Hello everyone!

I have a question and I'm hoping someone will be able to understand what I'm trying to say.

I've recently noticed when playing quietly, noises coming from inside the piano; almost like something is "turning" in there. I'm wondering..........is something wearing out and needs to be replaced? Any advise would be most appreciated! Thanks........Larry

Hi Larry: I'm afraid one would have to know a lot more information before hazarding a guess as to the source of the noise in your piano. Vertical or Grand? Is the noise only on certain notes? Can you give a better description of the noise? "Turning" is hard to decipher. Hi pitched or low? You may finally have to have someone at the piano with you to create the noise while you look for it. Hope this helps.....PNO2NER

Hi PNOZNER,

Thanks for responding to my post. I have a 1979 Yamaha U3. When I first start to play, I will occasionally hear the noise, but the longer I play, the more frequent the noise becomes (for obvious reasons, I only hear this when playing pianissimo). As for the noise, I can best compare it to a "motorized sound;" it's as if "gears" are turning;something you might hear while listening to a vintage music box after you've wound it up and it starts to play! I'm not sure what sense, if any, this makes, but this is what I'm hearing. Thanks....Larry

Hi again Larry: What a unique sound you describe! But there has to be an answer. First of all, you have a high quality piano of relatively recent manufacture, however anything is possible. Try first opening up the piano, lift the lid, remove the bottom panel, and see if the noise is still there. Sometimes noises come from the cabinet. If it is still there, pull the piano away from the wall and see if it is any louder in the back. Many noises are centered around the soundboard. I have found items dropped down the back of the instrument and resting against the soundboard resonating when certain notes are played. If these methods don't work, have someone play the piano while you poke around listening in various places. It is sometimes helpful to use a listening tube consisting of a 1" diameter flexible hose (plastic or rubber) held against your ear and used as a stethescope to pinpoint the origin of the sound. In fact, if you know a doctor or nurse, maybe one of theirs would be helpful. Auto supply stores also sell them with long probes to isolate noise sources in cars. If all else fails, you may try calling a piano technician in to help find the culprit. I suspect this will be a problem in diagnosis rather than cure. In other words, finding the problem will be more time consuming than fixing it. Let me know what you finally come up with. PNO2NER

Hi PNO2NER,

Believe I may have located the culprit! After a little experimenting, I just realized I hear this "noise" only when I depress the loud/sustain pedal which, incidentally, is squeaking (loudly) every time it is being depressed. I'm wondering, do I get out the oil can? (The next scheduled tuning is in May--that seems to be a rather longtime to listen to two melodies(?) simultaneously). Thanks again, ....Larry

lawrai, try liquid graphite. If I am not mistaken, oil attracts dirt and is not good for wooden parts. Double check with a tech first, as they may not recommend liquid graphite, but I am fairly certain they do not recommend oil.

Hi Larry: Sounds like you're on the right track. Shadorunnr is correct, oil is not the lubricant of choice. My recommendation would be a silicone or better yet, a teflon lubricant. These are compatible with wood and are available in spray cans. Use sparingly as any lube in the wrong place can create havoc inside a piano. The noise may return, but at least you will know the source and a permanent repair can be made later by a technician. PNO2NER

Hi, a squeaking pedal is the most annoying unwanted noise a piano can make and there are so many causes. Try a couple of these observations - is the pedal rubbing on the piano? Are all screws secure? Is the bolt that connects the pedal to the rocker metal on metal or metal on wood? Are the two rockers touching? Is the vertical rod correctly positioned? Has the vertical rod worn away any felt or leather? Finally a heavy foot can cause the bottom to become pliable so that when the pedal is pressed the bottom moves and creates noises from friction with the bottom door. A good solution to the latter problem is to place a carefully selected book(s) underneath for stability. There was an instance which I shall never forget when at The Royal Festival Hall a Fazioli developed a squeaking pedal, in the interval were a miriad of stagehands squirting WD40 (an aerosol oil) to solve the problem. I do not recommend you do this even if the required felt or leather is not at hand, try using a household candle. Hope this is of help

A squeak in a FAZIOLI!!! Now THAT is really something!

So much for the "appearance" of perfection, for the instrument I've referred to so often as the "Stradivarius" of pianos.

Thanks PNO2NER, Shadorunnr and Christopher Stubbs for your comments! With your imput, I'm hoping to resolve, temporarily or permanently, the squeakin' pedal syndrome......................Larry

I had a problem with a squeaky pedal. It turned out to be that the pin that acts as the mounting point for the pedal (I don't know the technical name for it) was broken and left the sustain pedal moving at an angle other than vertical. Interestingly, one tech. couldn't find it to save his life and another tech. put his finger on it right away.

I think you are hearing the plastic dowel that connects the key to the whippen. Have your tech use a teflon lubricant. DO NOT USE OIL OR GRAPHITE! PLEASE!!! It will make things look dirty and can even make things worse.

Indeed. I wonder what is going on here unless it is an attempt to show that the good old days when the "real" techs were on here (but who have since left in droves) were not much different or any better than they are now.

The best case scenario may be that a humourist has emerged into our midst.

Larry,

More often than not, we find that pedal squeaks on uprights come from within the action itself. The most common culprit are the pivot points (hangers) where the damper lift blade pivots to lift the damper arms.

If you open the upper case front and remove it, you can then reach around the left side of the action of the point where the damper pedal dowel intersects with the damper lift blade. Manually engage the dampers by lifting up on the arm. If the squeak persists (which is typically the case), then the squeak is within the action and really needs to be serviced by a tech.

We use Protek as the cleaner/lubricant of choice to "de-squeak" the hangers. This requires pulling the action and inverting it sideways to allow the Protek to penetrate the wool hanger bushings. Also, a couple of drops going down then damper blade itself helps "lube" the contact points with the felt on the damper lift arms.
