Sudatory, hmmm... I had to look that up. Same as sudorific = Causing or increasing sweat.
Yes you can say that again ! Bloody hard sweat work it is
I'll never forget these summer evenings practising the Orgelbuchlein bare-chested, sweat pouring down my back. Luckily my new venue is a bit cooler (and warmer in the winter).
Btw, I was more thinking of the sweat, which can increase, if you are afraid of something. In your case I was thinking of your organ examination. So, my "sudatory" (I got that word from Leo online dictionary) was meant not to be caused by a too large heat, but such "missunderstandings" - intentional or not intentional - are really funny.
