Salut Michel, The pitch raise itself takes me about 20 minutes. Then there is the usual tuning. Usually, after the first pass, I'm within 5 cents of A-440. If the piano hasn't been tuned for over 5 or 10 years wich is kind of frequent, I won't mind it being within 5 or 8 cents flat or sharp anyway. I recommend tuning the instrument within the next 2 months. Regards, Marcel Carey, RPT At 15:22 97-09-27 +0000, you wrote: >Hi Marcel, > >Two questions: > >1.
