Music of Wires – part 2

This diagram & idea deserves its own post (thanks heaps to moongold for sharing!) – its a great site worth further investigation!

I can tell you right now, if I had followed in my Dads footsteps I would own a farm by now, but I also know my own character too well & if I had, all the fences would be like the one above. There was a great story in the rural area down south where I grew up of a slightly nuts proto-farmer who bought a farm there & when he did his fencing it appeared all the fence posts had been installed upside down, ie all the pointy bits were pointing skywards! No one had the heart to go dig up a fence post to find out if infact he had just decided to install the fence normally & then sharpen the exposed ends for some reason that escaped your normal farmer, but I totally enjoyed the idea of eccentric farming…. Ditto for someone who would build a jetty like this one:

It would seem inspired, but as you started to get dizzy when returning home with a dinner of fresh fish you would realise it was more creative than practical!
Land art, or environmental art (or whatever it is ‘correctly’ labelled by academia) intrigues the hell out of me, especially if it engages the sonic sense. So please do reccomend me the most interesting & inspiring environmental sound art you’ve either heard of (or preferably experienced) so I can add it to my future travel agenda…

Music of Wires

When I was a kid there was a fairly corny ad on TV for some kind of drugs for sheep (drench) that featured farmers playing a tune on a wire fence & after a bit of a search I managed to find it on youtube, so for a bit of backstory & nostalgia check out this classic bit of New Zealand advertising from 1994:

Somehow I think the ‘creatives’ who came up with the concept for that ad might have heard of an Australian artist by the name of Alan Lamb, who has been making incredibly evocative music using lengths of steel wire as the main instrument since the 1970s. For some aeolian sound works he has used wire up to a kilometer in length (played by the wind & recorded using contact mics) while more installation type projects have involved shorter lengths played using a bow…. Heres a quote from ABC Adlib:

“The natural frequencies of the wire are determined by the integer harmonics of the fundamental. In very long wires such as telephone wires, which are also very thick the fundamental is well below one Hertz. Thus only the higher harmonic frequencies fall into the auditory range. The very high harmonics become so crowded they cease to have discrete frequencies but rather tend to beat together, creating second-order frequencies of lower pitch. In effect the relationships to the fundamental are lost and it becomes more useful to consider the length of the wire as a family of interacting segments, each with its own fundamental within the auditory range. The leads to an understanding of the vocal-like quality of wire music in which the sound is made of numerous ‘voices’, each competing for harmonic dominance.”

In this interview at Noyzelab he discusses some of his recording techniques: “I use ceramic piezo-electric elements from record player cartridges and fix them directly onto the wires. The method of fixing them is an art in itself and there is no single best met hod. Rather, different conditions require different methods, which are established by trial and error. The object is to obtain a satisfactory frequency response right across the auditory spectrum, and this usually requires one or more stages of filtering, equalisation and amplification before the signal is fed into the tape recorder. The ceramic elements are very small and do not appreciably affect the wire’s vibration, nor do they present a large profile to the wind, thus wind interference is kept to a minimum.

“The placement of the elements is very important, as is clear from a further look at the physics. The vibrations of most interest are generated in the transverse plane of the wire. These are not simply `back and forth’ vibrations but planar ones characteristically describing circles, elipses and higher order paths which can be reduced to two vectors in the orthogonal transverse axes. Thus two elements placed at right angles around the circumference of the wire will transduce each vector more or less independently. When the output of each is sent to the right and left ears the sounds are perceived as being generated along the right-left axis, in the same way as stereo music from audio equipment. However, with the vibrating wire, it is possible to go further. By separating the elements about a meter along the length of the wire, the phase separations of the longitudinal component of the vibrations can be detected and these are perceived along a depth axis; that is, near to far. Other more subtle effects also contribute to an illusion of depth and height. Thus, by placing the elements correctly, it is possible to generate a three-dimensional stereo-acoustic image of such fidelity that the music sounds as if it is filling the greatest of concert halls .”

Fascinating! Here are a few audio examples from some of his work available on an album called Night Passage first a short piece from a 13 minute track titled Last Anzac, recorded in 1983:

Also from the same album, the next two excerpts are from a piece titled ‘Meditation on Spring’ which was recorded at a festival in Kobe, Japan to commemorate the opening of the world’s largest electron accelerator. Besides producing sound by natural wind, Lamb actually “plays” this instrument by bowing it with a two-metre long bamboo bow strung with nylon. The second section has some of that vocal quality he mentioned above, the resonances almost reminding me of Tuuvan throat singing!

Another artist who has gained a reputation for creating music using wires is Alistair Galbraith, a NZ musician with a considerable history in underground music and who in 2006 was recognised as an Arts Laureate, a brilliant peer-driven awards system where artists are recognised for their long term commitment to arts. Along with artist Matt De Gennaro he has employed long wire perfomrances in site specific art galleries, working in complete darkness. In this interview from 2000 he explains a little of their modus operandi: “Performing only in darkness wakens every other sense than sight. The fact that the sound comes from all over the building rather than from the wire itself is more obvious when you’re blind. You feel inside the sound rather than peripheral to it. What we look like doesn’t matter, how we technically achieve the music is incidental, you only get the sound….. the sound of the wires is the sound of the building. It’s necessary to attach the wires at resonant, preferably hollow points in the building’s structure. We found that each of the art galleries in New Zealand sounded different. In Dunedin we installed two wires that were around a hundred feet in length, which gave us the lowest note we’ve worked with yet.”

Rather than bowing the wires, they use rosin on their hands & “we invited our audiences to play the wires at the conclusion of each performance – it certainly take a little practice to coax an even tone. It’s similar in technique to rubbing rims of wine glasses. I discover more and more strokes and pinches that call harmonics and squeals each time I play…”

Here are a few excerpts from their album Wire Music

Of course sound designer Ben Burt is infamous for recording the sound of hitting guy wires back in 1976 & manipulating them to become the sound of Star Wars laser beams, check the photo in this article and also here

A while back I was out recording winds during a gusty storm and went up to the wind turbine in Brooklyn here in Wellington & managed to record these sounds using a contact mic:

Ever since then I’ve been meaning to visit another location in Wellington where there is a huge antenna with high tension guy wires that are easily accessible… sounds like a mission for after we finish this mix! Heres the location I mean:

Kelp/Tentacle sounds

Ok, as promised heres a couple of kelp recordings from last night… The results were good & got better as the session went on, mostly because the backgrounds got quieter… After having a good listen i realised some of the freakiest sounds are actually very quiet sounds – bits where the kelp is sticking to the ground & sliding etc so I decided i will get some fresh kelp & do a late night session on the next quiet windless evening…

And if security or a passing police car decide to come visit I’ll make sure I leave the mics rolling!

“I have two suspects flagellating some kind of alien looking sea creature in a carpark. I am going to investigate, over!”

Recording Tentacles…

One of the main challenges with the film we’re working on at the moment is creature sound design…. Apart from creature vocals I’ve been working on movement & as these particular creatures have tentacles I’ve been trying various approaches – using mud recordings, various plant material etc but yesterday I had a spark of inspiration to try recording some kelp/seaweed & as it was such a beautiful summers day I was desperate for an excuse to skive off/i mean do some work at the beach so I grabbed a bucket, the record kit & headed off for a drive around the South Coast from Wellington. It is one of the best things about this little city; within 15 minutes you can literally be in the wild! And its my excuse for owning a 4WD, because you sure need one to get to this place (or a few hours spare to walk)

There was plenty of kelp but it was so hot that it was impossible to get away from cicadas… I had kind of suspected that would be the case, hence the bucket, so I climbed down on the rocks & managed to break some slimey long pieces of kelp off… And sheesh it is hard to break – its seriously strong! I also took a broom as figured I would need something to try & entangle the kelp – either that or go for a swim & swimming in kelp isnt my idea of fun! Anyway I managed to drag some kelp up on to the rocks & proceeded to break through it by hitting it with the broom… About this point some tourists came wandering along & asked what we were doing… ‘ah we’re collecting kelp to make sounds for the tentacles on a monster’ ‘for a movie?’ ‘ ah yes!’

There was no way in hell I was going to throw slimey smelly seaweed around in my studio so this evening I waited until most everyone had gone home & set my mics up outside. I hadn’t really thought about it, but a neighbour came wandering along & once he realised what I was about to do offered me some rubber gloves (he does prop building etc) and in hindsight, man was I grateful!

I recorded about half an hours worth of material, slithering & slapping the kelp down on concrete, and shaking the daylights out of it. The sound seemed like a cross between rubber & leather, except it also had a wet component to it – creepy! But the best material was when I was throwing pieces around that had multiple tendrills… I’ll upload a few bits tomorrow once I’ve loaded it up & sifted through it. Will definitely be putting some of this through the Doppler plugin too!

A fun day at the office!
