Could you please expand on exactly what do you mean when you speak of = the poor string termination of the capo d'astro bar configuration. What = is poor about it?=20 Just that it is usually rather inefficient. The length of the duplex = segment (relative to the speaking length) and the rather shallow string = deflection angles always allow some energy bleed across the V-bar.=20 How does it compare to the agraffe? I understand (I think I might = anyway) about energy losses associated with aliquot systems, but what is = inherently or potentially bad/inefficient about the capo design compared = to the agraffe design. Thanks for any thoughts you may have on this. The agraffe also has some energy losses due to their flexibility and = their relatively low mass compared to the capo d'astro bar. So, to some = extent I think you pays your money and takes your chances. I now believe = both systems can be made in such a way that they might be quite = inefficient or quite efficient. I'm not sure which is inherently = superior though I expect the scale is tipped toward a well designed capo = d'astro bar system, though not necessarily with a V-bar. And certainly = not with the string deflection angles and duplex lengths we've come to = expect in the modern piano.=20 I'm also not sure the benifits of this ideal system would be so much = greater than than a really well designed agraffe system as to be all = that noticable. We do tend to get hung up on the esoteric that the = obvious slips right on by. Oh, and thanks to Brain Trout, I found your soundboard papers on the = Journal CD - these are the ones you refer to that start in December = 1997? That sounds about right. I really didn't keep track of the publication = dates and all my Journals are temporarily unreachable. Del ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
