It's perhaps worth noting that wind pressure can give carrying power to a stop's timbre - an attribute that's desirable/necessary in such a vast space.
Very informative, with a bit of humor thrown in. The relation of air pressure on pipe volume is something that many people probably don't think about, or they assume that the louder the volume, the higher the wind. You did a excellent job of explaining why that is not true. I'll have to remember this information when I go to order my next organ! Thank you for sharing, as always.
Oddly enough I have seen Pipe Organs for sale on " Market Place " recently but I do not have 10' ceilings or 1000 sqft music room oh well its on the when I win the lottery list . LOL
Yes! The logarithmic scale. It is louder, but not ten times louder, since it's on almost 10x the pressure- that's the point. You also notice that the meter said that the Mirabilis was softer than the regular Tuba!
@@cnagorka Due to the logarithmic scale of perceived volume, wouldn't a convergent sequence to a particular ratio constitute the "ideal" library of wind pressures for an organ? For example, say one built an organ with a Fibonacci Sequence of wind pressures - 1", 2", 3", 5", 8", 13", 21", etc. - wouldn't that (with appropriate voicing, of course) allow one to achieve a relatively "even" progression of volume? (I now realize that this comment is rather off-topic given that I was thinking more of flue pipes. Now I'm wondering how it works for diaphones, though...)
I build tube amps, have you seen the prices they are getting for those now, they are getting expensive. I try to use less costly tubes but still get good results.@@cnagorka
It does have some influence over the tone, of course, I just wanted to make the point that it doesn't work like flue pipes. I've never seen a skinny little french horn, for example. But I think it's used in large part to scale the organ for the room, larger resonators for larger rooms, within reason. Of course, you will ALWAYS find exceptions to this.

Absolutely. I oversimplified these things for the video.

I'm glad I saw your organ-encabulator video before watching this, now I know exactly what to order!
Very interesting, I've always wondered about these things!
Very informative video, tnx Chris as always.
Great video. Learning these details is very interesting.

Pipe organs are commodities which can be sold and traded like anything else, which surprises some people.
13:24 The Kimball tuba at 119dB is 6.3 times as loud (+8dB) as the 111dB trumpet in your hometown instrument.

Yes indeed --- and I still love that dual-triode shirt.

@@Kaiveran Same here for diaphones. I would like to build a wooden set to match the early Wurlitzer leaded open diapason that I have.
Nice shirt, which twin triode tube is it? Thanks for the new lesson on pipe purchasing.
As far as I'm concerned it's a 12AX7.

@@cnagorka or it could be a 12AU7, or a 7025, or a 12AT7, or a 5751, or a 12DW7, or a 12BH7, or a ……😆
What *does* the resonator scale actually do, then?
