---------------------- multipart/alternative attachment Over the winter break I have restrung the top two sections of 2 concert gra= nd's that were getting in the habit of breaking treble strings far to frequ= ently. I've done this many times on the practice room pianos. We've discu= ssed this before with regards to the uneven tension when two sections are d= one and tension is left on the rest of the piano. =20 Just out of curiosity when I got the treble strings off, I measured the pit= ch of C5. It was 76-cents sharp. After I installed the new strings and pu= t enough tension on each unison so it didn't sound funky and enough to keep= the coils tight I measured again and C5 was down to just 16-cents sharp. = I then chipped twice and measured again and C5 was down to just 4-cents sha= rp. By the time I started to actually "tune" it, C5 was just barely off. Since the sounding board could raise the pitch that much, is this a good in= dication that it has not suffered terminal compression set? It would seem = to me that the board would still have to have some life in it to do that. Ideas?? dave __________________________ David M.
