Good morning everyone, I am new to the forum and wanted to get some clarification if possible.

I recently inherited an old upright piano (yukino or something similar, the writing is hard to read now), I performed a general cleaning to free it from dust and to check for any mechanical breakages and/or various insects; everything seems to be in order.

The problem, if one can call it that, is that the tuning is a semitone higher on all keys; I checked the individual sounds with a professional chromatic tuner and the keys are exactly transposed.

The former owner is now unreachable, so I have no way of knowing if this was done by choice.

Do you have any ideas or suggestions?

…You surely declared it correctly…but are we sure? More than a semitone? Striking the 440 tuning fork, does that note correspond on the piano? A-flat or A-sharp?

Something doesn't add up. Would you mind recording the A of your piano and posting the file here on the forum? It's not a lack of trust, but to solve problems one always starts with the simplest things, and I wouldn't want your tuner to be calibrated a semitone too low.

thanks for the answers, certainly, as soon as I get home I will record and publish it.

l'unica cosa che mi è venuta in mente è che le corde sono tutte nuove, non vorrei che sia rimasto a metà il lavoro di cambio corde,

cioè mi spiego meglio, un mio collega mi ha detto che quando gli cambiarono le corde, gliele misero tutte leggermente in sovratensione per vedere se qualche caviglia non teneva ed era da sostituire, dopo alcuni giorni, poi l'accordatore venne a finire l'accordatura precisa allentando via via le regolazioni.

The mystery was discovered just as my friend hypothesized. I found the tuner's business card inside the piano, and he confirmed that the tuning must be finished after the change and they are all tightened slightly more. Thanks again for the opinions.
