Soma: live performance where congruent musical, visual, and proprioceptive stimuli fuse to form a combined aesthetic narrative Ilias Bergstrom UCL A thesis submitted for the degree of Doctor of Philosophy 2010 1 I, Ilias Bergstrom, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 2 Abstract Artists and scientists have long had an interest in the relationship between music and visual art. Today, many occupy themselves with correlated animation and music, called ‗visual music‘. Established tools and paradigms for performing live visual music however, have several limitations: Virtually no user interface exists, with an expressivity comparable to live musical performance. Mappings between music and visuals are typically reduced to the music‘s beat and amplitude being statically associated to the visuals, disallowing close audiovisual congruence, tension and release, and suspended expectation in narratives. Collaborative performance, common in other live art, is mostly absent due to technical limitations. Preparing or improvising performances is complicated, often requiring software development. This thesis addresses these, through a transdisciplinary integration of findings from several research areas, detailing the resulting ideas, and their implementation in a novel system: Musical instruments are used as the primary control data source, accurately encoding all musical gestures of each performer. The advanced embodied knowledge musicians have of their instruments, allows increased expressivity, the full control data bandwidth allows high mapping complexity, while musicians‘ collaborative performance familiarity may translate to visual music performance. The conduct of Mutable Mapping, gradually creating, destroying and altering mappings, may allow for a narrative in mapping during performance. The art form of Soma, in which correlated auditory, visual and proprioceptive stimulus form a combined narrative, builds on knowledge that performers and audiences are more engaged in performance requiring advanced motor knowledge, and when congruent percepts across modalities coincide. Preparing and improvising is simplified, through re-adapting the Processing programming language for artists to behave as a plug-in API, thus encapsulating complexity in modules, which may be dynamically layered during performance. 3 Design research methodology is employed during development and evaluation, while introducing the additional viewpoint of ethnography during evaluation, engaging musicians, audience and visuals performers. 4 Acknowledgments Firstly, I wish to thank my supervisors, Beau Lotto and Anthony Steed, for taking on my project, and for helping me through with the work presented in this thesis. I am further grateful to have been surrounded by very interesting people at the Lottolab. Without Lefkothea Andreou, Daniel Hulme, David Malkin, David Corney, Erwan LeMartelot, Martina Wicklein, Rich Clarke, Madi Boyd, Emma Byrne, Sam Walker, and Katherine Bash, the time spent working in the lab would have been far less stimulating. Many thanks are due to Nadia Berthouze, Nick Bryan-Kinns, Alan Blackwell, Marcelo Wanderley, Katherine Stevens, Nigel Jenkins, Olivier Ruellet, Mauritius Seeger, Mat Hourteillan, Alison Hardcastle, Anne-Marie Preston, Illi Adatto, Dor Wand, the members of Accretion and of the Gathering, for their invaluable advice and assistance towards completing the work presented here. I owe my gratitude to my family, without the support of which I would never have had the chance of writing these lines. And last but not least, Giulia! 5 Table of Contents Soma: live performance where congruent musical, visual, and proprioceptive stimuli fuse to form a combined aesthetic narrative .........................................................................................1 Ilias Bergstrom ............................................................................................................................1 Abstract ..............................................................................................................................3 Acknowledgments ..............................................................................................................5 Table of Contents ...............................................................................................................6 Table of Figures ............................................................................................................... 11 1.

Interactive Music Visualization – Implementation, Realization and Evaluation MASTER DISSERTATION Marco Filipe Ganança Vieira MASTER IN INFORMATICS ENGINEERING ORIENTAÇÃO Mon-Chu Chen Abstract This thesis describes all process of the development of music visualization, starting with the implementation, followed by realization and then evaluation. The main goal is to have to knowledge of how the audience live performance experience can be enhanced through music visualization. With music visualization is possible to give a better understanding about the music feelings constructing an intensive atmosphere in the live music performance, which enhances the connection between the live music and the audience through visuals. These visuals have to be related to the live music, furthermore has to quickly respond to live music changes and introduce novelty into the visuals.

Hoyt / University of Connecticut tal Media and Arts Association conference, addresses the notion that the Rejane Spitz / Rio de Janeiro Catholic University, Brazil nature of digital arts is to embrace the new technologies of the time while Kenneth A. Huff / Savannah College of Art and Design perfecting those of the past. As such, it tends to sit outside the margin of discipline, thus deifying boundaries within its own set of standards. This art form is complex and multifaceted, however, it embraces two distinct aspects that are currently, and will continue to be, characterized by flux and defined by the rate of change of technology. The first exists on the fringe of the art world, embracing, exploring, incorporating, and translating the new- est digital media for the given time. The second is the molding of yesterday’s digital “edge” into traditional art forms or into mature and unique works that often do not fit within traditional aesthetics. Regardless of whether the art includes older or newer technologies, digital media art sits outside of tradition. It is a lightning rod for new media and acts as a disseminator of language and implications connected with it. Although traditional boundaries do not apply, grounding in artistic practice does, albeit in flux. The iDEAs 07 exhibition not only displays art that goes beyond bound- aries, but shows work that does not even consider them as the art reflects a discipline that seeks to find its own foundation.

    Beyond Live Digital Innovation in the Performing Arts Executive Summary

    Research briefing: February 2010 Beyond live Digital innovation in the performing arts Executive summary The UK has in recent years undergone a digital revolution. New technologies such as digital TV, music downloads and online games are ripping up established business models. Last year, the UK became the first major economy where advertisers spent more on internet advertising than on TV advertising. This digital revolution has caused upheaval in the creative industries – in some sectors, it has enabled creative businesses to reach audiences in new ways that were unimaginable in the 1. The NT Live research forms analogue age; but in others it has ‘cannibalised’ their established revenue streams. In all cases, part of NESTA’s wider study, led by Hasan Bakhshi and digital technologies have produced seismic changes in consumer expectations and behaviour, Professor David Throsby, and social media platforms are becoming more important as venues for the discovery and on innovation in cultural organisations. A full research discussion of creative content. report will be published in Spring 2010. Unlike film and recorded music, live performance organisations produce ‘experiential goods’ whose features are less easy to translate digitally. Yet, digital technologies are impacting on live performance bodies such as theatres, live music, opera and dance companies too. The National Theatre’s NT Live broadcasts of live productions to digital cinemas may contain broader lessons for innovating organisations in the performing arts sector. With this in mind, NESTA has been conducting an in-depth research study on the two NT Live pilots that were broadcast last year – Phèdre on 25th June and All’s Well That Ends Well on 1st October.1 The research shows how this innovation has allowed the National to reach new audiences for theatre, not least by drawing on established relationships between cinemas and their patrons all over the country.
  • CHAPTER 4. Film Sound Presentation: Space and Institutional Context

    CHAPTER 4. Film Sound Presentation: Space and Institutional Context

    CHAPTER 4. Film Sound Presentation: Space and Institutional Context 4.1 Film Sound Presentation In the previous chapter I examined the preservation of early sound systems, namely the Biophon, Chronophone, Phono-Cinéma-Théâtre, and Vitaphone systems. In the analysis of preservation practices, I highlighted the importance of relevant elements of film sound: the material carriers, the technological devices and human actors, the dispositif situation, the film text, the screening performance, and the history of exhibition. These elements of preservation practices contribute to understanding and defining what film sound is and how it relates to film image. The analysis of the preservation of these early sound systems further demonstrated how preservation and presentation are two highly interconnected activities. As the shown by the example of the Tonbidler, the choice of a certain carrier in the preservation process is often incited by the context of presentation. As I will now argue in this chapter, decisions about the presentation of film sound similarly depend on decisions made during preservation. Preservation and presentation practices, intended as the core activities of film heritage institutions, point to a number of factors important in defining film sound and its core dimensions. The preservation practices examined in the cases of early sound systems highlighted in particular the three dimensions of film that I defined as carrier, dispositif, and text. The presentation practices that will be analyzed in this chapter will bring attention to other dimensions of film sound, namely the spatial and institutional dimensions, which are less evident in preservation practices. Film presentation concerns the screening situation, where the dispositif and the audience are central.

  • Iconoclasm in Visual Music

    Iconoclasm in Visual Music

    EMMANOUIL KANELLOS Iconoclasm in Visual Music Abstract From the earliest experimental film works to today’s contemporary and diverse use of moving image platforms, the notion of visual music is considered synonymous with abstract animation, because in part, abstract imagery is employed across the vast majority of musical visualisation. The purpose of this paper is to explore how the absence of figuration and representation in visual music can now reengage with the problematic debate of representation versus abstraction - a debate that has taken place in other art forms and movements in the past. Introduction Visual music is a type of audio-visual art, which employs the use of moving abstract images that are synchronised with music/sound. This approach to moving image works started prior to Modernism. However, it was during this period that it developed significantly and continues to expand the field in a variety of expressive ways in our current digital era. Although the subject area of this paper is visual music it will start with an outline of several known abstraction-representation dialectics in art and more specifically, the rejection of representation caused by different ideologies, political dogmas, and spiritual beliefs. In doing so, it will demonstrate the lack of representation in the creation of artworks throughout history and focus on the past and current situation in visual music. The abstraction-representation debate in visual arts is deep-rooted and has triggered some of the greatest conflicts in the history of art. Such examples include: two iconoclasms in Byzantine Empire in the eighth and ninth centuries; the label ‘Degenerate Art’ to describe Modern art during the Nazi regime; and the violent reactions in Syria, Jordan, Lebanon and Pakistan in 2006 over the cartoons that depict Muhammad.

    Real Time Music Visualization: a Study in the Visual Extension of Music

    REAL TIME MUSIC VISUALIZATION: A STUDY IN THE VISUAL EXTENSION OF MUSIC A Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Fine Arts in the Graduate School of The Ohio State University By Matthew Neil Bain, B.F.A. The Ohio State University 2008 Master’s Examination Committee: Approved by Professor Alan Price, Advisor Professor Maria Palazzi ____________________________________ Dr. Gregory Proctor Advisor Graduate program in the department of Industrial, Interior, and Visual Communication Design Copyright by Matthew Neil Bain 2008 ABSTRACT This work documents a design-led process of discovery for artistic development of real time 3D animations functioning as a visual extension to a live music performance. Musical dynamics, patterns, and themes are transposed into a visual form that develops over time through a carefully orchestrated process driven by the artist and the computer. Historical animations by Fischinger, Whitney, and “light organ” projections by Wilfred inform the work’s conceptual development. Various systems automate camera controls, audio analysis, and layers of motion in addition to providing the artist with a unique set of controls that demonstrate the effectiveness of the computer as a visual instrument for the artist. The complete system balances artistic responses, live multi-channel audio input, and computer control systems to orchestrate a real time visualization of a live music performance. The artist’s sensibilities and the computer’s generative capabilities combine to create a visually-focused member in the performing music ensemble. ii Dedicated to my Grandad iii ACKNOWLEDGMENTS I would like to thank my advisor, Alan Price, for his guidance, thought provoking conversations, and lunches.
