This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Hello List This post is inordinately long, so I have started afresh. I _think_ it = was David Skolnik who said: " For example, if the string were to = traverse the bridge, captured by the pins (horizontally) , but at 1/16th = or 1/32' above the bridge surface?" It is, as I see it, the opposing = angles of the bridge pins which keeps the string in firm contact with = the bridge top. There can be Negative Downdbearing - yet, because of = this " opposed angling pins" format, the string will be in firm contact = with the strings (unless you loosen off the string tension). Imagine a = fiddle - or 'cello - the string has very firm contact with the bridge = and there is immense downbearing - except that the strings used are not = of the piano variety. It goes without saying, of course, that the = downbearing will diminish as strings are loosened off - but which = measurement should be taken note of? the measurement _before_ loosening, = or the measurement _after_ loosening off the strings. I feel that the = closer to Zero downbearing in the fully tensioned strung piano, the = fuller the tone and the longer the remanence after the string is struck. = The remanence decreases in inverse ratio to the downbearing. The more = downbearing:the less remanence. There is also another thread being = introduced on the list lately: That of the effects of wave-form = cancellations in the grand piano (the uprights are usually against a = wall and therefore don't count so much) This cancellation effect is = taken from the difference of the wave-form taken from the string side to = that taken from the rib side. It seems to me that if it were possible to = invert the rib-side wave-form we should end up with a very improved = sound as it would add to rather than detract from the rib-side = wave-form. It is the rib-side wave-form which is hurled into the = audience by the open top lid..... but what happens when that lid is = removed I ask? Surely the cancellation effect is greater! Over to you.
