The discussion on breakage is very enlightening. Can anybody address the subject of breakage re: defective string? Is it possible that a piano could have been manufactured with string that is defective in some way? I deal with a Kawai baby grand that resides in a practice room used exclusively by men. It gets heavily abused. It has broken most of the top two octaves in the last year or two. But not only that, there is an odd buzzing that starts around middle C and proceeds for about the next two octaves or more. I've already checked bridge seating, and cannot locate the source. Any other suggestions for places to look would be welcome. I think it happens with agraffes and with the capo. Not only that, but the mid and high treble strings have a really weird, rubbery, elastic feel. They do not respond at all to conventional hammer technique. When I think it's stable, then the test blow sends it diving. I have to leave it sharp and pound it until it stops drifting. I do need to shape hammers, and that will help. I'm debating whether to replace all the strings except the bass section this summer. Those I've already replaced seem to have none of the problems I've mentioned. Greg Soule Pensacola, FL
