Once again, based on the circumstances, tapping tuning pins is a great asset, both on inexpensive and expensive pianos when the tuning stability starts to become marginal due to tuning pins that will no longer stay in place. As to 'driving' the tuning pin versus the expression I am using, 'tapping' the tuning pin, I only tap the pin enough to witness a slight movement. Anymore than that is unnecessary in the majority of the situations I have experienced. And as to the concept of only establishing new grip at the bottom end of the tuning pin, I respectfully submit that the entire surface of the tuning pin hole is affected by this tap, thereby creating more than ample friction to introduce holding power once again. There just too many pianos I have done where the tuning pins are holding quite well, pianos that I tune twice a year minimum, and have been doing so for many years.
