Pump music

Pump music

Intro
It costs you a little energy, but then you get a beautiful tone or even a melody. If there is sound to come out of the flutes, the air particles are pressed together in the area. The air pressure, there is increasing.
The compressed air surrounding the particles collide with particles in the air and release their energy by.

What is happening?
By pushing down the plunger of the pump you pump air into the flute. Air flowing past the lip of the flute, is swirling and let thereby vibrate the air in the pipe. The length of the pipe determines the pitch. The material of the flute and the details of swirling determine the tone.
