Susan,

Yes, I have done recording sessions. And 
most of them were not in studios (though 
some were) - but in concert halls, 
churches, sound stages - get my drift? 
And yes, lots of opportunities for drift 
in pitch. And there were times where I 
actually had to come in and sub for 
another tuner - where they had to leave 
- so who knows what the original tuning 
was like in terms of stretch, etc. And 
who says there is opportunity to "take 
your time" etc. - there are often 
engineers and others such getting paid 
union scale per hour - with overtime (as 
with the Boston Chamber Music Society), 
so a tuner fussing around with the piano 
when they are ready to record again 
ain't going to be cheerfully put up 
with... So yeah, you figure out where 
the piano is at, fix the "oinkers", try 
not to make too many severe changes if 
you can help it... That's what I was 
taught by experienced recording session 
tuners who called me in to sub for them 
- which is how I got into that line of 
work. If some people get to tune in 
climate controlled studios, well, that's 
a nice luxury. Check some album covers 
and CD jackets - and you'll see that a 
lot of recording is done outside 
studios, to take advantage of hall and 
church acoustics... Some of Peter 
Srekin's recordings come to mind...

The first time I ever did a recording 
session was at the Methuen Memorial 
Organ Hall (outside of Boston). It's a 
hall that was built especially to house 
a reconstructed 19th-century organ, with 
wonderful acoustics - which is why 
people like to record there - but no 
insulation whatsoever, against weather 
or against sound. We literally had to 
re-record every time a car drove by 
(it's on a quiet street, but cars do 
drive by occasionally). Pam Emerson 
tuned the piano to begin with, but the 
session ran way overtime and (being a 
mother) she had to leave. So I took 
over... The instructions I got from here 
is how I tuned recording sessions after 
that - as I describe above. And I got 
the same instructions from others 
afterward. After that I had occasion to 
tune in the Boston University Concert 
Hall after midnight - when it was used 
as a recording site - at the Skywalker 
Ranch sound stage here in California 
(which was used for recording by 
Harmonia Mundi, and I was subbing for 
the regular tuner who had to go to his 
daughter's birthday party) and at a 
bunch of small studios around here - in 
all of these places pitch drift was a 
concern. I wouldn't dare to use an ETD 
under those circumstances - staying with 
a gradual drift and fixing whatever 
stands out as a bad interval or unison 
is far the lesser evil than jerking 
everything back to where you started from...
