Just what the heck is chipping? Rough tuning while plucking? Is there
something inherently different about bringing a freshly strung piano up to
pitch and in rough tune than doing a several-step pitch-raise? What is the
difference between chipping a piano up to pitch and raising the pitch of an
old upright that is 5 whole steps below standard pitch????
