Terry, >I was not aware that overpulling a string during a pitch raise could affect >the sound production characteristics of a string.... any more on this? Normally as you add tension that's all you do, and if the tension is released the wire regains it's former shape and size. However, as the tension of the string approaches it's breaking point it undergoes what is called plastic deformation. (I _think_ between 70-80% of break strength.) That is when the wire no longer will regain it's former shape when tension is relaxed. This might be imagined as a taffying out of the wire, or where one weaker section stretches faster and thus becomes thinner. Strings in portions of some scales are around 60% of breaking strength when at pitch, so you can see that with so little "wiggle room", pulling _way_ up over pitch could easily get into the plastic deformation range and induce (at least) false beats. Someone else like Ron or Del could probably rattle the formulae right off the top of their heads. Conrad Hoffsommer mailto:hoffsoco@luther.edu Chi si ferma è perduto.
