How to play a high note airlessly?

[kmche12]

I can play up to high G without air sound, but when i get to A , B, & C, i can hear so much air.. my teacher told me to breath with tummy, does it help to sound airlessly?

Your teacher obviously thinks so. Breath sounds are often caused by an unfocused airstream (incidentally, you need a more focused airstream for the third and fourth octaves than for the first and second). You'll want to work on your breath control (which I'm sure is what your teacher was getting at with the tummy breathing) to eliminate most of the wind noise. Keep in mind that depending on who you listen to, wind noise may not be a big deal. I sat next to William Bennett (who taught Galway), and next to him there is a ton of air noise, but out in the audience, it's a pure, beautiful tone. Orchestral players often have air noise (the extra air helps them project), but soloists do not (because of the proximity of the microphones in recording sessions). Some headjoints also contribute to air sound, and it may be that you have one like this. Drelinger (and other makers) have developed their own solutions to this because it is a problem for some people.

You can also try really dropping your jaw to make your apurture (sorry I know i mispelled it) "taller" (from top to bottom). It will make the sound bigger, and would probably help.

Propper breathing will help the quality of your notes. If you have "breathy" high notes then you should change your lip position.
With low notes you should bring your mouth position back so that your cheeks are sticking out kindof like you are smiling! With High notes your lips should be almost sticking out and you should have a smaller hole so there is a more focused air stream (so that you look like you are trying to kiss someone over the mouthpiece of your flute)
As you get higher then the airstream should become more focused. This will help with the breathy sound and with tuning. (hopefully)
