Piano Humidity control is important to protect and maintain your piano. A stable (acoustic) piano is always more enjoyable to play, but for that you need to protect your piano from the extreme or fluctuating humidity levels.Here’s more on how humidity impacts a piano and the various options available to keep your piano in top working condition (maintain proper pitch, and protect the various, tiny wooden parts inside your piano).

Impact of Humidity

Its a known fact that humidity impacts wooden products, and because pianos are made of wood, moisture affects pianos as well.

Seasonal changes in weather and humidity can cause wood to swell and to shrink. In the case of pianos, this phenomenon (of swelling and shrinking) affect three main areas:

  1. Stability of the Tuning
  2. Touch of the Keys and Performance of the Piano
  3. Life of your piano

This is the reason why acoustic pianos need to be protected against changes in weather and humidity.

Too much humidity can cause the following problems in a piano:

  • Keys can stick
  • Pitch could be raised sharp
  • Touch of the keys can feel sluggish.

Lack of humidity on the other hand can impact your piano more adversely.

  • Wood can crack
  • Glue joints can become loose
  • Your piano could fall flat (requiring more frequent tuning)


Watch: Humidity Control for Your Piano. As mentioned, proper humidification helps reduce seasonal pitch changes and allows a more stable, longer lasting tuning.

What Can You Do?

Here are some suggestions that you can incorporate before thinking of buying a humidity control system for your piano (can cost around $500-$600).

  • Get a hygrometer to test your piano’s ambient conditions (available for around $20).
  • If you already own a heating/cooling system that includes humidity control, make sure its in working condition.
  • Excessive dryness can be prevented by using appropriate window coverings (even leafy plants in your room) – or you may buy an in-room humidifier for your piano.
  • Excessive moisture can be prevented by keeping windows closed during cloudy or rainy days and – or you may buy an in-room dehumidifier for your piano.
  • If these methods fail to produce a more stable environment for your piano, you can consider installing a humidity control system for your piano.
