One and a half months ago, I tuned a Steinway 1/2 grand piano setting the tuning to 441 Hz, as per the owner's instructions. After about 20 days, I replaced a string in the upper octave and rechecked the tuning; it "held" the 441 Hz well.
Yesterday I returned to tension the replaced string and...........I found 2/3 of the piano at 444 Hz!!!
How is this possible?
When does such a rise occur?
Is it necessary to bring the pitch back to 441 or will the piano settle itself?
Thank you, as always. Greetings, Raffaello Angelini (L'Aquila)
I believe you, but mine looks very strange. The environmental conditions should be checked very carefully. If it happened in the bass clef, it is possible, even if unusual. Perhaps it is better to wait and check again. Another possibility is that the pitch raise to 441 was not set correctly. Honestly, this has never happened to me

Normally it happens due to high humidity. When the humidity drops in winter, the piano will return to 440 hz.
