Tuning

Your piano will receive top-quality tuning from Gardner Piano Services. The first step in the tuning process is determining how far out of tune the piano is. Typically, if the pitch deviates more than 10% from A440—either sharp or flat—a pitch correction is required. This is necessary because a significant change in string tension will cause the piano to quickly fall out of tune again. During pitch correction, it’s important to slightly “overcompensate” so the pitch settles back close to where it should be. Once the pitch correction is completed (if needed), fine tuning begins. A professional tuning software called Pianometer is used. With modern technology, tunings can be completed more efficiently while achieving the same results as traditional aural (by ear) tuning. Pianometer determines the temperament using inharmonicity measurements taken before tuning and stretches the octaves just as they would be adjusted by ear.

Throughout the tuning process, several techniques are used to help the piano hold its tune as long as possible. For instance, because tension exists in multiple areas along each string, it’s important to “set the pin” to release that tension. In simple terms, the string is tuned slightly past the correct pitch and then brought back into tune. Another key method is performing “test blows” during tuning. This involves striking the keys firmly to further release tension. Without this step, tension could be released later during regular playing, causing the piano to slip out of tune.
After fine tuning is complete, each note is carefully checked and refined as needed. Finally, one last test is performed on most pianos: every key is struck with the force of a concert pianist. If any strings shift, they are corrected and the test is repeated. At this point, your piano is fully tuned and ready to be enjoyed.

How Often Should a Piano Be Tuned?
In general, piano manufacturers recommend tuning every six months, though several factors can affect this schedule.
Environment. A piano will hold its tune best in a stable environment. In many regions, including Northwestern Louisiana, winters tend to be dry while summers are more humid. These changes cause the wood inside the piano to shrink and swell, leading to tuning instability. To maintain optimal conditions, keep the room at a consistent temperature and humidity level. It’s also advisable to place the piano against an interior wall, away from windows. A piano moisture control system can also help regulate these conditions.
Usage. Regular playing affects tuning stability as well. Vibrations from the soundboard and repeated hammer strikes cause fluctuations in string tension. As a result, frequently used pianos require more frequent tuning. For example, a home piano may not need tuning as often as one in a church. Instruments in universities or concert venues typically need even more frequent attention.
