At that early stage, the lower cost Conservatory was much more stable, even though it is identical in design except of the shared strings. After some time and enough tunings, the stability is the same. Jerry, The strings on the Erard in question were new in relation to the age of the piano, but had been installed a couple of years ago or more. I was quite surprised when a 100 cent pitch raise that was targeting A at 438 ended up 10-15 cents above A 440 in the middle of the piano. It seems logical to me that pulling on one side of a looped string would affect the other side of the string to some degree, however small. The individual string could only affect its neighbor via bridge/soundboard flexion. I have not researched this, so I haven't any data other than the aforementioned experience to back up this hypothesis. I did find it quite curious, though. In doing pitch adjustments with Tunelab for the last 2 1/2 years, I've never had this happen. I always end up very close to target pitch. I'm just glad I didn't target 440!
