Hi all,
Given that I'm not a professional tuner but have been tuning my upright piano for 30 years, I now have a baby grand Kawai GL-10 piano that needs more frequent tuning than upright. Is it just because it's new? I don't remember these problems with the upright.
I can't just rely on a professional tuner because when a note or two start detuning and meowing, what do you do, you call him? no, of course you will call it when the piano is well detuned but in the meantime the few detuned notes are a punch in the stomach.
Also, the last three single-stringed notes, before the two-stringed ones begin, have a very nasal sound. Some advice?

Thanks to all

A new piano will generally go out of tune faster than a piano in good shape that isn’t new. Also, a piano that was recently moved may take some time to settle into the new environment. Also, if the grand is in a different spot of the house which is more subjected to temperature or humidity swings then that could affect it as well.

That’s on top that pianos have their own personalities when it comes to tuning.

You didn’t say how long you’ve had the grand piano.

New strings take time to stretch out.

Some notes have 2 or 3 strings. Different lengths per note and go out of phase.
An ongoing dillema. The more you tune it and keep temp/humidity constant the better it should stay in tune.
New strung pianos expect around 12 tunings before the speaking length of string settles down.

That 'nasal' sound may just be part of the design for this short piano... There are limitations that the crossover between bass and tenor reveal on many instruments.

A 30 year old piano vs a brand new one...yes, there is a difference. It generally takes about three years for it to settle down realistically. Also, you need good humidity control. Finally, you are talking the bass/tenor break which is always problematic on overstrung pianos. You need the services of a skilled tech who knows voicing and mass loading of the soundboard. If you look onside you will see that the last few notes in the tenor are in a completely different area of the soundboard, are on a separate bridge on the soundboard, AND have different wire than on the bass strings. Adding to that is the physical weight/size difference of the hammers right at that point. Yes, there is a reason why those notes sound "different"...a good reason.

i understand, but so, why only 3 notes sound different? Not only that 3 strings are hosted in a different armonic table.
Descending from hight to low notes, its are the first 3 notes with one string. all other are ok, of course i do not have the bass of a 278 piano, but at least not nasal.

A precisation, i bought my piano as new brand, but now it is 2 years old.

Even i think to be good in tuning, once per year i call the tech, and i will talk about it, thanks
