Hello everyone,

I was writing to ask for some advice, even though I already know it won't be very simple, regarding some difficulties

that I encounter on "my studio piano" for classical music, which is a Yamaha U1 with silent system.

When playing it, I encounter a "marble-like hardness" with subsequent pain in my forearms, both in the flexors and the extensors of the forearm.

I have tried other pianos, both Yamaha and others with decidedly heavy actions (from Petrof to Schimmel), and none of this occurred: to clarify,

I don't mean that I played on them for a quarter of an hour, but I have tried study sessions of even two hours with:

- scales and arpeggios

- Czerny and Loeschhorn

- studying classics from Bach's preludes/inventions, Clementi Sonatinas, or Beethoven.

Regarding this difficulty I encounter on my piano, which I have pointed out both to my teacher and to some tuners (2 in reality) who came to inspect the piano:

the latter informed me that there are no problems and that my piano is brand new from A to Z, in the sense that, according to them, it is a refurbished instrument in the true sense of the term,

i.e., done with all the proper standards, and if only all were refurbished like that.

The fact remains that I encounter these obvious and constant difficulties, for which I have had to organize my practice by taking frequent breaks, even during an hour or an hour and a half of study, every

10-15 minutes of actual playing.

That being said, since I would like to continue studying the piano assiduously and for more hours (which I don't do because of the pain), I was kindly asking if you could give me some indications

regarding the piano for the regulation of the action, or rather if there are things I can report to you so that you can get an idea and I can understand better.

My idea is to change the piano and not get one with a Silent system, which I have never used anyway, since the same tuners who came to see

the piano told me that modifying it is expensive and that they don't know exactly what result they would actually be able to achieve.

I am sincerely very confused and a bit frustrated by this, so I thank you in advance for any advice

or consideration regarding the matter.

Have the friction checked. The pins of the hammer cap rails, the pins of the jack cap rails, and the pins of the escapement upright cap rails must be checked. This should be done by a competent technician

Hi Paolo,

thanks for the reply.

Are you telling me to have this list of things checked because they are fundamental for the mechanics?

Thanks

Michele
