How Often to Tune a Piano and Why it is Needed

Like any other musical instrument, pianos require maintenance and tuning to ensure that they are in optimal condition. Besides regular dusting and polishing, tuning the piano is an important maintenance task. How often to tune a piano? Let’s share some information about it.

Tuning a piano is the process of adjusting the tension of its strings to achieve the correct pitch. It requires to have a professional piano technician to perform the tuning.

What Causes a Piano Out of Tune

A piano is a complex instrument that produces sound through the vibration of its strings. To produce a pleasant sound, the piano must be in tune. When it is out of tune, the music played on it can sound dissonant. Here are some of the most common causes of a piano going out of tune:

Changes in Temperature and Humidity

One of the most common causes of a piano going out of tune is changes in temperature and humidity. These factors can cause the strings to expand or contract, which can change their tension and pitch.

When the humidity increases, the soundboard can absorb moisture and expand, putting more pressure on the strings, hence, causing the piano to go sharp. Conversely, when the humidity decreases, the soundboard can contract, loosening the strings and causing the piano to go flat.

To avoid large temperature fluctuations, it is recommended not to put your piano in a direct sunlight spot.

Lack of Maintenance

A lack of maintenance can also cause a piano to go out of tune. Over time, dust and debris can accumulate inside the piano, affecting its internal components. The pins that hold the strings in place can become loose, causing the strings to go flat. Neglecting regular tuning can also contribute to the piano going out of tune, as the strings can continue to stretch over time.

Additionally, there is also natural wear and tear. As the piano ages, the strings can lose their elasticity, causing them to stretch and change pitch. The hammers can also become worn and misshapen, which can affect the tone of the piano.

Moving the Piano

Moving a piano can also affect its pitch. The tension on the strings will change during transportation, causing the piano to go sharp or flat. Moving the piano to a different climate or altitude can also affect its tuning.

How to Tell if a Piano Is Out of Tune

If you own or play the piano regularly, it’s essential to know when it’s out of tune. Usually, it is by ear you hear out-of-tune music. A piano that is out of tune produces discordant sounds and makes playing it less enjoyable.

Here are some signs that help to identify:

The Music Sounds Dissonant

This probably is the most apparent sign that a piano is out of tune. Dissonance or discordant occurs when two or more notes sound together and produce a harsh, unpleasant sound. If you notice that the music you’re playing on the piano sounds off, it’s a good indication that the piano needs to be tuned.

Moreover, if the pitch of the notes played on the piano sounds lower or higher than it should be, it’s a clear indication that the piano needs to be tuned. If you have a good ear for pitch, you can check the tuning of the piano by playing a familiar tune and comparing it to how it should sound.

The Piano’s Strings Look Loose

You can also tell if a piano is out of tune by examining the strings. If the strings look loose or slack, it is a clear indication. When a piano is in tune, the strings should be taut with consistent tension.

How Often to Tune a Piano

Maintaining proper tuning is critical to ensure that your piano sounds its best. However, how often to tune a piano can depend on several factors, including usage, environment, and the piano’s age.

Here are some general guidelines on how often to tune a piano:

New Pianos

New pianos should be tuned four times in the first year of use, regardless of how often they are played. This is because new strings tend to stretch and settle in during the first year of use. Tuning the piano regularly during this period helps ensure that the piano is in tune and sounds its best.

Regular Use

If you play the piano regularly, it’s essential to tune it at least once or twice a year. Regular playing can cause the piano’s strings to stretch, which can affect its tuning. Tuning the piano regularly helps maintain its tuning and ensures its sound quality.


The environment in which the piano is located can also affect its tuning. If the piano is located in an area with significant temperature or humidity changes, you need to tune it more frequently.


As a piano age, its tuning stability can decrease, and it may need to be tuned more frequently. Older pianos may also require additional maintenance, such as replacing worn parts or restringing, to maintain their tuning stability.


When a piano is moved from one building to another, or from one room to another room in the same building or house, the piano should be tuned, but not right after the move. It is best to let the piano sit for three to four weeks in the new location before performing the tuning. This will allow the instrument to be accustomed to the climate of the new location so that the next tuning will be more accurate.


Several factors can cause a piano to go out of tune and usually, there are signs to indicate that a piano is out of tune.

How often to tune a piano depends on several factors, including usage, environment, and age. New pianos should be tuned four times in the first year, while regular use may require tuning once or twice a year. Climate changes, age, and moves also affect the piano’s tuning stability and may require more frequent tuning or additional maintenance.

Furthermore, pianos may suffer from other issues that can affect their playability and overall sound quality. For example, keys may start to stick, or the pedals may become unresponsive. These issues can be caused by a variety of factors, including changes in temperature and humidity, wear and tear, and general use. A professional piano technician can help to identify and fix these issues during the tuning session before they become more significant problems.

For those who play the piano or own one, regular tuning is an essential part of ensuring that the instrument is in good condition and ready to produce beautiful music. It also helps to mitigate the effects of natural wear and tear on the instrument, as well as identify and fix any issues.
