Hi Warren, I had missed the meaning of prang in your message. In a situation, where I think there is a danger of string breakage, I like you would do a 2 pass for over 100c. But I would not have the overshoot. 125c I might just do the 1 pitch raise, then fine tune, if I think it can take it without string breakage I know it will still be off by a few cents, so I suggest that I come back in 3 or 4 months, and then the piano will have settled out and accept a fine tuning better. I also say, if the tuning bothers them to call me within a week, and I give them a special price. In all the years I have been tuning, I have only had one person call me within the week. Sorry, I missed the string breakage inference, on your first posting. Regards, John M. Ross Windsor, Nova Scotia, Canada piano.tech@ns.sympatico.ca
