I've been kind of pondering the question this afternoon and found myself increasingly bothered by this whole issue. Specifically, the idea that the piano must 'project' out to fill an auditorium way bigger than it was ever intended to accommodate and filled with way more people than can comfortably hear and enjoy the performance regardless of what that 'projection' does to the musicality of the instrument. Perhaps it's time to put a Wal-Mart keyboard up there with a gazigawatt amplifier and umpteen dozen speakers and be done with it. Surely it wouldn't sound much worse than some of the poor pianos that have been stretched way beyond their limits. > > What constitutes 'projection' is an interesting question for which I don't > really have an answer, even though I'm the one who cavalierly tossed out > the term.

Well, you're assuming that this tuned-duplex system actually does improve that mystical 'projection.' I'm unconvinced. It seems to me--and I've not done any tests at all to confirm my ideas about this--that 'projection' depends on a rather percussive attack sound and, while that can be aided by a precisely tuned duplex, it is more a function of a very hard and/or dense hammer. But, as you say, why torture the pianist in order to get a little more 'projection.' It always comes at the expense of sustain and dynamic range, specifically at the bottom end. The piano loses the softness and warmth of pianissimo. It becomes simply loud and less loud. > > As to whether the > performer should have the worst seat in the house, that's another interesting > question.

Maybe. Then why not simply install a PianoDisk and be done with it. I don't go to concerts to hear a mechanical performance. I go to see and hear a real live human, one with emotions and a passion for the music. And, hopefully, some of that passion will come across during the performance. I don't see how a performer can get too excited about a performance when the piano sounds like a tin can and we tell him/her that this is to be expected because the piano must 'project.' But then, I find I don't go to very many concerts these days that are held in large auditoriums. Increasingly, I find them dead and boring and frustrating. On the other hand, we furnish a piano for a small recital room that holds about 50 to 65 people where I've enjoyed some of the most exciting performances in my experience. While the performers may not be World Class Pianists by most traditional definitions they are real people who are in love with their music and passionate about their performances. > > I think we already expect them to make some accommodations, such as > limiting dynamic range on the low end so that the sound will 'project' into > a large hall and to use a piano that is perhaps overpowered in, or biased > towards, the bass end and perhaps has a less responsive action than a > smaller piano.

And it's the main reason why I no longer worry about achieving a high level of 'power' in a given piano. Power will take care of itself. I'm much more concerned with the dynamic range and the bottom end performance. > > I think we have created an untenable situation with a concert hall that > holds thousands of people.

I think you're right. I wonder just what the optimum size for an auditorium is considering the realistic performance potential of the modern piano. By that I mean one that is not stretched beyond its musical limits simply for the sake of 'projection.' I would guess one seating around 500 to 750. But, again, I've done no definitive tests on this. Just some observations. Del
