I appreciate your comments. Thanks.

If you look closely at the second set of graphs and compare the left and right graphs of each of the three measured parameters from the instant of hammer/string (hs) contact, you will see that the post contact key and hammer velocities are nearly the same and that the waveform is essentially identical, in spite of the left graph set showing a pressed key and the right graph set showing a struck key.

Note that the final velocities of the key and hammer at string contact and the amplitude and partial structure of the resulting waveform are the same left to right as well. It clearly shows that the whatever happens with the action prior to the hammer strike, the result is the same.

So it possibly comes down to a question of whether these very minor differences can be detected by us humans!

If a hammer is striking the string before the damper is clear, the action is not properly regulated and any pianistic techniques to somehow mitigate this mechanical issue are not ones that would find a more general application.

There are some technicians who in an effort to "lighten" the touch they place the damper lift later in the key stroke. This creates many issues. One you may notice is when escapement and damper lift occur simultaneously instead of damper lift preceding the escapement point which is the norm, is that playing soft and even becomes impossible.

The most productive way to lighten and action is to reduce the weight of the hammers. A small amount of reduction has a profound effect on control. Even if the down weight is reduced by only 1-2 grams; becuase the hammer is the predominant factor in the inertia of the action, you will notice a big difference when you play.


In a seemingly infinite universe-infinite human creativity is-seemingly possible.
According to NASA, 93% of the earth like planets possible in the known universe have yet to be formed.
