The average piano has over 40,000 pounds or 20 tons of tension on a cast-iron plate when at standard A-440 pitch. When a new piano first leaves the factory, each of the approximate 200-230 piano strings has between 180-200 pounds of torsional tension pulling on and pressing against specific parts of the framework designed and scaled precisely for that specific piano. As a result, the piano strings are constantly in a state of decreasing tension in varying degrees due to relative humidity (RH) and temperature changes. The piano quality, condition, age, usage, and location humidity/temperature consistency largely determine the periods between maintenance piano tuning. To help maintain the integrity of the wooden piano parts (bridges, piano tuning pin block, soundboard, and piano action parts) subject to moisture/temperature and/or torsional tension effects, piano manufacturers recommend piano tuning twice a year for students and active pianists and at least once a year otherwise.


    Pianos that have not received a piano tuning in the previous 12 months or are subject to significant relative humidity/temperature swings may have dropped in pitch too much to be brought back to standard pitch in one piano tuning. When the pitch of a piano string is first increased, it will settle back by 10-35% in less than 10 minutes, thus lowering the overall pitch of that specific string leaving it flat of its desired final piano tuning pitch. A pitch raise is necessary to increase the pitch by a precisely calculated amount that provides a predetermined drop bringing the pitch close enough to A-440 so on a second piano tuning, it can be optimally fine-tuned.

    Pianos with humidity control systems require fewer tunings, less repairs, perform better, and last longer. Piano humidity control systems are installed inside the piano to stabilize the Relative Humidity (RH) at 45% to extend the life of the piano and help increase tuning stability. As the (RH) % rises the pitch pulls sharp. As the (RH) % decreases, the pitch falls flat. (RH) stabilized at 45% significantly reduces pitch fluctuations increasing tuning stability and extending the life of the tuning and piano considerably.
