Piano is circa 1967, original owner.
The keys are not out of tune, but they sound bizarre. Twang is the best description I can come up with.
They all went at once; the first C below middle C, and the B & A next to it.
Piano is in reasonable shape, only moved once and always in a nicely controlled environment.

Expensive fix or...?

Thanks!

Probably not expensive but who knows.


The reality is that there is no definitive answer available on the internet--although dozens of opinions... Kinda like posting on a car site, "My car started running rough, is this expensive?"

Since the repair will have to be done by a human, it is best if you have a human with repair capabilities actually put eyeballs on the problem.
Do you have a regular tuner/technician?

Odds are that if you don't have a regular piano tuner, you haven't had it regularly tuned. And if that is the case, it could very well just be out of tune unisons (the two or three strings that make up one piano "note").

You have a piano and you don't get it tuned twice a year? Why, I'm SHOCKED, SHOCKED, I tell you! I never heard of such a thing.....

I'm not sure what "twang" means, but did you remove the kneeboard (the board at your knees) and look at those strings? Maybe something fell in and is touching them? Are you sure the Bb isn't twanging?

Yes, Bb is twanging as well. I did remove the kneeboard, didn't see anything that looked suspicious, but I'll check it again a little more closely. Thanks,

If you posted a video of what you are hearing, you would probably get an answer to your question. Just an idea.

Not sure how to post a video, other than youtube. I'll look into that, thanks.

If it has been a decade it wouldn't hurt to have the piano tuned. The twang will probably go away without extra cost.


I tune and repair pianos. Let's have fun!

Hi troop,

Your best bet is to get a technician to come look at the piano. It's been said before and it's worth saying again for the benefit of any others that read this thread. Read on for my theory concerning what's happening.

If the twang you hear is metallic in nature, and not the honky-tonk sound resulting from years of neglect and no tuning, you're probably looking at a more serious problem like loose windings or cracked bridges. Get a flashlight and remove the knee panel for a closer inspection. Follow the bass strings down to the lower right side of the piano, and you'll see two sets of pins: the hitch pins on the plate, which the bass strings are looped and tied to, and the bridge pins, which are set in a block of wood between the windings and the ties at the plate. Carefully examine this block of wood under a bright light, and if you see any signs of splitting, it's a fair bet that's your problem. Again, only a reputable technician will be able to confirm this. If you don't see any signs of splitting, mute the problem strings with your hand and play the corresponding keys. If the 'twang' diminishes or disappears, then you've likely got loose windings on your string. Have a reputable technician verify your findings, and be prepared to pay for replacement strings if the sound bothers you.

I share this information based on my previous experience with these pianos. The service provider I work for has around 30 in the client roster. Acrosonics have a longer life span than most other pianos that size, but 50+ years even with maintenance is a very long time for that piano and it's not uncommon especially in dry climates for things to dry out and fail.

Please keep us posted on what happens, and if I can be of any further assistance don't hesitate to contact me.

Piano owners posting here will appreciate, I hope, that technicians here love pianos, and that when an owner has not cared enough about a piano to have it regularly tuned and maintained, there is a limit to how much time we can freely give to hypothesising and elucidating possible faults.

Indeed, piano owners do appreciate the importance of maintenance; it makes me sad to hear of s neglected piano..., and I understand the free help becomes burdensome when it appears the owner is only during emergency surgery, Just like owning s car and not checking the oil until the engine burns out. I hope Troop will call a tech.

Thank you for your thoughtful reply. You guys are pros and do this on a regular basis. My parents bought this piano when I was 7 years old, and it never gave them any problems or concerns. I suspect most folks who don't buy high-end pianos live with minimal maintenance, as in " if it ain't broke don't fix it". While that may not put food on your table and may even be offensive to aficionados, the reality is that until a few months ago this piano probably hasn't seen a total of 20 hours of playing time in the last two decades. Not until Covid hit and I was stuck at home did I decide to try to re-learn the skills I had as a teenager, with 10 years of lessons.
