The experimental music of Chinese musicians including Yan Jun, Li Jianhong, Jun-Y Chao, Shen Piji and the Tea Rockers Quintet embodies a particular mode of thinking rooted in Chinese qi-philosophy known as shanshui (山水)-thought, which considers nature and the environment as secret and nurturing. Shanshui-thought cultivates an existential gesture of following rather than obeying or conquering; it requires tacit resonance rather than object knowing. Shanshui-thought enables us to recognise the cosmic, aesthetic and moral values of music qualities of dan (淡) (quiet and bland) and you (幽) (inward expandedness), once described as ‘poverty’ and ‘darkness’ by the composer Christian Wolff of what he calls ascetic minimalism.

In this article I outline the idea of an empirical/experiential reconnection to the natural non-human world through the practice of deep listening. I believe that the aesthetic experience is central to a more ecological positioning of the human being on earth and that aesthetic experience should involve a ‘rewilding of the ear’. To discuss this concept, I build an argument from Edgard Varèse’s music as ‘organised sound’ and approach it from a perceptual point of view. This leads to the discussion of other concepts, such as David Dunn’s ‘grief of incommunicability’ (Dunn 1997) and Jean-François Augoyard and Henry Torgue’s ‘sharawadgi effect’ (Bick 2008). Further to this I discuss parallels between Truax’s continuum (Speech–Music–Soundscape) and Peirce’s semiotic system. Taking points from these theories, we can discuss the possibility of the re-tuning of our ears to the wider sound palette of the world. I consider George Monbiot’s concepts of ‘rewilding’ and ‘rewilding of the human life’ (Monbiot 2014), in order to create a parallel to our relationship with the soundscape.

This paper introduces the concept of variable-coupled iterated map networks and explores its application to generation of musical textures. Such networks consist of one or more interlinked nodes. Each node consists of an iterated map function with a time-delay factor that schedules successive iterations. The value broadcast by a node can drive the variables and time-delay factor of any other nodes in the network, including itself. Lehmer's Linear Congruence Formula, an iterated map normally used for production of pseudo-random numbers, is explored for its own potential as a pattern generator and is used as the iterated map in the nodes in the examples presented. The capacity of these networks to produce richly gestural behaviours and mid-term modulation of behaviour is demonstrated.

Electroacoustic music, since its inception, has been situated in a cross-disciplinary no-man's-land, with areas of interest spread in many directions; from ideas of musical structures ordered through traditional pitch-classes to research on physical modelling and analysis of sound and compositional structures through the use of neural networks. Much of the material found in computer music has been developed through processes of appropriation, both from sound recordings of physical events and from the application of various principles found in the natural sciences.

This paper considers the early work of Alvin Lucier and its often problematic positioning between concert and installation work as a means of questioning how installation might be defined. Following an introductory survey of Lucier's work, a history of installation in the visual arts is traced through the debate, initiated by Michael Fried, on the ‘theatricality’ of minimalism. Fried's condemnation of the role of the viewer in what he termed ‘literalist’ art became, contrary to his intentions, a central element in thinking about installation work. Fried's position was recently engaged again by Hal Foster in positing a particular phenomenology of minimalist work, which is seen to be directly relevant to the example of Lucier. Having thus established the relevance of this phenomenology to the consideration of sound installations, whether they are themselves minimal works or not, discussion returns to the problematic example of Lucier, and the conclusion that the boundary between concert and installation works may always be permeable, that a precise morphology of installation will remain elusive.

This paper describes TAO, a system for sound synthesis by physical modelling based on a new technique called cellular sound synthesis (CSS). The system provides a general mechanism for constructing an infinite variety of virtual instruments, and does so by providing a virtual acoustic material, elastic in nature, whose physical characteristics can be fine-tuned to produce different timbres. A wide variety of sounds such as plucked, hit, bowed and scraped sounds can be produced, all having natural physical and spacial qualities. Some of the musical and philosophical issues considered to be most important during the design and development of the system are touched upon, and the main features of the system are explained with reference to practical examples. Advantages and disadvantages of the synthesis technique and the prototype system are discussed, together with suggestions for future improvements.

This article discusses how the notion of performance provides impetus for the design of interactive digital environments. These environments can ultimately be regarded as user-spaces; a condition which replaces the ‘fixed’ art-object with a configuration of interactions. Our understanding of space, as suggested by Lefevbre (2001), defines the ‘inhabitant’ as a full participant, a user, a performer of space. What is at play when the installation artist designs environments that invite performative exploration? The issue of improvised performance in the inhabiting of installation spaces is exposed. Two interactive installations by the author and works by others in the field provide a context for discussion and analysis.

Relations between histories, sources and preservation problematics are explored by evaluating how Dutch electroacoustic musical life is discussed in international histories of electronic music. Some Dutch cases consisting of different generations of interdisciplinary, live, performance-based electroacoustic work are discussed: the work of Dick Raaijmakers, Michel Waisvisz and Huba de Graaff. These cases point to some important aspects of preservation and the formation of histories. An emphasis in electronic music histories on technology and on technological innovation comes at the expense of information on the musical and artistic aspects. For greater interest in musical aspects, it is crucial to have more access to the music itself. The works and practices of Dick Raaijmakers, Michel Waisvisz and Huba de Graaff seem to resist documentation, ontologically and practically but, on the other hand, there is a desire for its documentation and dissemination. For their work, preservation means: making something new while being faithful to the past. It is therefore that I propose to regard preservation as performance. This music only remains alive when we are not solely interested in linear innovation, but in a profound relation with the past, in reworking the past.

This article discusses technical and aesthetic aspects of sound synthesis in the context of anacoustic modes of sound construction – a neologism that underscores the unique ontology of information in the digital domain. Anacoustic modes address the computer at its most fundamental level: the syntactic level of information. This changes the nature of signification as sound is considered first as an informational construct rather than a material circumstance, rupturing the front-loaded meaning that arises from our acoustic experience. Following certain concepts encompassed by N. Katherine Hayles’s posthumanism, anacoustic modes can be viewed as an expression of the materiality of information.

An electroacoustic musical work is a complex network of processes and elements: technical, musical, human, etc.; therefore, while the aesthetic perception is unified, its definition is fragmentary. This observation compels us to intensify our study of a taxonomy of agents and processes, with the aim of clarifying the identity of this music.

The discussion is positioned according to two different vantage points: (i) analysis of works, and (ii) the writings devoted to the aesthetics of electroacoustic music. Musicological analysis is simultaneously the means, the goal and the motivation for getting to know this arborescent reality. It allows us to arrive at the identification of six agents and four processes associated with the work, whose main properties we will describe. These elements are used as a methodological and theoretical grid for organising the discussion about the works. The question centres on a paradigm which is created from the analysis and returns to it, as an essential link between hermeneutic knowledge and the knowledge of the internal logic of an electroacoustic work.

Standard histories of electronic music tend to trace the lineage of musique concrète as lying mainly in the Futurists’ declarations of the 1910s, through Cage’s ‘emancipation’ of noise in the 1930s, to Schaeffer’s work and codifications of the late 1940s and early 1950s. This article challenges this narrative by drawing attention to the work of filmmakers in the 1930s that foreshadowed the sound experiments of Pierre Schaeffer and thus offers an alternative history of their background. The main focus of the article is on the innovations within documentary film and specifically the sonic explorations in early British documentary that prefigured musique concrète, an area ignored by electronic music studies. The theoretical and philosophical underpinnings of the documentary movement’s members, particularly their leader John Grierson, will be compared with those of Pierre Schaeffer, and the important influence of Russian avant-garde filmmaking on the British (and musique concrète) will be addressed. Case studies will focus on the groundbreaking soundtracks of two films made by the General Post Office Film Unit that feature both practical and theoretical correspondences to Schaeffer: 6.30 Collection (1934) and Coal Face (1935). Parallels between the nature and use of technologies and how this affected creative outputs will also be discussed, as will the relationship of the British documentary movement’s practice and ideas to post-Schaefferian ‘anecdotal music’ and the work of Luc Ferrari.

This article discusses the theoretical principles governing the short time Fourier transform (STFT) and its musical applications, using the CARL phase vocoder and the Composers' Desktop Project (CDP) spectral transformations. The former was originally developed by Dolson (1986, 1991) and ported to personal computer systems by Atkins, Bentley, Henderson, Orton and Wishart (Atkins, Bentley, Endrich, Fischman, Malham, Orton and Wishart 1987, Wishart 1994a). The latter was developed by Wishart (1994b). When possible, theoretical matters are presented in a qualitative way, keeping the number and complexity of mathematical expressions within the essential requirements for those interested in musical applications. The latter are accompanied by sound examples, including excerpts from pieces by the author.

Pierre Schaeffer's notion of Arts-Relais highlights aesthetic fissures in the passage from manual to mechanical techniques of sound production, fixation and reproduction. The Arts-Relais ‘instrument’ is a case of what Walter Benjamin terms technische Reproduzierbarkeit, and there is a close resemblance between the two roles of that instrument and the two manifestations of technische Reproduzierbarkeit as expounded by Benjamin. Furthermore, the Arts-Relaisinstrument materialises the shift from ‘older handwork technology’ to that technology which, in the words of Martin Heidegger, unlocks, transforms, stores up, distributes and switches about the energies of nature, and whose essence he terms Ge-stell. Heidegger's ‘sinking of the object into the objectlessness of the standing reserve’ (a feat of Ge-stell) intersects Benjamin's ‘decline of the aura’ (a feat of technische Reproduzierbarkeit), but while the decline of the aura paves the way for art as political praxis, the sinking of the object into the objectlessness of the standing reserve elicits from Heidegger an invitation to a return to the golden age of Greek techne. Is this not praxis too? And how does Schaeffer respond to Heidegger's invitation?

As befits an Homage to Schaeffer, this essay improvises ‘new uses for things originally meant for something else’ (Schaeffer and Hodgkinson 1987: 5), according to the rule of bricolage: to make do with whatever is at hand (Lévi-Strauss 1962: 17). A new structure is invested with disused remnants of old structures (Genette 1963: 37), as practised by the savage mind, structural thinking, musique concréte and Oswald de Andrade's antropofagia (Andrade 1928). One saves up by not making it to measure at the cost of a double operation: analysis (extraction of various elements from organised ensembles) and synthesis (organisation of these elements into a new ensemble where ultimately they will be entirely detached from their original functions).

This article explores the workings of genre in experimental electronic musics. Predominantly sociological in orientation, it has three main foci. First, it addresses practitioners’ and theorists’ resistances to the concept of genre in experimental musics. Drawing on recent developments in genre theory, it discusses the problems of agency, mediation and scale that any discussion of genre calls forth, pitting them alongside theories that emphasise genre’s necessity and inevitability in communication. The second section examines the politics of genre as they play out in practice, focusing on the Prix Ars Electronica festival and the controversy that ensued from the decision to change the name of the Computer Music category in 1999. The analysis focuses on issues of institutional mediation, historicity, genre emergence and the politics of labelling as they come into view when two broad spheres – electroacoustic art music and ‘popular’ electronic music – are brought into the same field together in competition. The third section deepens the analysis of Ars Electronica by zooming in on one of the represented genres, microsound, to examine how it is shaped and negotiated in practice. Using digital methods tools developed in the context of Actor-Network Theory, I present a view of the genre as fundamentally promiscuous, overlapping liberally with adjacent genres. Fusing Derrida’s principle of ‘participation over belonging’ with ANT’s insistence on the agency of ‘non-human actors’ in social assemblages, the map provides a means to analyse the genre through its mediations – through the varied industries, institutions and social networks that support and maintain it.

This article considers the place of William W. H. ‘Bill’ Gunn in the history of electroacoustic music with a focus on one of his earliest creative forays, the 1955 production of A Day in Algonquin Park, a composition in the genre of what the authors have dubbed the circadian audio portrait. In exploring Gunn’s compositional decisions and the political and creative contexts which surrounded them, we detail his sonic practice and make the argument that Gunn was a soundscape composer before the term was coined, a forerunner of the genre indebted to composers connected with the World Soundscape Project. In doing so, we must acknowledge the ways in which the album’s creation and reception play out paradoxical aspects of the wilderness myth, while feeding into the construction of a popular and idealised Canadian identity. We also find his modernist ecological sensibility struggling to articulate a place for human visitors within nature: in this, Gunn’s outlook and concerns were not very different from some contemporary soundscape composers. However, this study goes beyond acknowledging a previously ‘unknown father’ of familiar sounds and debates; in contextualising his work with environmental sound as a contribution to the genre of the circadian audio portrait, we highlight an alternative genealogy for contemporary soundscape composition.

This article proposes a perspective on certain practices within experimental music based on a particular understanding of sonic materialism. By tracing correlations and marking divergences between post-spectralism, minimalism, electroacoustic music, glitch and IDM’s offshoots, this article reflects on sound-in-itself, the conception of space and time in music, poietics, perceptual and cultural factors, and suggests that there is a particular understanding of sonic materialism – which I term ecstatic-materialism – that is rooted in a synthesis of perception, theory and embodied actions.

This perspective explores a new expressivity of sound in which the sound itself is the point of convergence for creative impulses and perceptual motives, sound being the common territory between composer and listener. By developing the idea of an ecstatic-sonic-materialism, various works across different genres can be brought together according to this mutual convergence on sound that embodies acoustic properties, intimate traces, external and corporeal experiences.

This article explores timescales within absolute and psychological times, and identifies the many factors that affect our perception of time passing and estimation of durations, which inevitably influence our perception of musical structures; in particular, it discusses listening experiences, and theoretical approaches to psychological states and emotional responses. It proposes a process according to which the time-influencing factors operate between listener and music. The discussion is approached through the lens of the electroacoustic composer and makes references to short excerpts from the author’s work and related repertoire. However, as the article discusses time in relation to sound structures, it is also relevant to other time-based sound art and music.

In his work Contropasso (1998–9) Michelangelo Lupone collaborates with Massimo Moricone in the dance showcase piegapiaga achieving direct interaction between dancers and live electronics performance. The choreography takes advantage of acoustic events as generated by three dancers and further elaborated on via computer by the composer through use of granular algorithms and digital filtering, allowing the construction of the musical events to occur in real time. The live electronics performer changes sound parameters in relation to the dancers' movements by use of the program SDP – Sonorous Drawing Plane (S. Lanzalone) – created specifically for the control of different synthesis algorithms allowing them to be processed on systems such as Fly30 (CRM) and Mars (IRIS). SDP reads and converts computer mouse data as the operator creates lines corresponding to performance gestures, thus creating both visible and audible output. This software allows a single gesture to control more than one parameter, thus creating complex changes in the audio programme output. The article deals with different compositions, performances and didactic situations the author has experienced using SDP.

In this paper I try to outline a model that can bring out the meaningful relationships between ‘the instrumental’ and ‘the electronics’ in mixed music. The model is based on the semiotic square which is considered in semiotics as a powerful conceptual framework to examine the relationships between two terms (S1/S2) and their negative (non-S1/non-S2), terms which can be characters, situations, actions, concepts, etc. Two paradigmatic axes represent the relations between the actors of mixed music: the sources (instrumental and electronic) on the one hand, and the manipulations (real-time processing and sound projection) on the other. According to the semiotic square, the relations inside the environment are defined in terms of contrariety, contradiction and complementarity. This model allows us to start out with a purely technological description of the ‘mixed music’ genre and of individual pieces, with the advantage of a pre-operative analysis of the system. It describes the immanent structure of the environments and releases the potential interactions between the instrumental and the electronics of mixed music. These interactions are examined, from a paradigmatic point of view, with numerous representative pieces of mixed music from the twentieth century.
