When your husband is up inside the innards of a 1928 Austin universal wind chest, which is a large, walk-in, air-locked, pressurized box of reinforced boards that provides the wind to all the pipes mounted on its top, and your husband is 6'-3" tall, the one thing you definitely don't want to hear is,
"I crawled in here forward; I don't know if I can turn around."
Good thing he took a cell phone in there with him. He needed it to tell me, seated at the console, when to turn the organ on and off. When you turn that organ off, there are intermittent soft sighs as the air seeps back out of the very extensive wind system of the organ after the blower stops. It sounds for all the world like moaning ghosts, especially in a large, quiet, empty sanctuary after nightfall.
We were tuning until nearly nine o'clock. That organ is large enough that you could easily spend two or three full days tuning if you were to tune absolutely everything on it. It's a four-manual organ, with pedal, great, swell, choir, and solo divisions. The solo division is in a chamber one story up above the balcony, at the opposite end of the church from the console and main organ chambers, which are, standard Presbyterian/ Methodist style, front and center behind the altar. We used cell phones to assist with the tuning of the solo division, since there is no way someone sitting at the console can hear the poor soul up in the solo yelling "Next!" when it's time to hold the next key.
I spent close to twelve hours sitting on the organ bench, my feet dangling because I'm too short to rest them on the pedal board. (We're nice technicians, and do not adjust the bench unless absolutely necessary. Even then we put it back the way it was when we came.) Mad Musician spent the same amount of time contorting himself into the smallest and strangest of spaces, reaching carefully across ranks of pipes with his tuning knife, being careful not to "butt-tune" any mixtures.
A mixture rank has from two to five pipes that play together when you play one note on the keyboard. They're tons of "fun" to tune, since you have to block off all but one the pipes with pipe-cleaners, and tune each one to blend with the others. Mixtures are what give sparkle and shimmer to some organ registrations. For the mixture on the swell Mad Musician had me turn on the stop we were tuning the mixture to (the reference stop) then turn the reference stop off to tune the individual pipes of the mixture to the others.
"Butt-tuning the mixture" means to bump the delicate little ranks of mixture pipes with your behinder while you're bending over to reach across to tune something else entirely. Not a cool trick, and a good example of why ordinary lay people should not go poking around inside an organ chamber.
I'm just in awe of Mad Musician's ears. (Well, I like his behinder too, but hey, I'm married to him.) After many hours helping him tune, I can finally hear when two pipes are out of tune with each other, but it takes me a few seconds of listening and concentrating. He can hear it right away.
Fortunately, Mad Musician was able to repair what he needed to repair inside the Austin wind chest and extricate himself. I did not have to go in after him.
For a man who claims he's no good at dancing, he sure seems to be able to move around wonderfully in the tight and delicate of spaces of a pipe organ chamber.
