Five Signs Your Piano Is Ready for a Tuning
Familiar songs sound subtly wrong, octaves that should match sound like two pitches fighting, the tone turns jangly or “honky-tonk,” it's been more than a year, or the piano was recently moved or its room's climate changed. A piano that's gone flat is almost always still tunable.
You don't need a trained ear to know your piano needs attention. Most pianos tell you, if you know what to listen and feel for. Here are the five most common signs.
1. Familiar songs sound subtly wrong
The clearest tell. A piece you know by heart starts to feel sour or "off," even though you're playing the right keys. That's the intervals between notes drifting out of agreement.
2. Two notes that should match don't
Play an octave — the same note low and high. It should sound clean and unified. If it sounds like two pitches fighting each other, or shimmers in a way it didn't used to, the piano has drifted.
3. It sounds jangly or "honky-tonk"
Many notes on a piano use two or three strings struck together. When those strings fall out of agreement with each other, you get that detuned, saloon-piano warble — a sign it's been a while.
4. It's been more than a year
Even if nothing sounds obviously wrong, the calendar is a sign in itself. Pitch drifts slowly enough that your ear adjusts; a piano can be noticeably flat before you consciously notice.
5. It was recently moved, or the room's climate changed
A move, a new home, a renovation, switching the heat on for winter — any big change in environment can knock a piano out of tune within weeks.
One reassuring note: a piano that's gone flat is almost always tunable. It may need a pitch raise first, but "out of tune" rarely means "ruined."
Common questions
How do I know if my piano needs tuning?
Play a single note in the middle of the keyboard and listen for a waver inside it — as if two slightly different pitches are sounding at once. That, sour-sounding chords, or a piano that clashes with recordings all mean it's due. If it's been more than a year, it's due regardless.
Can a piano need tuning even if nobody plays it?
Yes. Pianos drift because humidity moves the soundboard, not because of playing, so an unplayed piano goes out of tune just as fast — nobody hears it.
What happens if I wait too long to tune it?
The piano sags further below pitch and will need a pitch raise before a normal tuning holds, which takes longer and costs more. Small problems like sticky keys also go unnoticed and grow.
