[pianotech] Fork and piano temp. and pitch

[Mark Schecter]

Absolutely true, and part of my point. I'm confronted with the situation 
fairly often that I have to tune a piano in a storage room before a day 
of rehearsals, leading to an evening concert. The temperature range is 
often 10-15 degrees, sometimes more, and that is enough to require 
thinking about "Where do I want this piano to be later? And how will I 
get it there?" I admit that my precompensations for anticipated drop are 
guesstimates, but at least I'm trying to anticipate, rather than blindly 
setting it at "440" as if that's where it will wind up.

The question of just how sensitive the users are to slight variations in 
pitch figures in, too, but maybe in a separate thread.
