Hi all, I am still pursuing humdity effects on pianos. The piano: Young Chang G-157 (small grand) ten years old tuned four times in the last year. The conditions: Humidity on Feb 3 2000 was 22% Humidity Aug 1 2000 was 51% The observsation: In every 3 string unison the "bass wire" was significantly flat of the middle wire and the "treble wire" was significantly sharp of the middle wire. I did take time to measure c7 which gave the results b = +6 m = +12 and t = +19. There were many notes that had an even greater spread, but I feel this note was probably typical. Would anyone else like to confirm these oberservations? Please? Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.M.T., R.P.T.
