Hydraulophone: Water spray jet as music controller

[kratanuva725]

Sounds like triangle waves, haha.

[CpnCommadoorColonel]

Whoa! O_ O

[rawritssami]

i don't understand where i would fine one. o_o

[eufralover]

cool

[biglumux]

que delicioso oir musica con agua... aqui nunca llueveeeeeeee

[sabin10]

sweeeet!!! I have to go to the science centre this summer. Only 10 minutes from my parents place :D

I'll have to show my mom this since she is a piano player.

[zer0odegrees]

is the hydraulophone played like the piano bc i can't see how a first time person know how to play it...

but this is wonderful, very cool

[brandonctl]

whoa amazing

i have that digital camera too

it's quite handy.

[jimmyjazz420]

so whos recording you recording buddy playing Pachel?

[Sweetbutdeadly666]

Why is there three minutes of nothing at the end of this?

[Luffy26]

Hey i wonder how much rhese things cost

[deaconproject]

really interesting .i feel like playing it know man

[rayofminneapolis]

WoW. This is the coolest thing in the world right now. For REAL. Who invented this. Who designed this one?

Ontario Science Centre in Toronto? IM GOING TO CANADA!

[wendy191]

can anyone kindly explain the physics principal how hydraulophones works?

[hydraulist]

Interfering with the flow of water out one or more of the holes forces it elsewhere inside the instrument to make sound. Actually all of the notes are always sounding a little bit, but changes in the resistance the water meets cause it to go elsewhere inside the instrument. Water, being a relatively non-compressible fluid, tends to give you a good range of musical expression even if the sounding mechanism is an inch or so away from where your finger is touching the water.

[eugenetswong]

@hydraulist So, for the 1 in front of the science centre, when you cover a hole, the water goes elsewhere. Does the water cause a thing to vibrate, like air causes an oboe reed to vibrate, or is it like a flute, in that the water vibrates, or what?

Sorry for asking, but I just don't get it. I read a few descriptions and the Wikipedia entry, but I don't understand still.

[Avelach]

Há registros de um órgão hidráulico, não me recordo se no Egito ou na Grécia antiga. Será que é esse instrumento aí, ou pelo menos ambos seguem o mesmo princípio mecânico?

[biglumux]

MUY INGENISOOOOOOOOOOOO

[delstons]

Very odd and cool. Thanks for sharing this.

[Pentence]

Nice i bet it took a long time to learn how to play on that thing.Very cool indeed.

[msbfd]

nah - anyone who can play a piano or synth by intuition rather than music lessons can pick it up (for slow stuff, of course) nearly at first sitting.

[hydraulist]

Yes, modern hydraulophones are easy to play. The guy playing the Bach piece had no prior practice... just walked over and played it after seeing it for the first time in his life. Newer hydraulophones also have a very light touch and no longer require tremendous physical strength and perfect-pitch hearing to play. But even modern "hydraulic assist" hydraulophones have alot of subtle forms of hydraulic expression, so that after many years of playing the instrument one can still learn more.
