Tuning and Regulation -
When a new or used piano is delivered, it will require some time to acclimate properly to the temperature and humidity in your home. During the first year, it is recommended to tune the instrument 3 to 4 times, essentially each season change. Along with tuning, the regulation should be checked and adjusted as needed. This schedule will enable the piano to stay in tune longer. After the first year, 2 tunings a year and 1 regulation are recommend.
Regulation is necessary as over time the pianos geometry changes, springs relax, felts compress and wear on action components. Regulation optimizes the feel and touch of your piano.
Proper Location For Pianos -
The proper location for your piano is very important. Environmental conditions affect tone, tuning and the finish. It is mostly recommend placing your piano on or near an inside wall. Placing your piano near or on a outside wall that is not well insulated can subject it to extreme temperature and humidity changes. Do not place your piano neat a heat source, such as a heat and air register, fireplace or radiator. Keep your piano away from a window or doorway that will be opened often to the outside. This will prevent sudden temperature change. Avoid direct sunlight to wood finished pianos as this can cause a "bleaching" effect and fade the finish.
Temperature and Humidity -
It is suggested you maintain your temperature between 60 & 80 degrees, and the humidity between 40 to 60 percent. During dry winters a room humidifier may be sufficient to add proper moisture to raise the humidity level, whole house humidifiers may be required and are often not that much more expensive.
Try and avoid sudden changes in temperature or humidity. These types changes will affect the moisture content of all the wooden parts, causing them to shrink or swell. This can cause the finish to chip or crack, the string tension to change, sluggish key and action parts.
