dry air
Guitars and other wooden musical instruments can crack when exposed to dry air. There for it’s important to keep track on the humidity of the air.
Humidity is the proportion of water vapor in the air. There are two kinds of humidity, absolute humidity and relative humidity.
The absolute humidity is a measurement for the maximal possible content of water vapor in the air. It is given in grams per cubic meter (g/m3). This value depends on the temperature of the air. Warm air can absorb more moisture than cold.
The relative humidity (rF) is the ratio of water vapor content to the maximal possiblewater vapor content. The relative moisture is given as a percentage on a hygrometer.
Keep the relative humidity in between 50% and 60%. If it needs to be raised a good quality humidifier is most effective. I use the Venta and I am very content with it.
