Keyboard aerophone

HOW

Move around the keys of the aerophone listening to the sounds that come out of the pipes.

WHY

By moving the keys of the aerophone, you squeeze the windbags which force air into the pipes. The sound in a pipe is created by the vibration of the air column in its body. These vibrations occur as a result of the friction of air against the parts of the pipe within its slot. The shorter the pipe, the higher the pitch.
