In poetry:

And if he'd lain a few seconds longer there he'd been killed dead,

For seizing him by the arms his body to the air shaft she drew.

To see him plug a doughnut as he tossed it in the air.

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

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.
