I need your opinion, but I hope to be able to explain my problem well; I have also seen the videos about the piano, excellent videos by Maestro Ferrarelli, but I still cannot understand. So, mine is a new upright piano, which I have owned for just over a year, and I have had it tuned three times so far, including the tuning on the first day it was delivered to me. The last tuning was carried out last November, so three months ago. Even before having it tuned in November, I heard some "buzzing" inside the piano, but after the tuning they disappeared (previously, from time to time, even when I wasn't playing it, I also heard knocks, like a "toc", like a string loosening, at least that is my impression), but as the days went by, the "buzzing" returned, at first only when playing certain keys, now when playing almost all of them: a light but annoying buzz. In past years, I dabbled in strumming the guitar, and I remember that when the strings were loose, playing them produced a buzz similar to what I hear in the piano; now my impression is this: is it possible that my piano was tuned at a lower pitch than normal, causing the strings to make noise, just like guitar strings when they are not tensioned correctly? And if, assuming my piano was tuned a tone lower, why did they tune it like that? When the technician came to my house, he smiled at me, declaring the work completed; I hope he wasn't thinking: "This Dominican immigrant in Italy knows nothing about pianos, so if I can shorten my work, who knows if she'll notice" ๐ต. I would like to let you listen to a recording of my piano's sound, but I cannot because neither I nor my husband know how to do it, and furthermore, we do not have a recorder. In the coming weeks, I must call the tuner back to kindly ask him to eliminate at least those buzzes. How should I behave with the technician to make him understand that I am not ignorant? I hope I have managed to explain my problem.
P.S. Furthermore, my piano has a rather metallic sound in the high octaves of the keyboard, while in the low ones it has a dull sound that makes me think more of the sound of a guitar than that of a piano. On YouTube, I found the following video of a piano similar to mine, with a beautiful sound, which my piano lacks instead.
