Abstract:
The Pipe Organ: The pipe organ has been around since the third century BC. The pipe organ originated from the hydraulic organ (Hy-draulus), whose wind source was created by the pressure of displaced water in a sealed container (Randel, 1968: 583). The invention of the organ is credited to Ctesibius of Alexandria around 246 BCE. He invented the hydraulis, a mechanical flute whose water pressure regulates the wind pressure (West-field, 2000).
