Graham Dunning creates sounds and rhythms by cutting up vinyl records, and having them trigger a variety of sources. Including; masking records so only discrete sections are played and looped (sampling), triggering synths via audio trigger (sequencing), and triggering mechanical percussive instruments (automated instrumentation). It’s essentially a rotating disc approach to tangible sequencing.
The assemblages seem to refer to Nam June Paik’s Random Access (Schallplatten-schaschlik), 1963/1979, which also featured moveable pick-up arms and vertical stacking of layers.
Wanda Gillespie – Higher Consciousness Integrating Calculator (with Sheoak)
I’ve been struggling to conceive of tangible ways to divide up loops. I have been vexed by the notion that sudden leaps across time do not seem relatable to our lived experience of the world. Although we have become accustomed to the once-jarring results of moving-image edits, what sort of tangible tool might we be able to relate with such non-linear editing processes? It must of course be responsive as a performance tool as well, so scissors and sticky-tape are out! Today I realised it is essentially slicing and re-ordering units of time. Then I realised we do at least have a way of conceptualising that – mathematics. The problem is this is still an abstract concept. I began asking myself what ways we interact with mathematics tangibly, and began considering the past, since the earliest technologies are often more tangible. Then, before I even realised what I was searching for, an image came up of this work by my friend and artist Wanda Gillespie. Duh! The ABBAcus!

This clip describes the re-production of sound on films, using photographic processes. Sound waves are converted to varying voltages, which affect varying amounts of light, which is then projected and photographed onto the films optical sound track. This is how motion pictures sound tracks have been reproduced in cinemas right up till the 21st Century, hence printed digital sound tracks have become more common.
Here Soviet composer Arseny Avraamov draws wave forms with paint on paper and then films them onto the optical track with amazing results.
Godfried Toussaint writes this neat paper on transcribing and generating African music rhythms via Euclidean geometry. Euclidean geometry is taking a set of simple, known elements and producing new elements from these. Applied to music he devises algorithms to generate permutated rhythms.
Euclid was a great Greek Mathematician from Alexandria.
