On march 6th you wrote mentioning hearing a loud noise, as if a string had broken - do you think that might have been the crack happening?
Yes it seems very likely that that could have been the start. I went to inspect it each time I heard the noise and there was nothing to see, but it could have been the wood starting to shrink and then it's suddenly turned into a crack, as rapidly as a sheet of glass or ice cracks once it's started.

Take comfort from the man at Besbrode who said a crack didn't always matter.
I'd forgotten that, thanks for reminding me - I'll keep my fingers crossed.

It might be worth addressing the humidity though, and getting one of those reservoir things to dangle over your radiators (Betterware catalogue) - hard to imagine a change in environment having such an immediate impact, though; perhaps it was the move that jarred it?
I've put a bowl of water near the piano in the meantime. I had in mind to get a humidistat once the piano was restored and working. Assuming that the piano isn't a write-off which doesn't bear thinking about

I'd better make this a priority. I didn't think a change of environment would affect it so quickly either, otherwise I'd have taken precautions earlier.

Hopefully your teacher can tune round it.
I've left a message with his girlfriend and she's going to contact him and ask him to ring me back...
