Cloud Triptych: an exploration of stochastic movement between discrete musical behaviours by Simon Cummings A thesis submitted in partial fulfilment of the requirements of Birmingham City University for the degree of Doctor of Philosophy Birmingham Conservatoire Birmingham City University November 2016 S. CUMMINGS, Cloud Triptych: an exploration of stochastic movement between discrete musical behaviours 2 Abstract The primary objective of my compositional research is to create perceptible, large-scale musical transformations. To this end, my research project was to compose a series of works employing algorithmic techniques of my own devising, specifically designed to map stochastic processes of movement between epicentres of discrete musical behaviour. The processes are codified in and realised by bespoke computer programs that generate the resultant musical material. This material is then interpreted, modified as needed and finally notated as a score. The implications and validity of these processes are thereby tested in the compositions. The specific focus of my research is music for acoustic instruments. The portfolio includes a principal work, Cloud Triptych, and five preliminary pieces for smaller numbers of players, exploring processes that generate portions of material to be incorporated into larger structures as well as complete compositions. An important part of this exploration was the integration of both computational and intuitive materials, and the extent to which computational models can effect an embodiment of my compositional practice, thereby simulating musical creativity. In each of the compositions the different aspects that make up any musical behaviour – such as rhythm, pitch, articulation and dynamic – are treated as independent parameters that together comprise the whole. As such, they are scrutinised and developed both on their own terms and in their role interacting with each other within larger musical entities. The central role of behaviour, and the way it can serve as a discrete epicentre of stable musical focus, is explored in several ways, abruptly alternating between contrasting behavioural states as well as various kinds of transition and transformation. The goal and outcome of this research was the composition of the extended large orchestral work Cloud Triptych, which lasts approximately 28 minutes. This was created using an extensive piece of software of my own design, CloudCube, that both encapsulates and greatly expands the computational outlook of the preliminary works, in so doing approximating closer than ever to an embodiment of the diverse aspects of my compositional practice. As well as the scores of the six compositions, the portfolio contains this 25,000-word commentary explaining the creative and technical processes I have developed, and discussing their implementation in the compositions, along with two accompanying CDs.

Special thanks to my supervisors: Howard Skempton, for having the loosest possible interpretation of a two-hour tutorial, the uncanny ability always to locate salient points for discussion, and for sharing quantities of wisdom that will take me years to unpack and understand. Peter Johnson, for convincing me that my work had the potential for further investigation, and for being the best academic mentor and proof-reader I’ve ever had. Extra special thanks to Herb, my beloved little cat, whose omnipresent company kept me from ever being alone. I would also like to express my sincere gratitude to the following people: Christopher Best, for being there at the beginning (the actual beginning) and for ongoing support and friendship. Paul Berg, for sowing the seeds of method and technique that would prove the most important of my compositional life. Stephen Thiselton, for saving the day more than once, and for helping me to apprehend and solve various elements within CloudCube. Michael Finnissy, for embodying an impossible combination of challenge and optimism, and for consistently asking the questions no-one else ever asked. Richard Causton, for countless, infinitely patient and encouraging conversations, and above all for helping me – finally! – to learn how to play. I dedicate this Ph.D. to my wife Anna, whose love and support has been and continues to be the one constant parameter in a landscape of perpetual transition and change. Without her this research could simply never have happened.
