All upright and grand pianos need periodic regulation to perform their best. The frequency of regulation is dependent upon the amount of use, exposure to climatic changes, and the instrument's quality, age, and condition. New pianos may require regulation in their first year because settling and compacting of parts sometimes necessitates adjustment.
How often is regulation needed?
Only you and your technician together should decide how frequently your piano needs regulation. Several factors can contribute to this. The intensity and number of hours your instrument is played and climatic conditions are all determinants. A piano kept in relatively consistent conditions which are neither too wet nor dry, optimally at a temperature of 68 degrees Fahrenheit and 42 percent relative humidity, will require less adjustment.
The quality of the instrument itself also can affect the frequency of regulation. Some manufacturers decrease costs by not going over the regulation and voicing processes in the factory as much as needed. Reputable retailers sometimes do the necessary regulation themselves prior to selling the pianos, but others do not.
Also, performance instruments may require some regulation before each use, due to the higher demands placed on them.
