Barbara,

Hopefully you know the hall and piano well enough to have a good idea of
how it goes out - the tenor is the most variable in the majority of
pianos I have worked with.
=20
If you can get the hall to put the lights on for an hour (with the piano
on stage and open) before your first tuning, that is ideal.  Otherwise,
I would tune it about 1hz (~4c) sharp when cool (not cold), then talk to
the stage manager and tell them you need to touch up the tuning with the
piano in place and the lights on after rehearsal.  If the stage manager
balks at this, be firm - let him/her know that it is quite necessary.

On the 'hot' touch up, pay special attention to the octaves below the
temperament and into the bass, and work the unisons of course.

Hi all (especially Guy Nichols),
=20
Big concert on Friday.  The piano concerto isn't first on the program,
darn.  So......where should I put the pitch--preheated under the lights
or o' de natural?  If it helps, I tune before the rehearsal, the
rehearsal is mid-afternoon, orchestra breaks for dinner (piano gets
touched up), concert at 8 pm.  I know it doesn't take long for the
downward drift to take place, but how long does it take for it to go
back up?  =20
=20
I've found that the drift with the lights is normally 4 cents in the
tenor and treble.   Fortunately, the unisons don't go wild.

Thanks for your insight.
