Hi Mr. & Ms. Technicians,

I know that in a new piano during the first couple years a few things can happen and they are called settling in. These things can affect the tone of the piano. For example, the hammers can get compact and the piano start to sound bright.

I read that the strings will stretch during this time. I assume it means the strings lengthen under tension. As the string lengthen I suppose the string would become thinner. How would this lengthening of strings affect the tone? I mean the tone not the pitch.

What about the soundboard, bridge, rim, harp? What would happen to them and how would they affect the tone?

As the piano continue to age past its break in period, what should we expect and how would the sound change?

Thank you!!
