I was wracking my head on the drive down to my mum's farm this weekend. I'd made plans to start building a much-talked about aeolian harp on the property using found materials and various bits and pieces I had lying around my home studio. I was (over) thinking aspects of resonance, wire lengths, fundamental tones, harmonics, etc and in between this I was also thinking about this week's challenge.  A couple of days work resulted in the MiddlePhone* (see pic and footnote below) and an outcome for this weeks Junto challenge.

I attached one end of a slinky to the chimney flue on the MiddlePhone, and the other to a tin can. I fixed a contact mic to the interior surface of the chimney flue and pointed a shotgun mic off into the distance. Hitting record, I stretched out the slinky/can and hummed an improvised melody into the can for about a minute.

In the recording you can hear two simultaneous recordings which have been mixed together: the slinky's contact with the flue, and the shotgun mic; which is fixed on my position with the stretched slinky/can. I've mixed the track so that you hear only the shotgun mic recording at first (w/peripheral sounds) and then gradually crossfade into contact mic; the latter revealing the reverberent/harmonic effects of the slinky, as well the articulation of resonances. Which most of the resonances are derived from the flue/slinky combo, I'm fairly certain the network of stretched wires have had some effect too.

The MiddlePhone*

Yesterday afternoon, I deviated dramatically from my original design plan for the aeolian harp; to such an extent that it resembled a completely different instrument - which you can see pictured in the track cover. It comprises of an old tallowwood fencepost jammed between the branch stumps of a Melaleuca tree. The post has thin wires attached to it which are tightened and fixed to the ground, as well as run over an oil drum and also connected to a chimney flue. The wind interplays with it discretely, but is most effective as a ridiculous percussion instrument. However, attaching contact mics to it reveals a variety of resonances and sonic perculiarities. More recordings of the MiddlePhone to feature in the near future!

Tristan Louth-Robins is a South Australian artist working principally in the medium of sound art and field recording. Ideas of sound and its signification are key elements in Louth-Robins' practice, traversing the space between the visual and aural his work is realised through the mediums of recordings, installation, visual art and performance. He is interested in sound and its associative implications - including its relationship to objects, technology, urban space, memory and the natural world. 


Since 2005, Louth-Robins has presented work in Australia and internationally as a solo artist, whilst also collaborating with artists, writers, researchers, musicians and performers. 

Working across a vast array of activities encompassing composition, sound design, installation art, field recording and workshops, his work has been featured in events such as the Adelaide Festival of Arts (2006), The National Regional Arts Festival (2012), Mildura-Wentworth Arts Festival (2013), Fairfax Festival (2013) and Adelaide Fringe Festival (2014); and selected works exhibited at galleries including The Australian Experimental Art Foundation (2009), SASA Gallery (2012, 2015), Light Square Gallery (2012) and FELT Space (2015). His audio works have been broadcast on radio including Radio National, Classic FM, The BBC (UK), Acoustic Frontiers (USA) and RBB (Germany).
