An aerophone

What you can do here
Move the keys of the aerophone listening to the sounds that come out of the pipes.


How it works
Moving the keys of the aerophone, you squeeze the bellows that force the air into the pipes. The sound in the pipe is generated as a result of vibrations of the air column in the body of the pipe. These vibrations are the result of friction between the air and the elements of the pipe in the slot. The shorter the pipe, the higher the sound.


Interesting facts
Croatian Zadar has sea organ with a width of 70 m. It consists of 35 pipes hidden in a stone body which also functions as stairs. Water and wind replace the bellows that force the air through the pipes. The length of the pipes has been selected so that the sounds produce a harmonious tune.
