The only direct comparisons or experiments I've heard of have involved taping--actually felting--off the tuned duplex string segment and then concluding that the thing works because when it's felted the piano has less sustain and 'projection.' Well, of course it does. That's what happens when you put a damper on the string--even if its a damper that's only applied to a part of the string that shouldn't be speaking on its own but is designed to absorb energy from what should be the speaking portion of the string. So, to me, at least, the question is unanswered. What constitutes 'projection' anyway? Should we be building pianos for 'projection' at the expense of musicality? Should the seat in front of the keys be the worst seat in the house? If so, how can we expect the artist to create wonderful, dynamic music when it all sounds like garbage at the piano? Or should we be working on remote keyboards so the poor thing can be played from the tenth row back? Del
