Hi Joe, With respect, your experience in pitch correction is not the same as mine at all. A piano that is moved 12 cents will not be stable. The most recent example of this was a large old german upgright I tuned in England. I did a 27 cent pitch correction at A4. The tenor was somewhat flater and the last octave in the treble was 40 cents sharp. The piano was within 1 cent after the pitch correction, unisons were lovely and the octaves were very nice. The piano is equipped with humidity control. 24 hours later the pitch at A4 was 2 cents sharp and the tenor about 7 cents sharp. The mid treble was fairly stable but the top octave was again sharp--by about 30 cents. The bass on this instrument was slightly flat. There were also many unisons that had drifted. ===== Regards, Don Rose, B.Mus., A.M.U.S., A.MUS., R.P.T. 3004 Grant Rd, Regina, SK, S4S 5G7 Tuner for the Saskatchewan Centre of the Arts http://us.geocities.com/drpt1948/ __________________________________ Do you Yahoo!?
