pitch rise /was: no tunings, no drivel

[D.Martens]

Hi Don,

>>I have measured as much as a 40 cent pitch >>change at
>>A4  (A450) (10 hertz), but I have never seen a >>string break from this
change.

ok, how do you explain strings that do break under these conditions  ( I
mean, the highest wound strings, when the piano rises due to weather
conitions ) ?
