossover" players performing in multiple styles using both arco and pizzicato.

Understand that the instrument storage case or bag is designed to protect your instrument, and it will accumulate some wear and tear through normal use. Case handles, straps, latches, and zippers and should be repaired or replaced when necessary. However, after some time (usually several years), it will probably be necessary to replace the case or bag. If the case has taken a beating, but the instrument has generally remained undamaged while inside the case, then it has served you well. A badly damaged case or bag will not continue to effectively protect the instrument.

The bridge will usually need to be replaced within several years of purchase. A great deal of pressure is placed on the bridge when the instrument is under tension, and often the bridge will start to bend or warp. A warped bridge should always be replaced by a qualified repair technician. Note that if you move to a place with a different climate, a new bridge is almost absolutely necessary as climate changes usually cause the wood of the whole instrument to change just a bit, necessitating a new set-up and adjustment. In certain parts of the country, seasonal climate changes may make it necessary for you to have two or three different bridges to switch out as necessary due to natural changes within the instrument when the humidity changes.

A humidifier when used correctly can help protect your instrument in climates with very low humidity. To learn more, read our Keeping Your Stringed Instruments Healthy with a Humidifier.

Finally, it is always a good idea to take your instrument to a repair technician or luthier at least every few years just to have it checked out and readjusted if necessary (not unlike getting your car tuned up). You will get the most enjoyment (and best performance) out of your instrument if it is kept in top condition.
