xxx: I wanted to set up a piano at home, walked around and opened 1 site. The title of the article "If you are not an adjuster, then it is impossible to configure the piano yourself." Cool. Thanks for help.
YYY: It was very lucky. Usually the article is called "How to configure a piano yourself", and you 15 minutes read about how each of us sometimes need to configure a piano, how it was invented, what factories produce them, how to properly hold hands while playing... You get tired of reading, scratching to the end and seeing the last sentence - "if you are not an adjuster, then it is impossible to configure the piano yourself".
