Mike at Cincinnati: Thanks for your clarification on
acceleration vs. speed. It's an important point to be
aware of in this discussion. I don't think, however, that
analyzing the acceleration of a key/hammer system with
touch weights will reveal anything pertinent to inertia
as it relates to the pianist.
Okay, Ken, I can't let you get away with this. Give me more
support for this statement.
By the way, too little inertia is also a problem for actions.
The pianist will claim that he has no control especially when
playing soft. If your school is like ours then you must have a
few of those Steinway Teflon actions which you have completely
replaced with cloth action parts from Renner or Steinway. These
pianos are very difficult to correct. We even had a series of
Steinways with Felt knuckles and teflon action parts. These
pianos require something more than reweighing and trimming
hammers. This is my motivation for asking about all these
things.
