 For years, we have been listening underwater to fish, insects, streams/waves, and more unidentifyable noises using hydrophones. When we were discussing how to make a new kind of soundboard based on new ecological and technological possibilities, one of the things that came to mind were the use of strings and their natural resonances in the light of environmental sensing. Strings that resonate with the chaotic waterstreams might provide interesting sounds and time-based variations. Combined with a low consumption but far reaching transmitter from remote areas to receivers for network distribution may open possibilities for spatial representations as well.   For years, we have been listening underwater to fish, insects, streams/waves, and more unidentifyable noises using hydrophones.

 +Around 1976 I bought a black record at my favourite musicstore Musicman, in Ghent(BE) where I was growing up at that time. It was labeled "Obscure no.4: New and Rediscovered Musical Instruments" by Max Eastley and David Toop on Brian Eno's Obscure Records series. On the back there was a picture of Max Eastley's 'Hydrophone' design (no photographs). I liked the haunting sound a lot at that time, but of course the minimal drawing doesn't much explain the instrument... There was also a different 2-CD release (2010) with a compilation of Eastley's string instruments, but unfortunately the Hydrophone is not included for listening to...

 +As far as I remember, I did not encounter much strings & water installations afterwards. There were a lot of artists that inspired me though, like Glenn Branca's guitarboxes, which were extensively described in Bart Hopkin's Experimental Music Instruments magazine year 1 issue 3, unfortunately no archived or accessible online. The guitarboxes followed an ingenious resonance design, I saw/heard them in somewhere in the 1980s in Brussels, and they had the same mysterious sound. The interesting thing was that they pickups were situated behind the bridge so that you couldn't hear much of attacks and plucking on the strings. OK, but no water yet... 
 + 
 +Another inspiration for sure came from meeting Paul Panhuysen at the Apollohuis, Eindhoven in the 1990s. He made very particular long string installations, based on triangular principles. If I remember it well, he was using steel wire 0.3-0.6mm. Of course for the long strings you need to cope with quite some tensions and forces. And he was using special tunings. At the ZKM site you can also find a beautiful picture of the piezo attachment by Hélène Panhuysen. Just to give you an idea. Most of his fantastic work you can find on his original website (click work, then long strings and sound art). Still no water, I know...

-One needs a kind of driving force, which in our case will be unknown and variable, provided by the water streams. As an example, when using a 2m piano string weighing 0.01kg/m, with a 10N tension, one could hear 1580Hz (if my maths are right olala!)... +One needs a kind of driving force, which in our case will be unknown and variable, provided by the water streams. \\

 A natural water stream is per definition unstable, so we will get only chaotic oscillations occuring. That might prove a difficulty and will probably require dynamical tuning of the string, increasing and decreasing its tension.  A natural water stream is per definition unstable, so we will get only chaotic oscillations occuring.

-==== 3. The Prototypes ====+There are some easy tricks to find out the general speed of the stream, depth and width. Maybe they can be useful, and certainly nice to play with, for instance (but you will find a lot more online):
