Thanks, but I can't actually take the credit for finding it. Another piano tech by the name of John Delacour shared it with me. He has been interested in proof of this happening for longer that I have, and in fact it is attempting to work out a way to measure this happening so as to put to...

Ok, I have found a scientific paper that comments on this: (i think) ---- Tensile Stress Relaxation in High-Strength Spring Steel Wire Sinha UP, Levinson DW Abstract Stress relaxation data were obtained in tension tests using the vibrating string technique (measuring the resonance...

Your comments are very helpful. Thanks for clearing up a tiny corner of my wordview. [inkling]

Ok, I need some help settling another piano tuner argument. When a piano string breaks and is replaced with a new one, it takes many tunings until it becomes stable. It can be brought to the correct pitch, and will seem to stay there, but in a few days it has dropped in pitch drastically...

I found this: (here: http://www.mmdigest.com/Archives/Digests/200204/2002.04.02.08.html) I don't need precision, I am trying to get ANY idea of the size of motion we are talking about. [kurt]

Agreed. I guess what I am looking for is some idea of how tiny the pin movements need to be to get a really perfect note.

On a piano tuning pin, there may be 4 coils, but they lie along side each other- the wire never overlaps itself. The termination point will always be flush against the side of the tuning pin. The extra coils may indeed cause the pin to act stiffer, but we are ignoring flex or twist at the...

Hello everyone, I am new here and so I apologize in advance for the many forum faux pas I am likely to commit. I am not particularly well educated in the field of physics, but I am a piano tuner by trade, and we work with issues every day that are basically problems of physics and engineering...
