If you’re a piano owner or player, you’ve likely experienced the frustration of your instrument going out of tune. The beautiful melodies that once filled your home now sound slightly off-key, and you find yourself wondering, “Why does my piano go out of tune?” In this article, we’ll explore the common reasons behind piano tuning issues and what you can do to maintain your piano’s pitch and harmony.


1. Changes in Temperature and Humidity

Pianos are highly sensitive to changes in temperature and humidity. The soundboard, strings, and wooden components expand and contract with variations in environmental conditions. When humidity levels rise, the wood absorbs moisture and swells, causing the strings to tighten and the pitch to rise. Conversely, in dry conditions, the wood contracts, leading to a drop in pitch. These fluctuations can cause your piano to go out of tune.

Solution: To mitigate the effects of temperature and humidity, consider placing a humidifier in the room where your piano is located. Additionally, maintain a stable temperature and humidity level by using a dehumidifier or air conditioner.


2. Frequency of Use

The more frequently you play your piano, the more often it will require tuning. Regular use places stress on the strings, causing them to stretch and change in pitch over time. Professional pianists may need to tune their instruments as often as every few weeks, while casual players may only need to tune their pianos a few times a year.

Solution: Schedule regular piano tuning sessions with a qualified piano technician. They can assess the condition of your piano and adjust it as needed to keep it in tune.


3. Age and Quality of the Piano

Older pianos and lower-quality instruments are more prone to going out of tune. Over time, the components in an older piano can deteriorate, leading to tuning instability. Inexpensive pianos may have lower-quality strings that stretch more easily.

Solution: If you own an older or lower-quality piano, consider investing in regular maintenance and tuning to help extend its lifespan and improve its tuning stability.


4. External Factors

External factors, such as moving the piano, can also cause it to go out of tune. The jostling and shifting during transport can affect the tension of the strings and lead to pitch fluctuations.

Solution: When moving your piano, hire professional piano movers who are experienced in handling and transporting these delicate instruments. After a move, it’s essential to have your piano tuned to restore its proper pitch. You can read more on our piano removal services for professional consultation.


5. Lack of Maintenance

Neglecting regular maintenance can lead to a piano going out of tune more frequently. Dust and dirt can accumulate inside the piano, affecting its components and sound quality. Neglected strings can become rusty and lose their elasticity.

Solution: Keep your piano clean by dusting the keys and inside the piano regularly. Schedule periodic maintenance and tuning appointments with a qualified technician like (AMH Pianos team) to ensure your piano’s longevity and optimal performance.



Summarily, understanding why your piano goes out of tune is the first step towards maintaining its pitch and harmony. Temperature and humidity fluctuations, frequency of use, the piano’s age and quality, external factors, and a lack of maintenance all contribute to tuning issues. By addressing these factors and investing in regular care and professional tuning, you can enjoy the beautiful sound of a well-tuned piano for years to come.
