Hi Ed My understanding is that the parts that Grieg himself recorded are 100 % wax, but I can confirm this tommorrow. I do know that these old recordings have undergone at least two digital treatments. The ones used hear cleaned up the sound quite a bit but there is another job done (in England I believe) where reportedly fantastic results were achieved. I can find out more if this is of interest. You raise a point about an optimal response to some particular string tension. Very interesting point really. Clearly this instrument needs a lower pitch. That is to say if one does not find the killer octave syndrom an attractive characteristic... and I do know pianists who actually do like that kind of sound. I guess the point is that one can in some cases quite radically alter the response picture of the instrument by changing the overall string tension. Cheers RicB Nice recording, Ric. Is any of it 100% wax cylinder? The sound is pretty good on those sections. Nothing radical about the use of 435hz as a pitch standard for 1900. Given recent discussions about downbearing and soundboard stiffness, it isn't a wild leap to suppose that an instrument will have an optimal response to some particular string tension. (My 1892 Mathushek has it's original strings in good condition. I'll explore this when the action is restored and playing.) Ed Sutton
