Piano Tuning — What’s Good to Know
How Often Should a Piano Be Tuned?
Most pianos should be tuned at least once a year. Pianos that are played frequently, used for teaching or performance, or located in changing environments benefit from two tunings per year.
Regular tuning helps your piano sound better, stay stable, and prevents bigger adjustments from being needed later.
Why Do Pianos Go Out of Tune?
Pianos go out of tune naturally over time. The main causes are:
Changes in temperature and humidity
Normal string tension settling
Regular playing
Long periods without tuning
Even pianos that are not played often will slowly drift out of tune.
What is Standard Pitch?
Modern pianos are tuned to concert pitch (A = 440 Hz). If a piano has not been tuned for a long time, it may drop below this standard and require a pitch raise before it can be accurately tuned.
What is a Pitch Raise?
If a piano is significantly flat, it may need a pitch raise, which involves several tuning passes to gently bring the piano back to standard pitch before fine tuning. This is a normal process and helps ensure a stable, long-lasting result.
How Long Does a Tuning Take?
A standard tuning usually takes about 90 minutes. If a pitch raise is required, additional time or tuning passes may be needed. This will always be discussed in advance.
Do New or Recently Moved Pianos Need Tuning?
Yes. New pianos and pianos that have been moved often require tuning after they have settled into their new environment. Changes in humidity and temperature can affect tuning stability.
How Can I Help My Piano Stay in Tune?
You can help by:
Keeping the piano in a stable environment
Avoiding direct sunlight, heaters, and drafts
Maintaining consistent humidity where possible
Scheduling regular tunings
What Happens During a Piano Tuning?
During a tuning, each string is adjusted so the piano is in tune with itself and balanced across the keyboard. A professional tuning improves clarity, harmony, and overall musicality.
