Understanding Humidity and Stringed Instruments
by lastringplayer · February 16 Nike Air Max 180 NZ , 2019


Atmospheric water – humidity – changes the size and weight of wood in violins, cellos and other stringed instruments. But it can be managed.


Perhaps Vivaldi understood both the beauties and curses of nature. Arguably the composer鈥檚 most popular composition, 鈥淭he Four Seasons鈥?(Le Quattro Stagioni), celebrates the changes from spring through summer, fall and winter. But he also might have known how changes in weather can subtly torture fine cellos, violins, basses, and all other wooden-stringed instruments.


That鈥檚 because all of those instruments are forged from an organic product, wood, that is affected by humidity. The violin that plays well outside on a hot, sultry summer night will need care and adjustment if moved inside to a dehumidified space (such as a concert hall) or transported to a dry, cooler climate a day or two later. Humidity changes are the enemy of stringed instruments.


The scientific explanation of this is in equilibrium moisture content (EMC), which is the balance between water bonded within the wood of the instrument itself and water in the air. That moisture in the wood, when newly introduced (e.g., when the violin travels from dry, coastal California by airplane to a humid Georgia in summer), will have several effects on the instrument and how it plays:


Expansion (humid air) and contraction (dry air) of all pieces of wood. The effects of shrunk (when dry) or swollen (when wet) wood: There are many things that can go wrong, which are the symptoms that can alert you to what the problem is. They include: Tightening or loosening of the strings, slippingsticking pegs, open seams or cracks, buzzingnasalmuted sounds, when the bow skates across the strings, a decreased response or projection of sound, or a change in the neck projection.


Weight increases. The sound of a stringed instrument changes because the wood is denser with moisture in humid conditions. What one buys in a violin maker鈥檚 shop does indeed change as soon as it travels somewhere.


The bigger the instrument, the bigger the effects. Because it is made of more wood, a bass or a cello will experience greater effects from changes in humiditymoisture than a violin.


Ideally, you would treat your violin the way museums treat great physical works of art. You would always maintain a set degree of humidity and temperatures. Unfortunately, musical performances and musicians exist in a bigger world; therefore the stringed instruments must find a way to travel to the ends of the earth.


This is why a few active measures by the musician might be undertaken. They include measuring the relative humidity of an environment with a tool called a hygrometer. But just measuring it is step 1. More importantly, you can control humidity by several means: run a humidifier (if it is too dry) or a dehumidifier (if it is too wet) in the space where you will be playing. For traveling, a humidifying Dampit might work (particularly useful in winter, when artificial heating systems are drying). But ideally, the violin will adjust to the local humidity – and the musician will adjust the instrument strings accordingly – when in a new environment for two or three days.


To gain a bit more insight into protecting an instrument from environment, a visit to a local violin shop should do the trick. A local violinmaker would stock proper cases, dampits and humidifiers among the accessories they stock.


Vivaldi may not have had the modern tools for reading humidity, nor did he have airplane travel to hasten the atmospheric changes. But he certainly appreciated the graduations in temperature and humidity over the course of four seasons that allow us to adapt more easily to Nature鈥檚 whims.
