How Long Does a Piano Tuning Take?

A standard tuning takes about 90 minutes. If your piano hasn't been tuned in several years, plan on two to two and a half hours, because it will likely need a pitch raise — a first corrective pass — before the fine tuning. And if anyone offers to tune your piano properly in half an hour, be suspicious rather than impressed.

Here's where the time actually goes.

What happens in those 90 minutes

A piano has around 230 strings for its 88 notes — most notes have two or three strings that must match each other exactly, then sit in precise relationship to every other note on the instrument.

The first few minutes: assessment. The technician plays through the piano, checks how far it sits from A440 concert pitch, and looks for anything that affects the work — a sticking key, a buzz, loose tuning pins. This is also when you'd hear about it if the piano needs more than a standard tuning, before the work starts, not on the invoice.

The bulk of the visit: string by string. Setting the temperament (the reference octave everything else is built from), then working outward through the treble and bass, string by string, testing each against the others. Tuning by ear means constantly listening for the beats between strings and adjusting until they lock in — unhurried, repetitive, precise work. This is the part that cannot be rushed: a tuning pin set hastily doesn't stay put, and the piano drifts within weeks.

The last stretch: checking the whole. Playing intervals, octaves and chords across the full keyboard to confirm the piano agrees with itself, plus a quick once-over of the action. Then you get to hear it.

When it takes longer than 90 minutes

A pitch raise adds roughly an hour. A piano more than about 20 cents below pitch can't be pulled up in one pass — raising the tension of 230 strings adds significant load to the frame, and the first strings tuned sag as the rest come up. The fix is a pitch raise: a quicker, deliberate first pass to get the whole instrument near pitch, then a full fine tuning on top. Total visit: usually two to two and a half hours.

Repairs add whatever they add. Small fixes — easing a sticky key, tightening a pedal — are often minutes and handled during the same visit. Anything bigger gets discussed and priced first.

First tunings on new or newly moved pianos sometimes run slightly long, since fresh strings and new environments mean more settling to chase.

The 30-minute "tuning": why fast is a red flag

Occasionally someone advertises very fast, very cheap tunings. Physics doesn't negotiate: you cannot properly set 230 strings, by ear, with stable pin positions, in 30 minutes. A rush job can sound acceptable when the technician leaves and be audibly off within a month, which makes it the most expensive kind of cheap. When comparing quotes, ask how long the visit takes — it's one of the most revealing questions you can ask. (More on pricing in our guide to what piano tuning costs in Toronto.)

How to plan for the visit

You don't need to do much: reasonable quiet helps (a technician tuning by ear is listening for tiny wavers under the notes, so this isn't the hour for the dishwasher and the vacuum), decent light near the piano, and clear access to the instrument — lid, music desk, and the top of an upright free of frames and plants. Kids and pets are welcome spectators within reason; many of our favourite visits involve a six-year-old supervising closely.

You don't need to stay glued to the room, either. Most clients get on with their day and come back for the best part: hearing the piano land back at true pitch.

Common questions

Can a piano be tuned in 30 minutes?
Not properly. With ~230 strings to set and stabilize by ear, a real tuning takes about 90 minutes. Significantly faster means corners cut — usually pin-setting, which is exactly what determines whether the tuning lasts.

How long does a tuning take if the piano hasn't been tuned in 10 years?
Plan for two to two and a half hours. It will almost certainly need a pitch raise pass before the fine tuning. The result is worth the extra hour.

How long after a tuning until I can play?
Immediately. Play it the moment the technician stands up — in fact, please do. The 30-day guarantee exists precisely so that if anything sounds off once you've lived with it, we come back free.
