How Humidity Affects Piano Performance – Protecting Your Instrument Year-Round

The Hidden Enemy of Piano Stability

Your piano is more sensitive to weather than you might think. Fluctuating humidity levels cause the wooden soundboard, keys, and action parts to expand or contract — directly affecting tuning, tone, and long-term durability. In Edmonton’s dry winters and humid summers, these changes can have a major impact on your piano’s performance.

At STRAND Piano Repairs & Tuning, we’ve seen firsthand how inconsistent humidity can transform a perfectly tuned instrument into one that sounds lifeless or unstable within weeks.

What Humidity Does to Your Piano

• Dry air (below 35%) shrinks wooden parts, loosens tuning pins, and can cause soundboard cracks.

• Excess moisture (above 55%) swells felt and wood, leading to sticky keys, sluggish response, and muffled tone.

• Rapid swings between humid and dry environments cause the most damage — stressing the frame and joints over time.

Even small variations can throw your piano out of tune or cause mechanical wear that shortens its lifespan.

How to Protect Your Piano

• Maintain indoor humidity between 42–45%.

• Use a humidifier or dehumidifier depending on the season.

• Install a piano climate control system like the Dampp-Chaser Piano Life Saver, professionally fitted by STRAND.

• Schedule seasonal tunings to keep pitch and tone consistent.
