Does the level of humidity in your home affect your piano?
A large part of your piano is made up of wood and felt. Two natural materials that swell or contract depending on the amount of humidity in the air.
Every time the humidity levels change the materials in the piano will shift. The movements are often small, but it doesn’t take a lot to affect the piano. There are many small parts that make up the piano and work together so if one part is misplaced there are other parts that will feel the change as well.

How can you help your piano from being impacted by these changes?
The placement of your piano in your home is one way in which you can protect your instrument. Placing your piano on a wall not facing the outdoors will keep it at a stable temperature. If possible keep it at a distance from major heat sources such as a wood stove.

Humidifiers designed for the piano are a great way to maintain stability in your piano. Dampp Chaser systems are made specifically for pianos. These systems are installed by a qualified technician and include a humidifier, dehumidifier, and humidistat. Once installed it is maintained by adding water and water treatment to the system when the light indicator notifies you and having the pads replaced as needed. The pads are usually replaced every 6-12 months.

Is a dampp chaser humidifier system worth it?
It is an investment when you initially have it installed but it can help keep your piano in good repair and the tuning stable which at the end of the day can save you money.

What about a regular room humidifier?
The downside of a room humidifier is that the humidity is not directed specifically to the piano. The water will be dispersed throughout the whole room leaving a small amount that impacts the piano. The larger the room, the less impact the humidifier will have on the piano.

The more stable the humidity levels, the more stable your piano will be.
