Hi Avery and list, Some of my opinions related to the subject. The strings,soundboard,the hammer and even the case all contribute to the sound,that means the tone (and also the pitch) is determined by the string, soundboard, string termination,etc. The string is going to stretch and become thinner and harder,this will cause pitch change. The string termination is also going to change and cause false beats some times.what's false beats? that's "pitch instability and floating--another way of pitch change. Last summer in Reno,I took a very good class about bridge rebuilding instructed by Ron N.Ron found that the bridge pin is going to move up and down in the bridge due to humidity change. Because the brass bridge pin has a a deep mark which is compressed by steel string,the moving pin will cause the termination change and has a influence on pitch. String has partials,soundboard has it's own modes.When piano create sound,soundboard and strings coupled together via bridges.so any factor influenced soundboard modes(like humidity) would has more or less influence on the pitch. when we listen a pitch, we are listening the pitch of the whole piano,not the string's frequency,not the string's partial.In my opinion,we have pay much more attention on the string than the soundboard and other "non-string" factors while we talking about the piano's pitch.
