Lack of humidity control can wreak havoc on your piano. Eventually, piano humidity swings can create an instrument that is no longer considered tunable.
The amount of water in your home's wood varies greatly depending on the relative humidity (RH) level of your indoor air. If RH is too low, your indoor air will absorb water from the wood, causing it to shrink. If RH is too high, the wood will take on moisture, causing it to swell.
This is why maintaining an optimum relative humidity level is important. Industry experts recommend keeping your home between 30-60% for proper piano humidity and preservation.
Too much humidity in your home can cause:
- Swollen wood framing around doors and windows
- Warping or rotting wood floors, trim and wood furniture
- Mold and mildew infesting wood furniture
Too little humidity in your home can cause:
- Cracking woodwork and wood floors
- Loose or failing joints on wood furniture
- Your piano and other musical instruments falling out of tune
"Seasonal and even daily changes in humidity cause wood parts to swell and shrink, affecting tuning stability and touch. Extreme swings in humidity can eventually cause wood to crack and glue joints to fail...Maintaining the correct environment will preserve your piano investment for a lifetime of enjoyment." - Piano Technicians Guild
