[CAUT] scaling a Tyre harpsichord?

[Ed Sutton]

So if the strings are breaking when the humidity rises after being tuned to pitch at low humidity, you have your answer. Consider lowering pitch proactively. 

It may be possible to install a rod and humidistat through the belly rail.
There's usually a mouse hole behind the action.

  300 cents rise or swing from flat to sharp?  300 sounds scary! I've probably had 200 cents total variation flat to sharp, but nothing that drastic from a440
