Ok... sounds agreeable enough. But in principle does the, I suppose hypothesis is the word, does this sound reasonable ? Cheers RicB To answer your question you will have to take measurements. That will require a method that can be repeated with enough precision to give useful information. The bridge movement will vary depending on the energy inputs from the strings, so the input must be controlled, as well as the time of measurement. Labs would most likely use an electromagnetic drive to move the strings. There are many variables at work, including our need to believe we know what we are doing. I have proved this many times.
