Yep you use more air on a flute than any other instrument I think. When I was playing bassoon, I couldn't believe that - especially as I got so lightheaded from playing it but ... apparently its true

Ah yes, the double-reed light-headedness

I've blacked out on a few occasions when I was playing standing up under pressure.
You actually use a lot less air on double-reed instruments, to the point where you actually don't use enough of it.
The light-headedness is caused by a build-up of carbon dioxide in the lungs, and breathing in again just makes this worse!
When working out your phrasing, you not only need to work out where to breathe in, but where to breathe out as well.
After all, how do you expect all that air you're pushing towards the reed to escape through that tiny aperture?
This is probably also the reason we have a reputation for being ever-so-slightly ODD.
