This article is the final stage of seven years of research dedicated to understanding the theoretical backgrounds of Brazilian electroacoustic music in which a significant amount of data was gathered from a series of questionnaires and interviews with Brazilian composers. Our research focuses mainly on the influence of what we have called the historical matrices: musique concrète, elektronische musik and computer music. We were able to determine to some extent how much each of these matrices weigh on the poetic and poiesis of the Brazilian electroacoustic production. We were also able to shed some light on how (and if) Brazilian composers relate to these matrices aesthetically and if their relation to them is merely technical, as well as trying to understand how clear cut the borders are between these two aspects of musical creation. The concepts of oppositional culture (Ogbu 1978) and established and outsiders (Elias and Scotson 2000) also helped us understand the dynamics between academia and a certain anti-academic stance seen in some composers of the genre. Using these same concepts, we elaborate, in a final note, on some brief comments about a newer generation of composers who, due to various aspects, were filtered out during the early methodological stages.

Sound and media installations are rarely considered from a time-based, formal perspective. In order to enable a greater understanding of temporal form in sound installations, I suggest a cross-disciplinary adaptation of musical form to the installation context. Due to the differences between concert and installation presentation practices – including, but not limited to, the increased agency of the mobile visitor – I re-examine form in installation contexts as the particular temporal experience co-produced by the first-person subject as they navigate in, through and out of the work’s frame. By applying this musical perspective to macro-scale formal structures, a set of tools and concepts become available for the analysis of temporal form in existing sound or audiovisual installations. Using practice-based observation and analysis, I describe several compositional strategies through which musical concepts of material and form can be extended in space and time: each of these strategies provides means with which to shape or constrain the visitor’s co-production of experiential form. Finally, I discuss several strategies that can be used for the creation of large-scale form, with particular reference to algorithmic design principles used in my recent audiovisual installation, Room Dynamics.

This article examines creative sound practitioners who audibly convey social justice commentary through their use of environmental soundscapes as source material. I discuss how micro-watt radio pioneer Mbanna Kantako, electronic music artist Muqata’a and audio activist Christopher DeLaurenti work with field recordings to produce subversive counter-narratives against news media and state discourses. I outline three specific sound projects as case studies: Kantako’s aural counter-surveillance of police encounters within the predominantly poor and Black neighbourhood of Springfield, Illinois; Muqata’a’s album Inkanakuntu (2018) composed using field recordings of Ramallah, West Bank; and DeLaurenti’s radio piece Fit the Description (2015) that incorporates field recordings of the protests following the 2014 police killing of Michael Brown in Ferguson, Missouri. I argue that composing with soundscapes of contested urban spaces can function as sonic activism that confronts the oppressive soundscapes of systemic racism. The case studies are examined through the following common themes: 1) the use of what I term aural counterpublics to amplify marginalised voices and soundscapes of resistance, and 2) the radical re-appropriation of microphones and oppressive police and military audio technologies as a means of ‘speaking back’ to systems of power. Finally, I suggest how these case studies convey the need for intersectional and decolonised approaches to soundscape studies.

The history of sonic arts is charged with transgressive practices that seek to expose the social, aural and cultural thresholds across various listening experiences, posing new questions in terms of the dialogue between listener and place. Recent work in sonic art exposes the need for an experiential understanding of listening that foregrounds the use of new personal technologies, environmental philosophy and the subject–object relationship. This paper aims to create a vocabulary that better contextualises recent installations and performances produced within the context of everyday life, by researchers and artists at the Sonic Arts Research Centre at Queen's University Belfast.

The applications of technology in instrument design contribute to the resulting sound on many levels, particularly in the context of new evolutions representing the traditional instruments of our culture. Materials technology is seldom given consideration in the description of Western string instruments, but our choices of woods, metals and synthetics can dramatically alter the sound without altering the substance of instrumental performance. In the design of modified string instruments which mimic features of natural acoustic predecessors, new technology is applied on many levels. A taxonomy is proposed for the past, present and future of instrument design. Due consideration is given to the music which results from the new sound world, especially that involving interactive electronic processing. The advantages and disadvantages of directions in instrument design for the future are evaluated within the proposed schema. Some extended techniques on the cello are proposed to be further extended with electronics, and audio examples and descriptions are provided. A model for future collaborations between composer, performer and engineer is proposed.

Modalys-ER is a graphical environment for creating physical model instruments and generating musical sounds with them. While Modalys-ER provides users with a relatively simple-to-use interface, it has only limited methods for mapping control data onto model parameters for performance. While these are sufficient for many interesting applications, they do not bridge the gap from high-level specifications such as MIDI files or Standard Western Notation (SWN) down to low-level parameters within the physical model. With this issue in mind, a part of Modalys-ER has now been ported to OpenMusic, providing a platform for developing more sophisticated automation and control systems that can be specified through OpenMusic's visual programming interface. An overview of the MfOM library is presented and illustrated with several musical examples using some early mapping designs. Also, some of the issues relating to building and controlling virtual instruments are discussed and future directions for research in this area are suggested. The first release is now available via the IRCAM Software Forum.

The label Mille Plateaux focuses on concepts like virtuality, noise, machinism and digitality. In the most simple case, digital music simulates something that does not exist as a reality; it generates something new. It is the result of the teamwork of numerous authorities such as the 'musician', the programmer and the authority of the software program. Today, computer digital music can be seen as screen-based music, i.e. sounds become visible and images audible, but one can often forget that there is no mutual correspondence; and that this is simply a mechanism whereby a given program secretly directs the programmer towards significant ways of performing, creating apparently absolute relationships between image and sound. On the other hand, with the increasing complexity of software, the programmer loses insight into internal communication structures. Such complex programs are full of errors and can even act on their own initiative. Programmers and musicians who navigate through today's systems function as designers. But this is less a question of the design of a program's operation surfaces but of the programming of software and the navigation by its logic. One has to discuss the medial conditions of digital music, the more user-friendly the software, the less transparent is the medium itself; i.e. the more transparent the functions of a computer or a synthesizer (say, with the use of preset sounds), the stronger the medium proves to be non-transparent. Digital music is more about opening up given program structures; internal ramifications and program hierarchies are to be discovered.

Most accounts of rhythm focus on notions of duration, pulse and metre, to explore the practices and constructs by which those involved in music performances co-ordinate their involvement. Yet there is a significant body of musical practice where sounds co-habit in time, without the same sorts of constraints found in metric co-ordination: from the gentle singing of Joseph Beuys during his Action Piece I Like America and America Likes Me, to Paul McCartney's song ‘Blackbird’. This is similar, say, to the improvisation practice of composer and trombonist George Lewis in his work with the computer programme Voyager. Starting from some ideas laid out by Gaston Bachelard and Gregory Bateson, and recent writings on critical post-humanism, this paper explores ways of considering ecologies of sounds in time, and their consequences for human musical experience.

Given the growing acceptance of information and communication technology (ICT) as integral to today's middle and secondary school classrooms, electroacoustic music would seem on the surface to be a central feature of the music curriculum. However, models that approximate actual practices of electroacoustic music in the classroom are rare, with many schools focusing squarely on ICT, either as tools to facilitate traditional musical contexts or to explore innovative uses of that technology. Also, with the exception of some notable recent developments, there are few initiatives to bring middle and secondary students, or their teachers, into contact with the practices of electroacoustic music communities. The purpose of this article is to explore this problematic gap between the education and electroacoustic music communities in an attempt to identify some of the issues that lie at the foundation of an effective curriculum. The position taken is that these foundational matters need to be addressed prior to any discussion of ‘best practices’ for middle and secondary electroacoustic music education.

The applications of digital technologies in the world of art continue to explode, and various artistic disciplines begin to converge as a result. More artists are working in a wide variety of media while, at the same time, increasing specialisation results in a greater number of collaborative, interdisciplinary activities. The ability to collaborate effectively with other artists is a skill set that must be addressed from a curricular standpoint, and music faculty must engage with colleagues in the other arts to provide students with the appropriate learning opportunities. While many institutions have developed successful models for doing this, information about those models has not been widely disseminated. Institutions that have found this change difficult may face a variety of obstacles, including highly compartmentalised departments, a crowded curriculum, and shortages in staffing and funds. One model for change is presented that focuses on building curriculum and shared facilities, using technology as a means to facilitate interdisciplinary collaboration.

The article is a discussion of works by two Danish composers who both, with self-constructed instruments, challenge computer music as genre, the understanding and use of conventional technology, and the music's relation to history. At first glance, the use of homemade instruments appears to be a common characteristic. But, when one takes a closer look, different discourses and various discussions of media and materiality are revealed. In the article the various positions are unfolded through discussions within the theoretical field of media archaeology – a science with its roots in media studies, but also an important framework for the production and understanding of a variety of DIY practices.

The overall purpose with the article is twofold: on the one hand it illustrates how theories from the field of media archaeology contribute interesting perspectives to discussions of artistic work within the area of DIY. On the other hand, it also serves as a critical discussion of media archaeology as not necessarily the solution to every aspect of artistic practices. The two artists are Morten Riis and Goodiepal.

This article argues that pop music’s increasing assimilation of hip-hop and EDM (electronic dance music) practices combine with computational automation and this has substantial consequences for musical space. Traditional ‘space-makers’ such as reverb or delay are subject to other functions such as frequency filters and compression that interrelate processual layers of textures. Instead of an active-listener-orientated sonic space with distinct source-bonded entities, it is based on a particular sonic materiality. With a new media theoretical approach, I consequently argue that this new type of space can better be understood as a mediatised topological materiality.

The highly rewarding experience of electronic music persists throughout our daily lives. Our immediate environments are replete with events that emit sounds that are extremely complex. Electronic music engages with the listening habits we take for granted in our everyday lives, and reveals how intricate they can be. Inspired by such intricacies, I have conducted a series of listening experiments with 80 participants over the course of three years to explore the cognition of electronic music. In this article, I will first present the method and the results of this experiment, including a categorical analysis of mental associations evoked by different works of electronic music. Next, I will offer a discussion of narrativity in electronic music supported by these results and diverse perspectives on narrativity from a number of disciplines. I will then construct a definition of gestures as narrative units in electronic music in relation to events in the environment. In doing so, I will bring together various theories on electronic music with not only the findings of the current study but also existing research on auditory cognition.

Group multi-disciplinary projects face difficult challenges in social collaboration, diverse technologies and aesthetic grounds. Combining sound, image and space into a sufficiently malleable set of materials for creation is a complex task. As such projects lack a common ground from which to start, an experimental, practical approach is suggested, with a non-hierarchical, informal group structure. The Meta-Orchestra project, tackling these problems since 2000, re-engaged with the issues in a fourth meeting in Maastricht in 2004. This paper lays out the context of multi-disciplinary work, influenced by developments in computer technologies, by outlining the changed roles of the orchestra, the score and audio-visual theories. The Meta-Orchestra is described against a theoretical frame of social, technical and aesthetic considerations. Although the project will not be forced into this framework, descriptions of the palette, the strategies to create common grounds, the areas opened up by wireless network technologies, aesthetic issues of layering sounds and images, and the development of a central score system, illustrate the layered complexities of the Meta-Orchestra.

Project Arbol:Deer-B-Gone is a an outdoor sound installation of indefinite duration for twenty-three speakers. It takes on a guerrilla approach to sound installation art. Low-tech concepts and supplies, such as car amplifiers, aircraft cable, inexpensive cassette players, coupled with an overall irreverence for mainstream consumerism, created something like a Disney World theme park gone awry. The installation, which was site-specific, took place in a backyard in Princeton, New Jersey, USA. Yards and yards of cable were woven through the trees. Speakers were later mounted on the cable. Once in place, the speakers moved slowly along the cable. Each speaker played its own sound track. While there were some technical difficulties that plagued the project throughout its development and performance, overall Project Arbol proved to be a resilient installation.

This article attempts to identify trends in non-academic Japanese electronic music related to the representation of identity issues including gender, sexuality, ethnicity and race. Simultaneously, it attempts to point out limitations in Western identity politics which complicate the identification and clarification of such themes. In particular, the Western desire to define cultural diversity through a multiplication of distinct identity constructs is contrasted with Japanese aversions to images of factionalism or political affiliation. It is postulated that the ‘Globular’ identity politics found in Japanese electronic music suggest ways of thinking around Western ideological conundrums such as the tendency to use terms of ‘equality’ (a notion of similarity) when negotiating for communal ‘diversity’ (a notion of dissimilarity). This extends to current attempts at diversification among academic and commercial digital audio producers.
