This week marks four years since I started Oscilloscope, a monthly event focusing on experimental electronic music. I’m currently writing this as Wales in under lock-down due to the Covid-19 pandemic and as such, any form of gathering is impossible.
Over the last 4 years we have been completely voluntary and survived on donations of time, energy, talent and even sometimes performance space. It has been an amazing experience. With a growing team of organisers, an supportive and articulate audience and performances over 50 different artists from at least 12 different countries producing genuinely world class work, I am truly humbled.
I could go on singling out highlights and kindnesses, but that would seem to neglect those that did not get mentioned, and perhaps I will return at a later date to update this blog and expand on some of those memories. However at this stage I think that the double bill of streaming that was put together with next to no budget and a lot of goodwill for the anniversary double bill on the last day of June and and the 1st of July 2020 speaks for itself.
Thank you to all in these videos of the two live streams from 30/6/20 and 1/7/20; but also a massive thank you to all those involved in the 4 years leading up to them.
Stay safe and enjoy!

It is common for composers to consider their work through a number of dimensions or axes; examples of which can be found in fugue technique, Whishart’s lattice model (Wishart, 2002) or more extremely, embodied throughout the methodology of 12 tone serialism (Schoenberg and Stein, 1950).
This planar thinking lends itself to the invention of various compositional techniques, on a simplistic level running variables in in retrograde fashion through to the nested recursion of the Art of Fugue (Bach, 1750) and Markov Chain compositional techniques (Roads, 2000). This is often linear, looking at a set of pitches or rhythms; interrogating and manipulating a stream of data points. From there it is only a small step to link extra information to this data. For instance, at a given time a certain note could be played at a specified volume by a given instrument (Boulez, Cage and Nattiez, 1999). Thus, in computing terms we arrive at a two-dimensional array of data, something potentially very close to a square if you were to tabulate it.
With the addition of other data and relationships comes the opportunity for higher dimensions within this array, popping an extra axis into a cube, followed by a tesseract, up until such points as it would be difficult to perceive within an audible work.
What if, rather than dealing with data points the composer was able to manipulate the dimensional space of the larger work?
Precession is an exploration of these ideas. It draws on the Pitch Volume Timbre space defined by Wishart but folds in one side of the ‘cube’ to form a pyramid space. Working from the assumption that pitch is mapped to x volume to y and timbre to z notes can be placed anywhere within the body of the pyramid. This simple translation brings a deal of creative perturbation to the system, as when any datum is near the apex of the pyramid (z axis) its potential placement within the two remaining axes (x,y) across the square base are several limited.
Where this becomes especially interesting is being able to roll the pyramid like a die within compositional space. If the view point remains fixed with x for pitch etc. any movement of the pyramid re-voices the notes therein, potentially in strikingly different ways. Thus, phrases are cast and re-cast within the rolling die of the shape causing processionary transformations of the material.
