Ron and David (and whoever doesn't have any better idea of how to spend a Saturday night), The argument laid out by Ludwig Riemann in Pfeiffer is tantalizing in all that it has to offer, the arrival of more consistent dip between naturals and sharp and the reduced and easier height of the sharps, both of which the pianists will thank us for. All we have to do is set all the balance pins in one line, that's all it costs us. Probably bringing the sharps' balance points away from the capstan would be a better arrangement than moving the naturals in towards the sharps' balance line. It would seem to avoid squashing the leverage into too small a space. But even doing this relocation of the balance line (by moving the sharps), the consequences to the leverage of the key such as David has observed is difficult to ignore. David's metrology may seem to exist in a universe parallel to that of linear measurement of key lever ratios: in fact, it is simply measuring the leverage by weight. I like my keyboards at .51, and I have seen key lever ratios of .59. But I am not looking forward to meeting at keyboard with .79 ratio, especially the group of .79's was in fact the sharps, and I was supposed to set aftertouch and not worry about dip, and furthermore, to expect to rebalance a set of keys whose leading had to answer to a 5.5 total leverage on the naturals and (way up there) 7.5 on the sharps. Certainly I'd love to play on one of Chwatal's keyboards for the freedom allowed once the height of the sharps was reduced. And I might even be able to play beyond the effects of the action ratio on the front weights and key dip. But then pianists can learn to love anything, as long as it sounds good. Who remembers the grands up in the Pacific Northwest with no front leads and the hammers ground down to bring the balance weight within playable range. There were many pianists who loved these pianos. I believe I remember Don Mannino reporting favorably on one on this list, a few years back. But getting back to the "tomahtos" and "tomaytos" in Ron and David's remarks, Ron's challenge that David should refute each of Riemann's reported advantages is not required. I agree that what Riemann says in is fact there for the pianist to enjoy. The issue is a little larger, namely whether the side-effects of such a redesiging of the keyboard is a reasonable price to pay for it. You say key height and I say inertia....let's call the whole thing off. Mr. Bill Ballard RPT NH Chapter, P.T.G. "Can you check out this middle C?. It "whangs' - (or twangs?)
