Problem with newly purchased piano
« on: January 28, 2016, 10:58:42 PM »
Hello,

so after a long time of trying many restored pianos I purchased 190cm PETROF from 1964, it have new strings and tuning pins, finish and it is regulated and renewed.  When i was playing it at the store it sounded really nice, strong clean bass and singing nice tone.


After it was moved to me around month ago it gone fastly out of tune, as it is winter now here and im heating quite a lot. It was tuned yesterday and after I had a chance to play it a lot today, I found that many higher notes have very bad shrill noise sound to it - not present there before the tuning and also the bass octave have now dull and tube like sound on many notes, it is really a bummer as before it was sounded much better and not had any of these artifacts, G and A notes in 2nd octave hase now some nasty buzz sound to them too, Im really frustrated as I bought new piano because of the nice clear bass and overal balanced  tone, now after one month and one tuning it started to sound like this. And Im not sure what to do now. The technician I bought it from is not from this city so it is not an easy solution (there is not any technician in the city...)  and I am afraid this will just go worse and worse - considering this purchase was bad maybe :-/

The fist thing I think of is this piano has to adjust to your environment but being winter and heating a lot as you put it that environment is ever changing. The best friend to you and your piano right now is humidity, you have to keep some level of humidity in the dwelling place. Ideal is 50% but even if you could muster 40% it will help . keeping close to your year round average on humidity will help keep your piano in tune and also sounding correct. Remember humidity is in that piano not just around it, it's in the felts, the wood, the sound board.

As to the latest tuning, it sounds like it was a lousy one LOL ! The good news is that it is just one tuning of dozens the piano will have in it's time of your ownership. Also don't be surprised with it having new strings and it going out of tune. Besides humidity levels in the house as a possible factor, those new strings will take probably 4 tunings before they begin to level out and you gain a stable piano.
Depressing the pedal on an out of tune acoustic piano and playing does not result in tonal color control or add interest, it's called obnoxious.

Hi.

Some things to remember is that your house is not the dealership, so the sound will be different for sure. Part of the tuning is to get it right to your ear and you may need to move furniture and carpets about. That will change the sound in the room.
So keep notes of what bugs you and let the tuner know.

Also I am intolerant, so if I get a tuning that is bad, I get a different tuner that is at least passionate and caring about his job. I expect a tuner to really know his job.

If the piano was redone, the action may still settle a bit and of course the strings adjust.
So likely you'll have to have it regulated and tuned to start after letting the piano acclimatise for about 3 weeks(Or you have done this already). Then wait about 2 months for a follow-up regulation (in a refurbished/new piano) and a retune.
I would then perhaps do another follow 3-6 months after that.

From your description a fair part sounds like like a tuning adjust. I wouldn't worry overly much yet. Just do as was said and retune every 3 months for the first year perhaps. After that, depending on the amount of play, every 6 months (I usually do that). One in summer and one in winter.

Thanks for the input


Im really stressed as it is now really soudns bad, shrilling sounds in full high octave. and I and II obass octaves sounds really dull, metallic / tubby with not any clarity. Any chord played there is sounds horrible. Need to solve this as it makes me not like to play it in this state.

It could be that the tuner/tech didn't do a good job - it's one thing to tune piano strings at the right pitch and another to ensure they will remain stable for several months.

Also, you mention the piano has new strings. If they are very recent, they will take a while before being stable, usually months. And/or it could also be just the seasonal switch in RH (relative humidity). As someone else said, it's important in winter to keep a decent RH level - it could be a room humidifier and/or installing a Dampp-Chaser system.

It's very difficult to evaluate what is the problem without hearing it, but it could simply be that the piano is out of tune again. A good tech can also attenuate the weird sounding partials in the wound/bass strings if you have this problem. Common problems for a brand new piano.

You might also check out your warranty - I would suppose you have the right to have problems fixed after your recent purchase.

there are any number of different reasons why your piano now sounds off or not so good as it did. The least likely of all those reasons ( the least likely) is that your piano suddenly and mysteriously turned into a piece of junk. it's the same piano is was before, it just needs proper adjustment. New pianos and rebuilt pianos take several tunings before they stabilize. It's just a fact. Don't discount changing climate in your house, don't dismiss anything that has been said above.
