Hi Newton, I was a little dyslexic when I posted that phrase, you are quite correct the addition of the unison drops flat. Trying to formulate consistent results is very difficult. Some variables that has got me wondering, Bridge stiffness left to right due to notching, treble string I think has a stiffer termination??? Centre line of hammer is firmer that the edges, this was in evidence with a new set of hammers, and how much voicing that was required to get all three strings sounding the same. On average voicing a bright piano drops the stretch 10c so what partial are we really listening to???? Is our ear fooled sub consciously???? e.g. at A6 no second partial is sounding do we revert back to the fundamental???? Like you I have very little understanding of what is happening. Slowly going nuts trying to find answers. Regards Roger P.S. Thank's for the correction. At 04:28 PM 25/11/98 -0500, you wrote: >"Interesting that your piano showed a *rise* in pitch.
