-
The musician sends pulses of air down the tube which are reflected back from the open end.
-
The two types of pulse interact to produce areas of even higher pressure.
-
When a series of pulses are sent down the pipe, they interact with reflected pulses to set up a standing wave.
-
If the standing wave hits the pipe's resonant frequencies, or one of its harmonic frequencies then the pipe will vibrate to produce a sound. Some people would say that the sound is music.
