The air column vibrates at a resonant frequency; the pressure wave travelling back to the mouthpiece forces it closed (or nearly so) a positive feedback scenario. Harmonics (partials) are re-enforced by the pressure wave - only those of an integral multiple survive (since they must exist within the fundamental - the end nodes of the fundamental and end nodes of the harmonics have to be coincident - think of a rope tied at one end and the other in your hand - you can have an integral number of "waves" if you move your hand back and forth, but trying to get a non-integral number doesn't work - the wave dies out).

The sound is created by a vibrating air column - it directly causes a sound wave (direct couple - air to air) . Non-wind instruments (such as string or percussion) cause a medium other than air to vibrate (indirect couple - vibration to material to air).
