Wols,

As a piano/keyboards/bass/guitar player here who has only played with an 
"orchestra" for high school musicals many moons ago, you have me 
wondering now:

From what I thought happened, the oboist tunes to the piano if one is 
used or to a tuner otherwise.  From that point, I assume all the 
woodwinds can match the A and tune themselves.  Strings usually have an 
open A, and then they can tune the rest by fourths/fifths.  When and how 
do the brass typically get their reference pitch?
