Signs You Shouldn’t Ignore
Maintaining an acoustic piano involves more than occasional tuning. Although tuning is the most widely known service, there are other crucial tasks that must be performed to preserve both the instrument’s sound and mechanical precision. Over time, even a piano that is used infrequently can begin to show signs of wear that require professional attention.
Recognising these signs is essential to avoid serious damage, preserve the sound quality, and extend the instrument’s lifespan. In this article, we outline the most common indicators that suggest it’s time to consult a piano technician.
Loss of tuning stability
One of the clearest signs is frequent detuning, particularly if it happens soon after the piano has been tuned. If the instrument loses its pitch after only a few weeks, this may indicate a structural issue or a lack of proper upkeep.
A well-maintained piano should remain in tune for at least six months, except in cases of drastic changes in humidity or temperature. If tuning does not hold, it may be necessary to examine the string tension, tuning pins, or the overall condition of the frame.
Keys that stick or respond unevenly
The touch and response of the keys can reveal a great deal about the instrument’s internal state. If a key sticks, responds slowly, or sounds weaker than the others, this may be a sign of a problem with the piano action.
Dust buildup, worn felts, or deteriorating moving parts can negatively affect responsiveness. Left unresolved, these issues can make the playing experience inconsistent and hinder musical expression.
Unusual noises or creaks while playing
A properly maintained piano should not produce strange sounds when the keys or pedals are used. Creaking, clicking, or odd resonances can indicate internal wear, loose joints, or problems with the damper mechanisms.
While these sounds may seem minor, they often serve as early warnings of deeper structural or mechanical problems that should not be overlooked.
Pedals that don’t function correctly
The sustain, soft, and sostenuto pedals should operate smoothly and predictably. If a pedal sinks too low, sticks, or fails to produce the desired sound effect, there may be an issue with the connecting rod or internal mechanics.
Pedal malfunction not only limits expressivity but can also be a sign of wear in essential internal parts that require servicing.
Changes in sound quality
Over time, a piano’s tone may become dull, uneven, or overly metallic. This can result from worn hammers, dirty strings, changes in the soundboard, or general tension loss.
A qualified technician can diagnose the precise cause and perform necessary adjustments such as voicing, hammer shaping, or internal cleaning to restore tonal quality.
Routine servicing as prevention
Even if no obvious problems are present, regular servicing is strongly recommended, especially for older pianos or those that haven’t been professionally inspected in years. A technician’s visit can correct minor issues before they become serious and ensures all components function harmoniously.
A standard service may include action regulation, felt inspection, interior cleaning, and a general assessment of the instrument’s condition.
Conclusion
Recognising the signs that your piano needs professional servicing is key to preserving its sound, playability, and long-term value. Ignoring small faults can lead to more expensive repairs and negatively affect the playing experience.
