I always tune the piano, and I call the tuner once a year.
I believe that for someone who plays the piano, even with a single out-of-tune note, it feels like a punch in the stomach. I believe every pianist should at least know how to fix a few isolated notes, because even for someone who studies seriously, when a cluster of notes goes out of tune, do you call the tuner?
Having said that, the high notes, those without dampers, are very delicate. I cannot tune them "straight," meaning without beats, otherwise when I play a scale it sounds fake. How should they be tuned? Should they be left with a minimum amount of "meow"?
No, they must be tuned in unison. However, in high-quality pianos, the left string is left slightly floating in the mid-high range to favor the cantabile, but this must be executed with mastery. Furthermore, it should be noted that especially in the highs, the position of the hammers' striking point is fundamental, which can alter the good quality of the sound.
what I was thinking, not having a high-quality grand piano, but a Kawai GL10 which I will soon replace with a Yamaha C1x, tuning to unison and playing a scale from C7 to F6 sounds fake.
