Humidity and Your Instrument

Instrument Care


Our area experiences extreme weather changes from season to season. The extreme humidity in the summer becomes extreme dryness in the winter months. All wooden instruments are affected by the change of season. Wood expands in humid environments and will contract as the environment gets more dry. These varying extremes can result in the separation of seams or the splitting, cracking of your beloved instrument.


First and foremost, you need to know what the humidity is in the room you store your instrument. It’s incredibly important to know what you’re dealing with.  A basic room Hygrometer will work to read the humidity in your room. This is the first line of defense combating your instrument drying out in the winter.

You can also keep a humidifier in your case. Something like the Oasis OH-2 Digital Hygrometer would be perfect.


Protect your Instrument

What instruments need protection?

Electric and acoustic guitars

An example of damage that can be done to your electric guitar is  the fingerboard shrinking to the point of having to re-fret your instrument.)

Violins, violas, cello and bass as well as mandolins and pianos need humidification.

Woodwind instruments such as clarinets, oboes, bass clarinets need to maintain a stable level humidity for the same reason.

A room humidifier is important but may not be enough.                                                                                                                                    

You might need a simple humidifier for inside the instrument. Here are some of the best easiest to use.

Guitar- in instrument humidifier – Grover Guitar Humidifier


Violin- in instrument humidifier – Violin Dampit

These are just 2 examples of humidifiers we carry.

A humidifier kept in the case is helpful as well.

Guitar- in case humidifier – D’Addario Humidipak Two-way humidification System


Pianos require a Damp Chaser. These help combat your instrument dry in the summer and hydrated in the winter.

What not to do:

Do not keep your instrument out anywhere near a wood stove.

Do not leave your instrument overnight in a car if its cold.

Do not leave your instrument in a hot car in the summertime.

Pianos and guitars should be against an interior wall in your house, NOT an exterior wall.
