Rolling is simply messaging the string to remove much of the slack out of the new string. Or you could do daily chip tunings and utilize much additional time. The bottom line is to get the piano stabilized as best as possible so that pitch can be somewhat maintained. IMHO, repeated chip tunings is cutting the dog's tail off and 1" at a time. How about string leveling and seating around the termination points? Are you counting on the chip tunings to eventually secure those points as well? Aside from rolling the strings, securing all termination points will allow the piano settle into a stabilized situation more quickly than doing repeated chip tunings. Tom Servinsky,RPT
