How “good" of a piano should I buy is a question probably asked since Bartolomeo Cristofori made his second piano. It is actually a pretty easy question to answer with the standard "buy the best one you can afford" retort, but that seems a smug answer to the uniformed. In most cases the "uninformed" is the non-playing spouse of a player, and the non-playing parents of a student. And what is a "good" piano anyhow? For most individuals it IS the best piano you can afford. Let me explain in simple terms, the first rule is that you can only play as well as the piano you must practice on performs. If a beginner is forced to play on an instrument that will not hold a tune, a couple of notes do not work or are sluggish, and does not respond well (bad action), their learning process will be severely stunted, and they will probably quit. A good piano for them would be a particularly good sounding instrument with a smooth well-regulated action that would encourage a student to play it. These pianos tend to cost a more than the "entry level " piano shaped objects out there. For intermediate to pro level players a good piano for them is one that meets and even may surpass their skill level. These pianos go up in price as the tone and touch quality rises, but you will play better on a better piano without a doubt. So, the bottom line? Get the best piano you can afford; it will be money well spent.
It may sound crazy at first, and your initial response might be "I could never do that" but the best way to enjoy playing the piano and making music is to share it with others. Yes, I know most people do enjoy playing for just themselves and their own amusement. And that is great! But they would probably find it even more satisfying to play for others. Now I am not saying you should book Carnegie Hall (maybe just not now, but you never know) but as simple as immediate family members for starters. Get comfortable, graduate to extended family, then on to friends and strangers at parties and other get togethers.
Now that we have addressed let off, drop, and repetition lever spring adjustment in our previous discussions, rounding out the four primary adjustments is the back-check.
The back check itself is a small wooden block covered with a small piece of felt, over which, a strip of leather is stretched. It is mounted to the back end of the key with a wire that provides easy adjustment.
