Following are responses to various posts about inertia: Vinny at BYU: I will comment on your "D" when I have more time; many things cometo mind 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. Pianos I have encountered with lots of inertia seem to be fine for pianists until they try to play them fast and loud. At that point, all the inertia in the piano becomes a problem as you try to accelerate/decelerate it real quickly many times per second. Do I make sense here? Bill in sunny CA: A hearty amen to the heavy hammer caution. You're abso- lutely right about the all too frequent attempts to put much heavier ham- mers on pianos that had light hammers to begin with. All the additional leads neccessary to try and bring the beast into touchweight specs just exacerbate the inertia problem. And if I may, Bill, be frivolous for a second, I'd like to add a personal note to you (everybody else get off line now). I wish I could windsurf on lake Erie now but my daggerboard gets caught in the ice!! (Hope you don't mind my little joke) Inertially yours, Ken Sloane, (COLD) Oberlin
