Good morning, I am writing here to share the experience I am having with my piano in search of answers. Some time ago, I purchased a Yamaha U3H upright piano. I am realizing that I have some problems with the piano's keyboard. I cannot understand if it is too light or if the sound of the piano is too loud, but I always find myself having difficulty when I have to play parts softly and very softly. Furthermore, I find it very difficult to manage to keep a stable sound or to perform staccatos softly. The problem is that with my teacher's piano none of these problems occur, so I think it is a problem with my piano! I ask everyone for help!
From what you are telling me, your piano lacks precision regulation. Poor regulation prevents the pianist from playing especially the pianissimo and from having a good dynamic range between piano and forte. Along with this, the hammer voicing must always be kept under control. After each tuning, it should be corrected, minimally, without altering what was done by the Factory—specifically, the voicing. Be careful that the hammer rail is not nicked at the apex (in addition to a small cushion called the "pianissimo cushion"). Excessive voicing (which is often confused with improper and harmful "softening") can damage the hammer rail and be irreversible. Never shave the hammer rail; if necessary, do it lightly while strictly preserving, especially in the treble, a "diamond-shaped" hammer form and not an improperly rounded one !!!!! (let's hope this hasn't already been done before the sale!!!) This would also cause irreversible damage to the structure of the hammers. The technician must be an expert.
Thank you very much for the quick response! In the meantime, I want to compliment you on your advanced preparation. The only problem is that I am not an expert on the parts of the piano or how they work; I just limit myself to playing it. Do you think I should request a technician's intervention? And if I must, what can I ask him? Sorry if I don't know this field well, I've only been at it for 1 year and I am a fairly young guy
