For a couple of days now, my beloved little jewel (a 212cm grand piano with Langer action) has had a middle octave key that, in an absolutely random way, sometimes doesn't go down—meaning it gets stuck halfway through its stroke....but then once released, it starts working correctly again, and after a while the problem reappears and so on....let's say with an average frequency of a couple of times in an hour of practice.....
I believe it depends on the escapement lever, or at least the problem is related to the escapement, because if I try to play repeated notes very quickly without letting the escapement lever return, it jams very often and none of the other keys do this....
What could be causing this?? Is it possible that the roller has been damaged? Or the escapement lever? Even though at first glance, pulling the action out of the piano cabinet, there is nothing strange....at least it seems so to me....
Has anyone had similar experiences? The piano is almost new, not even three years old.....in fact, for everything else, it is perfect...the hammers are still perfect, I love the sound to death....but this problem is truly frustrating....I don't know what to do....heeeeelp!!!!
...you just have to have it checked by a tuner...nothing serious...if the piano is only three years old, it's almost new... you'll see that he will fix it in a few minutes.
It could depend on the escapement stud being higher than the repetition lever or its misalignment with respect to the roller. However, it needs to be seen; these are just hypotheses.
It could depend on the escapement let-off being higher than the repetition lever or from its misalignment relative to the roller. Anyway, it needs to be seen; these are just hypotheses.
Thank you so much for the suggestion!!! But are you a technician?? If so, what area are you in??
Also, I would like to ask you another question:
Lately, the humidity level in the room where I keep the piano has grown enormously....like we are well over 70% and anyway it never drops below 60%, do you think it's better if I purchase a dehumidifier? Could it improve the longevity of the piano? I would set it up in the opposite corner of the room....who knows?
Excess relative humidity can be harmful to the instrument. A dehumidifier is certainly recommended. Lowering the humidity can favor the functioning of the action, such as smoothness, and may even prevent changes in sound caused by the absorption of humidity by the hammer heads. Not to mention, the soundboard could suffer from swelling. Even tuning stability can be compromised.
