With similarities to the emergence in fifteenth-century landscape paintings, to poems by the Transcendentalists and to the more recent 1960s land art movement, environmental sonic art is always context-based and conjointly performs as environmental activism with aims to break down the nature/culture dualism. Nature, however, is both a material object and a socially constructed metaphor that is infinitely interpretable and ideologically malleable based on one’s values and biases. Does the environmental sonic artist acknowledge this? The theoretical framework of this article extends acoustic ecology, first theorised by R. Murray Schafer, to include environmental history and cultural theory – ultimately problematising definitions of ‘nature’ and ‘natural.’ Through this framework, the author critiques the way composer John Luther Adams represents his environmental sonic art. This analysis will illuminate a dialogue that asks, ‘What is self-critical environmental sonic art?’

This paper documents elements of a research project undertaken between 2008 and 2012. Building upon the Intention/Reception project of Leigh Landy (2006) and Rob Weale (2005), the project sought to investigate audience interpretations for works of electroacoustic audiovisual music and to utilise an expanded understanding of the audience – as active participants in interpretation – to subsequently inform the composition of new works. This project combined three distinct research methodologies: empirical data collection, scholarly research and composition. The composed works were both informed by the results of empirical data collection and scholarly research, and adapted (re-composed) throughout the latter stages of the research in order to explore emergent research findings and research hypotheses.

Interpretations were demonstrated to be contingent upon the individual lived experience of an audience member, with aspects of the work's discourse acting to narrow the interpretative potential of the work. The use of mimetic materials (sonic or visual) within works of electroacoustic audiovisual music were demonstrated to be potentially obstructing to an aesthetic interpretation of the work. And the importance of recognising the distinction between physical signal and perceived object was highlighted within the process of composition and the subsequent testing.

It is a habit to invoke Aristotle when dealing, within the arts, with ‘Nature’ – that the Man–Artist (and not only the musician) would be, he says, ‘inclined’ to imitate. It is true, the history of music clearly attests to the temptation and of the ‘pleasure’ (as Aristotle also says) found in mimesis. We know that very lately in history musique concrète gives a new perspective to this question as well as to other questions, and changes the deal: because the sound objects of the world, of the whole world – the ‘noises’ – that needed to be imitated, can now be easily captured through technology, almost in a photographic way, and then they can be gathered, kept, and finally be composed. Hopefully Pierre Schaeffer, its genial inventor, has, concerning the question of nature within new music, a position that tears him apart, which is paradoxical, uncomfortable, fundamental: that the nature that is so easily captured, he does not want to exhibit; to understand the lessons, the hidden musical lessons, he only wants to examine it. This almost heroic model will only be partially followed by the composers (concrète, electroacoustic, acousmatic, anecdotical composers) who have been working during the last sixty years in this passionate domain. At the end of this article, the sketch of a typology, based on musical examples, tries to clarify the way nature is dealt with, when it appears in musique concrète.

Drawing on Deleuze’s work about cinema (the ‘movement-image’ and the ‘time-image’), this article explores formal and aesthetic resonances with sound-based music, distinguishing between aesthetics of energy, articulation and montage, and aesthetics of contemplation, space and virtual relations. A second perspective is given, focusing on how listening behaviours may impose a ‘movement-image’ or a ‘time-image’ lens through which we could experience and remember a work’s form. This is exemplified with a short analysis of the first section of Chat Noir (1998–2000) by Elizabeth Anderson.

This article is an attempt to demonstrate the relation between appreciation of morphology and structure in form on the one hand, with higher symbolic structures – crucial for meaning formation routines – on the other, and to evaluate their significance in transmedial narratives, primarily in the case of media-based artworks. The use of catastrophe theoretical models to classify forms, their structure and dynamics is proposed, and the question of how these models can give us insight into the meaning that is carried through transmedial narratives (referential or abstract) is examined. Finally, the value of these insights for the composition and practice-based analysis of multimedia art forms is demonstrated.

Reflecting upon Max Neuhaus’s and Alvin Lucier’s first electronic works on electroacoustic feedback, I will consider how their research into live electronic music, meant to be performed on stage, announced a whole other form of creation, which was paradoxically emancipated from the concert hall and essential to the emergence of sound art: sound installations. If both musicians first appropriated the electronic medium for its possibilities in sound transformation, it appears that these experimentations, and more precisely those using feedback, quickly extended into areas other than research on tone and the live dimension of electronic performances. Indeed, electroacoustic feedback, as a phenomenon of retroaction, goes beyond the mere relationship to the instrument: by manifesting itself in the looping of the electroacoustic chain (microphone-amplification-speakers), it straightaway inscribes the electronic device in a spatial dimension that is linked to the propagation of sound. By analysing Neuhaus’s and Lucier’s first experiments with feedback, the specificities of their apparatuses and the experiences they aimed to create and foster, this article wishes to question the role these experiments played in the emergence of both musicians’ concern with space, which is at the core of any understanding of their later works. We can then re-read their contribution to the history of live electronic music in the light of both bifurcations and lines of flight inherent in their respective bodies of work, in order to look into the emergence of a certain art of sound installation, in which the liveness of live electronic music, far from being pushed aside, seems to lead into other forms of creation and specific aesthetic questions.

This article discusses the responsive sound installation Reeds. The Reeds project was commissioned by the Melbourne International Festival of the Arts in 2000, and first exhibited in November and December of that year on the Ornamental Lake at the Royal Botanic Gardens, Melbourne. It consists of twenty-one large floating sculptures, modelled to represent clusters of river reeds in immaculate man-made plantings. Each reed pod contains a collection of electronics for either the gathering of weather information or the reception and dispersion of sound. The sound installation gathered data from two real-time weather stations, and produced eight channels of musical output by interpreting the machine unit pulses of the weather data as pulse inputs to Inverse Fast Fourier Transform (IFFT) algorithms. The Reeds project focused on a consideration of multiple streams of chaotic and constantly varying sound. I was interested in exploring whether the sonic environment would remain homogenous even though, unlike a musical ensemble, the control inputs varied randomly and independently of each other. The sound installation was site specific, reflecting directly upon the environment it inhabited, both in terms of its visual quality, and aesthetic of the sound.

Atmospherics/Weather Works is an interdisciplinary project in the sonification of storms and other meteorological events generated directly from atmospheric data produced by a highly detailed and physically accurate simulation of weather systems. This paper discusses the background, conception and execution of the first stage of the project that has resulted in several performances, stereo recordings, a multi-channel spatialised sound installation, and an interactive sound environment.

Various algorithmic techniques are available for generating music, many of which come from the field of artificial intelligence, which is rich with potential in this regard. However, the musical appropriateness of these techniques is less clearly understood. In this paper, I will report on a study that aimed to describe the characteristics of two of these techniques, rule-based and genetic algorithms, as they apply to melody generation. The appropriateness of these characteristics in contributing to well-formed melodies was judged by aesthetic criteria. The results indicate that most combinations of rules, mutations and evolutionary selection result in poor or average melodies, but that careful combination of these techniques can generate melodies that are not simply well-formed but in many cases display some elegance and novelty.

This article explores the spatial identities of the flautists in playing Kaija Saariaho's music with live electronics, particularly reverberation and harmonisation. The varying spatial position of the flautists are theorised mainly via two approaches: that of ‘local/field’ concepts by Simon Emmerson, and through the philosophy of narrative identity developed by Paul Ricoeur. The article investigates the flautists' experiences of control over the sound, and especially its most intimate form, direct control, by discussing the relationship between the choices of live flautist and the sound director. The sound result is constantly negotiated by several authorial activities, the contributions of which are closely overlapping and conversing with each other.

This article describes the theories and practices of the German installation artists and composers Sabine Schäfer and Joachim Krebs. Much of their work concerns site-specific sound installations involving the articulation of time and space. Their principal work methods and materials are described. In addition, they have formulated a typology of five installation types which they describe using their own installations as examples. Each installation type responds to a particular set of aesthetic and practical challenges both for the artists and the visitors. These are discussed and illustrated in the article. The typology extends beyond the specific work of these artists and can be applied to installations in general, thus providing a framework for critical analysis. Furthermore, the translators have discussed the issues regarding the specialised vocabulary of the artists and the rendering of such language into English.

Stockhausen’s graphically notated Pole für 2 was created for the multi-channel diffusion system in the spherical auditorium at the German pavilion at the Osaka World’s Fair in 1970. The work is remarkable for the way in which spatiality is explored through new developments in graphic notation – both for three-dimensional and sound projection, and to indicate musical imitation and transformation of short-wave radio signals. These two notational systems unite through the synchronous unfolding of time in Pole, and similarly through the spatial structure of auditorium’s architecture that housed over 50 loudspeakers in 6 layers. By using the sound projection score as the basis for the construction of a NURBS (non-uniform rational B-spline) model, each of the player’s sound projection geometries within the auditorium can be transmediated, thus allowing for a visual representation of the spatial design of the work. Examining the topology of the models produced from the work’s six sections further allows for emergent architectonic characteristics of volume, manifold and envelope to be tracked, thus pointing to Stockhausen’s characterisation of design space. The strong connection of the work to the auditorium’s spherical structure also points to the nature of the composer’s sound design as one predicated on the ability of patterns of sound projection to articulate tangible space, and therefore produce ephemeral aural architectures.

This paper describes an exploration of utilising the World Wide Web for interactive music. The origin of this investigation was the intermedia work Telemusic #1, by Randall Packer, which combined live performers with live public participation via the Web. During the event, visitors to the site navigated through a virtual interface, and while manipulating elements, projected their actions in the form of triggered sounds into the physical space. Simultaneously, the live audio performance was streamed back out to the Internet participants. Thus, anyone could take part in the collective realisation of the work and hear the musical results in real time. The underlying technology is, to our knowledge, the first standards-based implementation linking the Web with Cycling '74 MAX. Using only ECMAScript/JavaScript, Java, and the OTUDP external from UC Berkeley CNMAT, virtually any conceivable interaction with a Web page can send data to a MAX patch for processing. The code can also be readily adapted to work with Pd, jMAX and other network-enabled applications.

How is performing with responsive technology in a mixed work experienced by performers, and how may the notion of embodied cognition further our understanding of this interaction? These questions are addressed here analysing accounts from singers performing the author’s mixed work Metamorphoses (2015). Combining semi-structured interviews and inspiration from Interpretative Phenomenological Analysis, questions concerning the ‘self’ when listening, singing, moving and relating to fellow musicians, as well as the relationship towards the computer, are explored. The results include a notion of the computer as neither separated nor detached but both, and highlight the importance of the situation, including not only the here and now but also social and cultural dimensions. The discussion emphasises the role of sensorimotor interaction and bodily experience in human meaning-making.

The telematic work instance is a performance for viola and dance that digitally connects performers in Vancouver and Cape Town. The network interface enables a violist and a dancer to simultaneously play multi-user digital music-dance instruments over the internet with music and dance. The composition, design and performance interaction of instance draw from acoustic multi-user instrument paradigms and music-dance interactions in the African performing arts to explore the idiosyncrasies of the telematic performance space. The iterative design process implements soma-based research methods to inspire sonic compositional material with the body and to explore the performers’ embodied experience of sonic aesthetics during their interaction.

In contrast to general perceptions of noise as undesirable audio phenomena, consideration of the objective acoustic properties of ‘noise’ and the functional aspects of noise in Information Theory are used to show how, rather than an impediment to communication, noise can aid in increasing communication. A review of noise in music of the twentieth century and beyond shows how this has become increasingly understood by composers, and that the greater use of noise as a sound source has arisen out of developments in audio technology. This article argues that the music of Carsten Nicolai (alva noto) represents a consolidation of this process. The Autorec CD and the track Impulse are cited as examples of how noise is used as part of a new practice in electronic music. By looking at the structural features of the cited musical examples, it is seen how this new practice follows neither the electroacoustic nor the commercial dance music mainstreams but manages to synthesise references to both traditions.

the memory machine is a context-, people- and site-specific interactive sound installation. it has been developed as a collaboration between two composers, cathy lane and nye parry, who share an interest in sound, oral history, and memory. the memory machine is an ongoing project which, most recently, was part of the british museum's 250th anniversary exhibition entitled the museum of the mind; art and memory in world cultures.

this paper discusses the background and ideas behind the memory machine within the context of the composers' work. the development of the project in collaboration with the british museum is described and an evaluation of some of the issues around the public exhibition of the piece is given as well as a full technical description of the different elements of the installation.

Perceptual dimensions underlying timbre and sound-source identification have received considerable scientific attention. While these scholarly insights help us in understanding the nature of sound within a multidimensional timbral space, they carry little meaning for the majority of musicians. To help address this, we conducted two experiments to establish listeners’ perceptual thresholds (PT) for changes in sound using a staircase-procedure. Unlike most timbre perception research, these changes were sonic manipulations that are common in synthesisers, audio processors and instruments familiar to musicians and producers, and occurred within continuous sounds (rather than between discrete pairs of sounds). In experiment 1, two sounds (variants of a sawtooth oscillation) both with the same fundamental frequency (F1: 80 Hz, 240 Hz or 600 Hz) were played with no intervening gap. In each trial, the two sounds’ partials differed in amplitudes or frequencies to produce a timbre change. The sonic manipulations were varied in size to detect thresholds for the perceived timbre change – listeners were instructed to indicate whether or not they perceived a change within the sound. In experiment 2, we modified stimulus presentation to introduce the factor of transition time (TT). Rather than occurring instantaneously (as in experiment 1), the timbre manipulations were introduced gradually over the course of a 100 ms or a 1000 ms TT. Results revealed that PTs were significantly affected by the manipulations in experiment 1, and additionally by TT in experiment 2. Importantly, the data revealed an interaction between the F1 and the timbre manipulations, such that there were differential effects of timbre changes on the perceptual system depending on pitch height. Musicians (n=11) showed significantly smaller PTs compared to non-musicians (n=10). However, PTs for musicians and non-musicians were highly correlated (r=.83) across different sonic manipulations, indicating similar perceptual patterns in both. We hope that by establishing PTs for commonly used timbre manipulations, we can provide musicians with a general perceptual unit, for each manipulation, that can guide music composition and assessment.

Technology influences all art, and therefore all music, including composition, performance and listening. It always has, and it always will. For example, technical developments in materials, mechanics and manufacturing were important factors that permitted the piano to supersede the harpsichord as the primary concert Western keyboard instrument by about 1800. And with each new technical development new performance issues have been introduced. Piano performance technique is quite different from harpsichord technique, and composers responded to these differences with new music ideas and gestures. The multiple relationships between technology and composer and performer are dynamic and of paramount importance to each party. And a true consideration of any aspect of music requires that all three areas be examined. This has always been a part of music, and so these relationships are inherently important within computer music. The difference is that electronic technology has caused a fundamental change for all aspects of music, a difference that is as pivotal in the history of Western music as was the shift from oral to written preservation of music over a thousand years ago, and then also the accessibility provided by printed music five hundred years ago. In computer music, all parties are always acutely aware of the presence and influence of machine technology in both the visual and audible realms.
