Thank you for the very quick and rich response.
Yes, it is clear to me that, to determine if my piano can become more suitable to my characteristics, it is essential that a technician be able to "visit" it, and for me so far the problem has been precisely not knowing a technician with whom I could have a dialogue like the one I had with you, even just with this "back and forth"; to put it another way: it seems to me that you possess a competence and, above all, a sensitivity that are not quite common.
As far as my characteristics are concerned, I am an amateur with limited technique, but who can dedicate—and loves to do so—several hours to improving; the point is that with my C7 I cannot study much, because I feel myself quickly reaching the threshold of tendonitis.
I am well aware that a consultation with a highly experienced technician could result in verdicts such as:
"the instrument is very well regulated, and would be the joy of many pianists, but it is not suitable to your limited means"
or: "it is you who are not suitable for it because you don't know how to practice!",
or: "the environment in which it is located, even if it is 42sqm, due to its structure (reinforced concrete), shape, number of windows, and lack of furniture, greatly affects the sound in a way that cannot be rebalanced with mechanical adjustments"...
But, to make the best use of the expertise that an experienced technician like you can offer, I believe it will now be useful for me to get to know a few more pianos: I always play only on my piano because, for many practical reasons, it has been difficult for me to try others so far.
I can tell you, however, that two years ago, while randomly trying a grand piano, I had drastically different sensations from those I get from mine: that piano was much "easier," but also more intuitive, and above all, I managed to bring out so many of those nuances that when I play on my instrument I am unable to make emerge; in fact, I had even forgotten that I was trying to achieve certain effects. In short, from that experience, I have the impression that many of my phrasing intentions remain somewhat submerged or "implicit" when I play on mine. However, I certainly cannot draw great conclusions from an occasional one-hour trial on another instrument.
But now, thanks to you, I have regained the desire to explore new solutions.
I will go and try other instruments to have points of comparison and then I will try to contact you.
Thank you again
