 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... Around 1976 I bought a black record at my favourite musicstore Musicman, in Ghent(BE) where I was growing up at that time.

 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!)... and with a lighter string, lower... 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!)... and with a lighter string, lower...

 +Remark: just found out that 1m of 0.6mm diameter piano wire = 0.22grams; will re-calculate it all later sorry... I estimate with 6kg tension we would get approx 150Hz...

 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.

 +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):
