[CAUT] Humidity Question

[Jeff Tanner]

Hi all,
We've had a humidity "spike" in our recital hall the last week or 10  
days.  Every one is screaming that the keys are clammy, fiddle  
fingerboards are clammy and bowhair "skids rather than grabbing the  
strings".  Yeah, yeah, yeah, the pitch of the piano jumped a few  
cents over last weekend, but nothing is screaming high humidity to me.

The "spike"?  We were up to a whopping 55% at one point, which by  
August standards would be a kiln.  But we'd been running in the upper  
30% to low 40% range fairly consistently until this "spike".

Question is, why is it faculty and students seem to notice  
condensation on the keys if it gets over 48% in February, but if it's  
75% in a studio in July, nobody mentions it?

I understand walking out of a much cooler, drier hallway into the  
recital hall, which has humidification/dehumidification that is  
actually working, there is a noticeable difference in the feel of the  
air.  But why is there a difference in condensation, or why is there  
a perception of clamminess now and not in August?

Thanks,
Jeff
