The water organ or hydraulic organ (Greek: ὕδραυλις) (early types are sometimes called hydraulis, hydraulos, hydraulus or hydraula) is a type of pipe organ blown by air, where the power source pushing the air is derived by water from a natural source (e.g. by a waterfall) or by a manual pump. Consequently, the water organ lacks a bellows, blower, or compressor.
On the water organ, since the 15th century, the water is also used as a source of power to drive a mechanism similar to that of the Barrel organ, which has a pinned barrel that contains a specific song to be played. The hydraulis in ancient Greek is often imagined as an automatic organ, but there is no source evidence for it. One of the oldest automatic instruments known is the automatic flute player invented by Banū Mūsā brothers in 9th century Arabia.

Famous quotes containing the words water and/or organ:
“We’ve only just begun to learn about the water and its secrets, just as we’ve only touched on outer space. We don’t entirely rule out the possibility that there might be some form of life on another planet. Then why not some entirely different form of life in a world we already know is inhabited by millions of living creatures?”
—Harry Essex (b. 1910)
“What we commonly call man, the eating, drinking, planting, counting man, does not, as we know him, represent himself, but misrepresents himself. Him we do not respect, but the soul, whose organ he is, would he let it appear through his action, would make our knees bend.”
—Ralph Waldo Emerson (1803–1882)
