While I do believe -- and have repeatedly both written and taught -- that there are better ways of designing pianos using what has been learned about soundboard function over the past several decades, I don't believe I have said the technology "destroys" piano tone. No, the two things I take issue with you over are, first, your claim that switching from the tuned backscale to the vertical hitch arrangement somehow caused the demise of the Baldwin company. This claim has no basis in fact and, at best, is misleading. The reasons for the Baldwin company's demise can be easily discerned by anyone willing to spend a few minutes studying the management the company endured during the last 20 or so years of its existence. And, second, I have said that I don't believe any form of backscale tuning will give the sustain increases you have claimed. A few months back you were claiming these increases to be between 300% to 500% (conservatively). I now see that you have apparently become a bit more conservative yourself and are only claiming increases of 100% to 300%. Even these figures I find astonishing. We currently have a Steinway A3 in the shop without a tuned backscale that has a usable sustain time at C-64 of between 12 and 15 seconds (depending on how you measure sustain time). Even your more conservative claims would have this increasing to somewhere between 24 seconds and 45 seconds just by tuning the backscale! Please forgive me, Dan, if I find this to be just a bit incredible. While you claim to have achieved these results in your demonstrations this has not been supported by the one person on this list who has attended your demonstration and written about it. (Were you going to respond to that by the way?) As may be, results of this magnitude would have rocked the industry. Not just from the inception of the technology but the rocking would still be going on. With treble sustain like this we would never hear complaints about weak and percussive (i.e., short sustain) killer octaves and we'd all be out there feverishly tuning away on the bloody things. Unfortunately we have never seen results of this kind -- not then, not now -- and the world is littered with pianos having weak and percussive killer octaves that no amount of duplex tuning is going to solve. Now, does tuning the backscale alter the tone of the instrument? Of course it does. As to whether or not this is desirable is another issue. Obviously, for you it is, but for me it is not. Nor do I care for the problems introduced by the technology and I really don't like the sound of the slightly out-of-tune 'tuned' backscale. Which is how most of them end up shortly after being tuned. And which is why so many of them end up muted out. As to whether or not this technology "destroys" the tone of a piano is surely subjective and, I think, overly strong. Finally, I'm not really sure what it is you want to have a match over. If you're going to prove that tuning the backscale alters the tone of the piano -- you win. It does. If you are promising to deliver on your earlier claim of sustain time increases of 300% to 500% (conservatively) -- now this would surely be interesting. I'd love to see a piano -- any (non-electric) piano -- with a C-64 sustain time of over half a minute. But I hardly need to engage in your pissing contest to see if you can deliver on this. I'll just attend your class the next time we appear at the same venue -- indeed, as I've said before, I'm looking forward to it. Del
