Dr Roger Mills


Dr Roger Mills is an internationally recognised musician, composer and writer whose practice and research focuses on Internet music making, improvisation and sound design for radio, stage and screen. Credits include sound design for multiscreen cinema film Hindsight - Ignition Films (UK), the sound score for BAFTA award winning dance theatre performance At Swim Two Boys by Earthfall (UK), and a Golden Eye award for his multi-stream contrapuntal radio performance Idea of South. A selection of his sound design and musical compositions works were featured at the Third International Soundscore Exhibition as part of the Prague Quadrenniel (2011) and at the Gormley to Gaga, UK Performance Design Exhibition at the V&A, London (2012).

Recent work includes the sound score for flow#1-3#flie├čen an immersive multiscreen animation by the tranSTURM collective exhibited at the Galeries, Sydney, for VIVID2016, and the acclaimed studio album Mirror Image by his duo Nada 2015.

Roger is the musical director of the internationally acclaimed Internet music ensemble Ethernet Orchestra, which informs his research of intercultural telematic music making. He is an associate researcher at the Creativity and Cognition Studios in the Faculty of Engineering and IT, where he researches telematic interaction in networked and digitally mediated environments. He has written numerous conference papers, journal articles and book chapters on this subject and is currently writing a book on how cross-cultural musicians negotiate the creative telematic experience.


Roger has had a twenty-year career as a musician and sound designer. Alongside his academic work he continues to work in the field.

This article is an amalgam of the online presentation given by the author to the Cyposium, of Cyberformance on the 13th of October 2012, and continuing research of cross-cultural interaction in networked improvisation. It describes the analysis of 2 case studies of tele-improvised performances, illustrating the pervasiveness of conceptual metaphor in structuring networked musician's perception of causation in improvised musical interaction. The analysis is achieved through a multimodal analytical framework that examines instances of musical expression and interpretation from case study audio-visual recordings, and transcripts of musician's reflective experiences. The framework blends a Social Semiotic theoretical perspective with ideas from the related field of Cognitive Linguistics in examining experiential meaning potential in melody, harmony and rhythm, and the image schematic structuring of musician's perception in networked improvisatory interaction. While these terms will be described in further detail, the analytical value of this methodology provides a comprehensive understanding of the musicians' cognitive experiences, including their conceptual approaches to, and interpretation of musical components in improvised interaction, and the manipulation sound qualities to affect causation in improvisatory exchanges.


Mills, R.H. 2014, 'Flight of the Sea Swallow: A Multiimodal Approach to Examining Collaborative Interaction in Networked Music Performance', Proceedings of Conference of Interdisciplinary Musicology, Berlin Germany, pp. 1-6.
Understanding the technical and creative complexities of networked music performance provides the starting point for the analysis of the 2014 Flight of the Sea Swallow collaboration between networked musicians in New York, USA, Sydney, Australia and Braunschweig, Germany. Performers interacted remotely by navigating a 3-D audiovisual environment with wristbands containing accelerometers, visualised as animated hands within the virtual space. Heat and light sensors in each location generated data that was visualised as coloured lighting states within the physical performance space, reflecting those characteristics of the dispersed performers sensate environments. Drawing on multimodality, with its focus on the construction of meaning across multiple communicative modes, this paper examines the relationship between performers dislocated, technologically mediated interaction and the ways in which this shaped their improvisatory musical experience. The analysis examines the interplay between different modes of action, demonstrating the role that the body plays in the performer's relationship to the technology used and conceptualisation of their creative networked engagement.

The evolution of networked audio technologies has created unprecedented opportunities for musicians to improvise with instrumentalists from a diverse range of cultures and disciplines. As network speeds increase and latency is consigned to history, tele-musical collaboration, and in particular improvisation will be shaped by new methodologies that respond to this potential. While networked technologies eliminate distance in physical space, for the remote improviser, this creates a liminality of experience through which their performance is mediated. As a first step in understanding the conditions arising from collaboration in networked audio platforms, this paper will examine selected case studies of improvisation in a variety of networked interfaces. The author will examine how platform characteristics and network conditions influence the process of collective improvisation and the methodologies musicians are employing to negotiate their networked experiences.

Maturation of network technologies and high-speed broadband has led to significant developments in multi-user platforms that enable synchronous networked improvisation across global distances. However sophisticated the interface, nuances of face-to-face communication such as gesture, facial expression, and body language are not available to the remote improviser. Sound artists and musicians must rely on listening and the semiotics of sound to mediate their interaction and the resulting collaboration. This paper examines two case studies of networked improvisatory performances by the inter-cultural tele-music ensemble Ethernet Orchestra.It focuses on qualities of sound (e.g. timbre, frequency, amplitude) in the group's networked improvisation, examining how they become arbiters of meaning in dialogical musical interactions without visual gestural signifiers. The evaluation is achieved through a framework of Distributed Cognition, highlighting the centrality of culture, artefact and environment in the analysis of dispersed musical perception. It contrasts salient qualities of sound in the groups collective improvisation, highlighting the interpretive challenges for cross-cultural musicians in a real-time `jam session. As network technologies provide unprecedented opportunities for diverse inter-cultural collaboration, it is sound as the carrier of meaning that mediates these new experiences.

Diffusion contemplates the memory of water as metaphor for the residue of the toxic chemicals that have been dumped and continuously leach from the soil into the Parramatta River, moving up and down stream with the rain and tide, the industry and transport. A sound and light installation that spits, pulses and glows as the otherwise silent underwater sounds reveal the ebb and flow of the water and agitate pollutants that move within. Memory Flows is an ongoing and distributed media art project of the Centre for Media Arts and Inovation funded by the Inter-Arts Board of the Australia Council for the Arts. It was featured as part of the Sydney Biennale affiliated exhibitions.
