---------------------- multipart/alternative attachment Didn't someone at some time in the past do an experiment with a piece of wire with a heavy weight attached to it. He hung the wire for the ceiling, and measured the length of it over a period of time. I can't remember too many details, but I thought I read something about it once, maybe in a Journal. Will any of you with a CD do a search along those lines? Wim Maybe I'll spend some time tonight going through all my old Journals. It's time to dust those shelves anyway. :) In a message dated 4/5/02 10:25:25 PM !!!First Boot!!!, jonpage@attbi.com writes: > On the Mechanical Music Digest there are few people who insist that piano > wire does not stretch > and this is not the reason for multiple tunings required for a newly strung > piano.
