Thank you.
I have watched the tutorials on buying a used piano and the one regarding the nomenclature of parts (...I reserve the right to calmly watch all the others). What can I say, truly very instructive!
The piano is a truly complex instrument and, when preparing to purchase a used one, such complexity would require the evaluation of an expert and competent person (possibly a third party). As in all things in life, improvisation leads to gross errors. However, informing oneself requires time, study, and application. The alternative would be to trust the seller's advice, which could prove to be an ill-advised choice.
A real puzzle!
The opinion of an industry expert (as I was saying, possibly a third party) would be the most reasonable solution. But in small communities like the one where I live, the seller and the expert are the same person. There is no escape.
I think a "high-quality" piano should only be purchased if one possesses the technical/artistic maturity to choose it consciously.
In this case, however, I found myself faced with a request for purchase advice (...me, who has only been studying piano for a couple of years and owns a digital one?!).
To make a long story short, my nephew, an adolescent, attends a music academy (not yet a conservatory) and my sister has decided to invest in a grand piano. I visited various points of sale in my city and "tried" a few instruments. Mostly C3s... they throw them at you.
In light of what I learned in the tutorials, some were in really bad shape, even though they were refurbished. But is that actually true?
And, I repeat, with all the attention one can pay, if you are not a technician, perhaps many things cannot be understood. It is true, you can check the sound, the action, the hammers, the possible presence of rust on the strings, and any obvious cracks on the soundboard and bridges.
But how do you understand if the soundboard is "really" okay, if the piano hasn't absorbed too much humidity, if the somière (I believe that's how it's spelled) and the pedals are in order? You can't just go into a shop with a key and try them one by one...
And then the action... as a layman, I believe a rigorous analysis would require the "disassembly" of the wooden casing and the verification of the key action, one by one.
Among the many Yamahas, these days I tried a baby grand (187 cm I think) Krauss from '94. Really beautiful, round sound! But the price is too demanding (€15K) for an "unconscious" purchase.
Ultimately, my advice was to wait for the necessary time to be able to purchase a new grand piano. A good Japanese one slightly more expensive would be feasible.
I think that with a new one (that isn't entry-level), there shouldn't be any bad surprises. Aside from the rapid depreciation of the instrument.
I reserve the right to try the Kawai GX-2 (maybe a 3) and the Yamaha CX series (C2X and C3X if the price decreases). In truth, I prefer the Kawai action and sound (from the little I have been able to try), but all Kawai grands use actions with carbon components, I believe. Which, if I understood correctly, is currently an unknown factor.
If you could recommend some alternatives to the indicated instruments and within this investment range (€20K), or perhaps if some "series" turned out better... I would be grateful. I would have a wider range of instruments to work with, in perspective.
It is certain that I will continue to inform myself....
