In poetry:

She noticed a small jet of smoke issuing from a hole near his head,
And if he'd lain a few seconds longer there he'd been killed dead,
But God had sent an angel to his rescue,
For seizing him by the arms his body to the air shaft she drew.

Till the can was full of doughnuts and the shack was full of smoke.

In science:

For example, dramatically lower P can be obtained by increasing the Q of the membrane resonances, beyond the mere Q ∼ 102 here, e.g. by decreasing the radii of the air holes (limited by losses).
Designing evanescent optical interactions to control the expression of Casimir forces in optomechanical structures
Thus the fundamental frequency of the sound from a pipe is determined by the effective length of the air column L, which can be changed by the player with opening some of the tone holes along the pipe.
Music in Terms of Science
Changing the length of the vibrating air column through opening or closing holes in the side of the pipe, as can be done by covering the holes with fingers or pressing a key which then closes the hole.
Music in Terms of Science
Row upon row of pipes of different pitch but of the same “timbre” sit on compressed air supply channels where pulling a given “stop” (in a “stop-channel” design) moves a wooden slat called slider such that the holes in the slider line up with the toe holes of pipes to admit the air into a given channel.
Music in Terms of Science
As the air enters the pipe through its toe hole on the bottom, it hits the sharp edge at the front causing the air to vibrate.
