Typically, you should tune your piano at least once a year. However, if you play frequently or have moved your piano, more regular tuning may be necessary to maintain proper pitch.

Pianos go out of tune mainly due to changes in temperature and humidity. As the wood and strings expand and contract, the tension changes, causing the pitch to shift—even if the piano isn’t played.

A standard tuning usually takes 60–90 minutes, depending on the piano’s condition and how far out of tune it is.

Yes. Even pianos that are rarely or never played will go out of tune over time due to environmental changes.

During a piano tuning, a technician brings each string to the correct pitch by carefully adjusting the tuning pins, starting from a reference note and balancing the piano so it sounds good in all keys. Most notes have two or three strings that must be matched perfectly, and the tuner works across the entire keyboard to ensure consistency and stability. The process typically takes about one to one and a half hours and results in a piano that sounds clear, balanced, and in tune.
