Tunelab question

[Jason Kanter]

I think that the pitch is in fact higher at first and then settles, as the
force of the blow is dispersed. You ought to be able to see this phenomenon
more with a stronger blow.

Hello everyone!

I've tried using Tunelab as a teaching tool and noticed,
that the phase display for a note that is close to pitch,
first moves to the right for a few seconds after striking
the key, gets slower, and then moves to the left.

Is this "pitch change" an actual phenomenon in pianos or an
artifact of sampling in the computer? If it is the former,
what should you use for tuning? The stabilized display, I
guess, since this is what you would use with aural
listening, right?

Greetings

Michael
