Simply by blowing air across a reed inside it and covering different holes to produce a certain pitch.
There is quite a bit involved in producing sound with a flute. I suggest the following links:hubpages.com/hub/flutehttp://www.markshe... you want to learn more about the physics of a flute:phys.unsw.edu.au/music/flute/Hope this helps! :D.
Flute produces its sound from the flow of air across an opening. The sound on a flute is produced by blowing quite a lot of air over the hole on the mouthpiece. Flutes have an oval hole over which you must blow.
But to do this you must have the right mouth shape, the shape used for spitting rice is appropriate. Then you blow lots of air over the hole. If you blow into the hole, no sound can be produced.
But you must blow lots of air, because some of the air escapes when blowing across.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
