Someone figured out a way to demonstrate that it's not "moving air" that causes a brass instrument to vibrate.

"Blow that thing!"

no.

"Vibrate that column of air!"

But it only works if you sway around while playing. If you stay still... no go.

Has been known for 50 years.

Better expression would be "energize that thing"

I'd wager that people knew this far more than fifty years ago, but didn't get credit for knowing it because they didn't publish it in a peer-reviewed journal.

To this day (as an example of people embracing one of millions of things that are not so) - there are still people who believe that brass musicians create the sound by using air to force their lips apart - causing their lips to quasi percussively beat against each other (they even believe the same thing in regards to tips of single reeds against mouthpieces (yes they themselves play #3 and #4 stiffness reeds) and - magically, somehow - the ovaled away from each other tips of oboe and bassoon double reeds somehow managing to hit against each other).
To demonstrate otherwise (brass playing), I've had people consciously close their lips and then blow (with no success, of course - other than start/stop annoying intermittent noises). Of course, they can't produce the sounds they normally produce without forming their "embouchure" (which supports an oval-shaped vibrating open area in the center of their lips - however large or tiny, depending on the frequency). They claim that cameras prove them correct, yet the cameras have to be placed mouthpiece cups well away from the throats of the mouthpieces, video recording the lips' opening at an angle shows the vibration (even in slow motion) it still doesn't record the very center of the lips totally closing (as it doesn't). Of course, today there's AI, whereby most anything can be "proven".

BREAKING NEWS:

Trumpet mouthpiece maker brings to market new line of inner-mouthpiece membrane and noxious gas exhaust modifications with complimentary heavy weight valve caps.

Another way to say it is, "Make Bernoulli's principal at the mouthpiece and static wave theory through the horn work for you, not against you."

Yes, but in practice excellent use is of air is the fundamental prerequisite to a rich vibration.

Fat breath, fat buzz, fat tone.

A really well developed embouchure requires less air going past it to vibrate the same amount and as well (just as with a really well-made single or double reed).

I've observed a low brass pedagogical trend BACK towards talking about refining embouchures rather than (nearly exclusively) the "air air air" thing (which seemingly was popular for brass teachers to - again - nearly exclusively emphasize for some of the recent past decades). Of course air is needed, because it's the only way that we can get our lips to vibrate, but our lips need to vibrate beautifully rather than just "a lot", and - when they vibrate beautifully - we don't need extra deep cups mouthpieces with extra large throats to mask a mediocre quality vibration.

...I'm just going to say this stuff without using the word "maybe" or "perhaps" in front of it: (I'm old and senile, so I can get away with it.)

Amazing players - who can play long phrases - don't develop their lungs to do that; they develop their embouchures.

Also (messing with mouthpieces for years, now)... this trend to offer models of mouthpieces with very large (ex. 8.5mm - 9mm) throats... This doesn't help much of anything, and it wastes a lot of air (that we could otherwise use to finish out phrases, or to hold out these loud low fermata notes - whereby music directors really don't understand what they're asking us to do).

In regards to the nonsense and misogynist comment: I'm not taking the bait.

If you have ever been around a torch, they are not silent. Not being there I can only speculate, but I would guess that a part of the sound of the torch (sort of white-noise-ish) has found the resonant frequency of the pipe. So from my point of view, there IS a sound going into the pipe, from the torch.

There he goes flapping his lips about this again!
