Tuning, Regulation, and Voicing: What's the Difference (and Which Does Your Piano Need)?

If you've called around about piano service and heard terms like "regulation" or "voicing" tossed around alongside "tuning," you're not alone in wondering whether these are three different services or just three names for the same thing. They're actually three distinct parts of piano maintenance, and understanding the difference can help you figure out what your piano actually needs before you book an appointment.

Tuning: Getting the Pitch Right

Tuning is the one most people are familiar with. It's the process of adjusting the tension of each string so that every note matches its correct pitch and the piano is in tune with itself. Temperature and humidity changes cause the soundboard to expand and contract throughout the year, which pulls strings out of tune even if nobody's touched the piano. That's why regular tuning isn't a one-time fix — it's ongoing maintenance, generally recommended once or twice a year depending on how much the piano is played and how stable the climate is in the room it's kept in.

Here in Windham and Tolland County, our New England humidity swings between seasons make this especially relevant. A piano that was perfectly in tune in July can drift noticeably by the time winter heating dries out the air.

At Bear Hill Piano, a standard tuning includes a two-pass approach: the first pass brings the piano roughly to pitch, and the second is the fine tuning. This means there's no separate "pitch raise" fee tacked on if your piano has drifted significantly — it's built into the standard $150 tuning.

You can book an appointment online for this if you’re looking for a tuning.

Regulation: Getting the Touch and Response Right

Where tuning is about pitch, regulation is about mechanics.

I often say that a piano is more like a car than a violin. This sounds crazy! A violin is an instrument and a car is a machine.

But hear me out.

A piano has thousands of moving parts in its action — the mechanism that connects each key you press to the hammer that strikes the string.

Over time, felt compresses, wood swells and shrinks, and connections loosen, which changes how the keys feel and respond even though the piano might still be technically in tune.

Even gravity plays a role in everything settling further away from the strings than they were set at the factory.

This is just like a car with its thousands of parts that wear out or rust or just need general tweaking every few years to operate well. A violin has none of those parts and so it doesn’t need the regular maintenance of a piano.

Signs a piano needs regulation include keys that feel uneven from note to note, keys that don't return properly after being pressed, notes that repeat sluggishly, or a general sense that the touch has gotten heavier or lighter than it used to be.

Think of tuning as the oil change. This is something that should be on the calendar every year no matter what. Regulation is what needs to be done every few years as parts wear and settle. It’s like a new pair of tires or brake pads for the car.

Just like car maintenance, it’s much better to make regulation a routine to catch problems before they are actual problems.

Minor regulation adjustments (under 15 minutes of work) can often be handled during a tuning appointment at no extra charge. More involved regulation work is billed at $80/hour in half-hour increments.

It's typically only needed every few years, though pianos that get played heavily, or that are exposed to bigger humidity swings, may need it more often.

Voicing: Getting the Tone Right

Voicing is the least understood of the three, but it's what shapes the actual character of the sound. Every note is struck by a felt-covered hammer, and the density and shape of that felt determines whether the tone comes out bright and percussive or warm and mellow.

Over years of playing, hammers compress and harden in the spots that strike the strings, which often makes an older piano sound harsher or more clangy than it used to.

Voicing adjusts the hammer felt to bring the tone back to where you want it — whether that means softening a piano that's gotten too bright and brittle-sounding, or brightening one that's become dull and lifeless.

Voicing is the most subtle and experience-driven parts of piano work. I’ve studied sound acoustics and understand how the amplitude of overtone waves affects the tone.

I’ve done hundreds of experiments on piano hammers to test different needling and hardening techniques and get the tone to match exactly what you’re looking for.

Which One Does Your Piano Need?

If you're not sure, that's fine — it's part of what a good tuning appointment should sort out. Every tuning includes a free inspection, and I'll let you know honestly if I notice signs that regulation or voicing would make a real difference, without pushing services you don't need.

My goal is always to fix what actually needs fixing, not to run up the bill.

If your piano hasn't been looked at in a while, or if something about how it feels or sounds has been bothering you, feel free to reach out or book an appointment online.

I serve Chaplin, Willimantic, Coventry, Storrs, Windham, and surrounding towns throughout Windham and Tolland County, and I'm always happy to talk through what your piano might need before you commit to anything.
