HOW OFTEN TO TUNE PIANO?
From the moment a piano tuner is finished tuning, little by little the piano starts to go out of tune, imperceptibly at first yes, but steadily and gradually. Pianos that are played more often with heavier pounding will probably need tuning more often. With lighter more incidental playing you can go longer. Most of the time you’ll hear people say that once a year is adequate and that’s probably true. The great Horowitz had his piano tuned on the first Tuesday of each month at 11:00 AM! What makes the difference is how ‘in tune’ you need it, and how ‘out of tune’ you hear it.
