Not being a brass player, I find this suggestion difficult to understand.
Can you describe it a bit more clearly?  Do you blow across the "wrong" end
of the mouthpiece like blowing across a beer bottle?  What I cannot figure
is the idea of "inverting" the mouthpiece.  Aren't they the same all the way
around?  Do you mean "reverse" the mouthpiece?

Subject: Re: [Finale] OT: blowing air through brass instruments

This is not that unusual an effect for brass players. What composers
(including Ligeti) seem not to realize is that brass instruments are
designed *not to make noise* when you blow air through them, which
tends to defeat the purpose.

The proper way to get the desired effect is to remove the mouthpiece,
invert it, and blow the air thru the inverted mouthpiece across the
opening of the mouthpipe. The only caveat is you have to give the
player time to take the mouthpiece out and invert it. Any dynamic from
pp to ff is possible, but playing ff requires lots of air, so there is
no way for a single player to sustain a note for very long.
