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 in contact with the flue, and the shotgun mic (which is aimed 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 crossfaded into contact mic - the latter revealing the reverberent/harmonic effects of the slinky, as well the articulation of resonances. Whilst most of the resonances are derived from the flue/slnky combo, I’m fairly certain the network of stretched wires has 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.
