PERICLES vaulted the PERICLINE

Talker to my brother in law – a geologist – yesterday whilst out on a bike ride (interrupted to drop in to their flat)(thanks for the sherry and crisps! That’s what I call ‘a bike ride’!). He said ‘PERICLINE’ was a word. Indeed it is:

The Mendips are an example of anticlinal folds, recognised on geological maps by a concentric outcrop pattern with the oldest rocks at the core. The distinctively shaped variety of anticline that forms each of the Mendip Hills is known as a pericline.

So that’s it: Syncline / Anticline / Pericline

A TRIPTYCH: SYNCLINE – ANTICLINE – PROCLINE

[Ralph Hoyte posts] I am a Bristol-based poet, writer and producer of GPS-triggered locative media. I deal in the live voice – mine, or multi-voice set-ups, set, er, somewhere, somehow. I write, sometimes, ‘poetry’ (whatever that is), more often, ‘poem-scripts’, often heavily research/historically/cultural-historically-based. I deliver them  live, or through ‘locative media for the smartphone’, or through any other means to hand (such as Raspberry Pi powered sculptures responding to user input through touch or light). I often work closely with Phill Phelps, coder and audio-engineer, on the  technical aspects of such projects.

For step in stone I am working on a triptych of sound interventions which all feed off the same poemscript; SYNCLINE , ANTICLINE, AND PROCLINE.

SYNCLINE

come in numero 82 your time is up: the different bits of the autonomous megaphone assemblage

The poemscript is recorded (2 or 3 voices, probably my voice and 1 or 2 synthesized voices), placed on an SD card inserted into a mini-mp3 player circuit board, played back through a megaphone (it’s waterproof), whole thing driven by, essentially, a motorbike battery. There are 5 or 6 such autonomous assemblages. They are hung off the edges of the cliffs in ‘The Amphitheatre’. Each unit has a different ‘personality’. The SD card is loaded with poemtext, possibly ambient, and … silence. At any one time you get poemtext, ambient, or silence. Six of these doing that, each with its different personality, creates the soundwalk as you perambulate around the floor of the Amphitheatre (keeping well away from the walls!). I like serendipity. There will also be a nightwalk.

ANTICLINEWestdown map

A GPS-triggered soundwalk for the smartphone:  ‘pools of sound’ are virtually placed along the ‘figure-of-eight’ walk around Westdown Quarry (think that man on the TV add who stumbled across a red circle on the ground: when he stepped into it, he heard music, when he stepped out of it, it stopped. Remove the red circle. That’s it)   You download the app, go to Westdown and turn it on. When your phone encounters a pool of sound you’ll hear the audio for that ‘virtual red circle’ (and, no, it doesn’t need a network signal). Of course, it’s  more elaborate than that ‘red circle’ scenario: you can make the audio in the soundpools do different things; you can also, interestingly, ‘stack-up’ the soundpools, or overlap them. Who knows what happens when you overlayer 3 zones?

For starters, the word ‘procline’ doesn’t really exist (see, WordPress underlined it in red. It doesn’t exist), and, if it did, it’s not, unlike ‘syncline’ and ‘anticline’, a geological word. Never mind. Maybe I’ll rename them ‘syncline’, ‘synform’ and ‘syntax’. Whatever it’s called, PROCLINE is  going to be a gallery-piece consisting of (probably) a geological specimen drawer thing with 3 drawers. When you pull out Drawer 1,  audio channel 1 is activated; ditto 2, ditto 3. What you hear of the common poemscript depends on how many drawers you’ve pulled out/pushed back in, and in what order. To add another layer of serendipity,we may programme it so  the audio-files associated with each drawer are chosen by the mini-computer driving the whole thing. In the drawers may be … stuff, resonating with the quarries. So it’s visual and tactile and user-directed.

 

Photoshoot at Fairy Cave

A few of us met at Fairy Cave on Thursday for a photoshoot, equipment test and H&S walkabout with Martin Grass from Fairy Cave committee.  We had a glorious day of sunshine.  This had also brought rock climbers, who were already up rock faces in the quarry, when we arrived.  One of them – Terry Gifford – happened to have supported us via IdeasTap crowd funding, so it was a lovely surprise to meet him there!

We discovered that Fairy Cave is not only an area of SSSI for its renowned caves, but is also designated as SAC (a Europe-wide status) for its rare abundance of greater horseshoe bats – most evident in the winter months. Some caves were newly exposed through quarrying, although one was sadly removed.  When standing in parts of Fairy Cave quarry, we are standing in what was a vast ancient cave.
