MessageDon,

Thanks, for your advice.  That's how I'll do it.  This is my first =
season here and so far, the set ups and uses have all been different--so =
I've been learning how the piano reacts (no complaints *yet*-- thanks to =
the head's up I got in Guy Nichol's class in Nashville).  At my last =
gig, lighting wasn't an issue.  Oh, for those days!

There's no problem getting the piano pre-heated.  But since it's not =
first on the program and will be closed up and sitting off stage for a =
while, I wondered how the lag time would affect it.

Barbara Richmond

PS  How long does it take a hot piano to go back up in pitch?  (Not a =
joke, just a question.)

  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.

  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),

    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

    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.
