Most piano owners call for a tuning when something feels “off.” But not every problem is a tuning problem — and if you keep booking tunings for an issue that’s actually mechanical, you’ll pay for the same visit twice without ever fixing what’s wrong. Here are five signs your instrument needs more than a tuning, and what’s actually happening underneath.
1. Sticky or Slow-Returning Keys
If a key hesitates before it comes back up, sticks down entirely, or feels different from its neighbors, that’s not pitch — that’s mechanics. Chicago’s swing between bone-dry winters and humid summers causes wood and felt components in the action to swell and contract, which can bind key bushings or cause friction points along the key bed.
A tuning won’t touch this. It needs a technician to inspect the key bushings, the balance rail, and the front rail pins, and free up whatever’s binding. Left alone, sticky keys tend to get worse, not better, especially as seasonal humidity shifts continue.
2. Buzzing, Rattling, or Unexplained Noise
A clear, unwanted buzz when you play certain notes — especially if it shows up on just one or two keys — is almost never a tuning issue. It’s usually a loose screw, a rattling music desk, a case part vibrating in sympathy, or a string touching another part it shouldn’t.
These noises can be maddening because they’re often intermittent, appearing more on some notes or dynamics than others. Diagnosing them takes a trained ear and hands-on inspection — a technician will play through the range, isolate the note, and track the vibration to its source rather than guessing.
3. Uneven Key Depth or Touch
Run your fingers across the keys with your eyes closed. If some keys sit noticeably higher or lower than others, or a section of the keyboard feels heavier or lighter to press than the rest, you’re dealing with a regulation issue, not a tuning issue.
Regulation is the process of adjusting the hundreds of precise mechanical relationships in the action — key height, key dip, hammer blow distance, let-off — so that every key responds identically. Instruments naturally fall out of regulation over years of play as felt compresses and wood settles. It’s especially common in pianos that get heavy daily use, like teaching studios and family homes with active students.
Uneven touch isn’t just uncomfortable — it actively works against a developing pianist, making passages harder to control than they should be.
4. Sluggish or Unresponsive Action
If notes don’t repeat quickly when you play the same key rapidly, if the keys feel “mushy” instead of springy, or if soft playing doesn’t produce a clean tone, the action itself needs attention — most likely regulation, and possibly hammer or wippen assembly work if it’s more advanced.
This is one of the most common complaints we hear from serious players and teachers in Chicago, and it’s also one of the most misunderstood — many owners assume a sluggish feel means the piano is simply old or “past its best,” when in most cases it’s a mechanical adjustment away from playing the way it did when it was new.
5. Tuning That Won’t Hold
If your piano sounds noticeably out of tune again within just a few weeks of a professional tuning, that’s a signal worth taking seriously. It can point to loose tuning pins, a pinblock that’s lost its grip, or in some cases structural issues with the soundboard or bridge.
This is different from the normal, gradual drift every piano experiences between tunings. A piano that won’t hold a tuning needs a full diagnostic assessment — tuning it again and again treats the symptom, not the cause, and can end up costing more over time than solving the underlying problem once.
What To Do Next
None of these issues are urgent emergencies, but none of them get better with time either. The earlier a qualified technician sees the problem, the simpler — and less costly — the fix usually is.
At Floating Piano Factory, every appointment starts with a full assessment of your instrument’s tuning, touch, and mechanical condition, not just a pitch check. If something needs regulation, voicing, or action work beyond a standard tuning, we’ll tell you exactly what we find and what it takes to correct it — no guessing, no upselling you on work you don’t need.
If any of the above sounds familiar, it’s worth having your piano properly evaluated. Schedule a visit with our Chicago team and get a clear, honest read on what your instrument actually needs.
