Hi,
I learned many decades ago when I played horn a lot that you tune after
your instrument is warmed up so the pitch will not change as you are playing
through an entire piece. Instruments will reach the temperature of the warm
air that is blown through it and it will not go higher than that
temperature. Also, if your are part of a group and you are counting 30
measures of rest, you always bring the instrument to your mouth and gently
breathe into it to get the warm air into it before your play your first
note.
