The approximately 200 strings on your piano exert about 40,000 lbs. of tension on the plate and frame, and about 600 lbs. of down bearing on the bridges and soundboard. Seasonal changes in the humidity as well as the continual decrease of static tension (bending strings), causes pianos to go out of tune.

Depending upon where you live, the degree of humidity change from season to season, the quality and condition of your piano, and how heavily the instrument is played, your piano may need tuning two to four (or more) times per year.During an initial service call, I check and tighten the plate bolts, pin block bolts (and rim bolts in grand pianos), check and space strings as needed, inspect your piano for necessary repairs and adjustments, and tune your piano to A-440 standard pitch.

If your piano is not reasonably close to standard pitch to begin with, it will require a pitch correction. Usually an instrument that is tuned at least annually will not require the additional pitch-correction service. However, some instruments in some environments may need pitch corrections if they do not receive service at least every 4 to 6 months. These situations are not the norm, but they do occur. Every situation is unique, however, from piano to piano and home to home.
