Lovely OverDamper Piano

I have some input into the subject of 'ringing dampers'.
Some of the North American pianos, of the earlier part of the 20th century, had dampers that were not as efficient also.
They had terms like resonant whatever. They liked the 'ring', in those days.
Just because a piano was manufactured, as the birdcage etc., with an after ring, does not mean that we have to stick with that. The customer should not have to put up with this after ring, if they don't like it, just because that is the way the piano was 'meant' to be.
If we can modify, or reduce this 'noise', then we should.
This German piano I tuned recently, was a birdcage, Ibach I think, had a minimal after ring, so the birdcage, can obviously be made to have a more efficient damper system.

  Wow, that's surprising.  I thought it was a deficiency of modern upright dampers that they don't damp (not dampen! :-) near the strike point, like grand dampers do.

    ...the closer you get to the string termination the less effective the damper will be to absorb the vibrating energy. This fact was established in the time of around 1850 or so. Sooooooo, again, The Over Ring IS intentional and should only be moderated, NOT eliminated, because it is impossible, given the action geometry & physical characteristics.
