The article discusses the concept on the hydraulis or the water organ's sound production. It notes that the essential feature of the musical machine, hydraulis appears to be that air is supplied to the organ pipes at a uniform pressure and the air pressure can be stabilized in part by the use of water pressure. It presents a series of theoretical information concerning the process on how sound will be produced out of the hydraulic organ.
