---------------ORIGINAL POST------------- Now, to the discussion at hand. Thanks, Ken, for maintaining the importance of hammer weight in this complicated equation. Remember, folks, there is a VERY important dynamic property called INERTIA that has to be figured into the equation. The downweight and upweight can all be perfect but if you are using a hammer of improper weight, the tone of the piano will still be very limited in dynamic range and color potential. It might be an interesting demonstration to have several different action part combinations in a piano and see how the tone (and repetition) is really effected....any takers? Or has it already been done?

I am teaching a class about this instrument and its two actions at Albuquerque in July. Ken Sloane, Oberlin Conservatory
