This article proposes four paradigms of group performance in free improvisation: 1) sound composition; 2) social communication; 3) ‘parallel play’; and 4) ‘one beast with many heads’. While these paradigms are identifiably different, they are often engaged flexibly and/or in combination; and, importantly, it is very possible for the same performance to be experienced or interpreted by different performers or listeners according to different paradigm perspectives. After providing some background and defining key terms, the four paradigms are introduced and discussed; connections with, and departures from, the existing literature are considered, followed by analysis of illustrative examples of each of the four paradigms drawn from the broader field of sonic and electroacoustic improvisation. To conclude, further larger-scale research potential for furthering this investigation is identified.

This article introduces a framework for musical analysis applied to electroacoustic improvisation. After an introduction about the benefits of interdisciplinary research and research-creation practice there is a description of the different domains of the framework: acoustic analysis, music analysis itself and the design of graphic representations. The framework is based on the extraction of information from the audio signal (music information retrieval) to create data representations, some of which are very efficient for music analysis, such as the brightness standard deviation or the self-similarity matrix. The last part of the article demonstrates the use of the framework on extracts of electroacoustic improvisations performed by the Paris-based group Les Phonogénistes, of which the author is a member.

Two improvisation scenes emerged in the late 1990s – Echtzeitmusik in Berlin, and in London the New London Silence – with similarities in aesthetic and approach. Among these is a tendency towards a more silent and less responsive style of improvising often referred to as reductionism, and the inclusion of electronic resources, with a complex interaction between the two. This article introduces these two scenes and their respective approaches, and uses interviews with key improvisors in each to interrogate the performers’ approaches to electronics, and whether this plays a role in determining and developing their aesthetic and performance style.

This article builds on Richards’s work to formulate an understanding of the emerging practice of performance-installation, which embraces sound art, DIY electronic music and maker culture. A number of key points are addressed in this formulation: making/unmaking and ‘public making’; the assembling/disassembling of sonic devices and artefacts in the performance space; sound ‘through’ materials and materials at hand; and site and architectural features as material. In addition, readymade actions, illustrated by George Brecht’s The Cabinet, and the relationship between audience and performer are also presented. The article continues by outlining practice undertaken by the authors comprising two UK tours: ‘Sacrificial Floors’, 2018 with Tetsuya Umeda; and ‘Points of Failure’, 2020. Derek Bailey’s idea of ‘instrumental impulse’ is extended to include the concepts of expanded and reduced instruments that encompass ‘instrument as object’ and ‘raw material as instrument’. ‘Instrument’ is also viewed as a distributed mesh-like structure in which collective improvisation may occur. Borrowing from Ingold, ‘wayfaring’ is used to describe improvising with materials found ‘along the way’. Silent actions, uncontrollable instruments, unstable systems, performative failures, reimagined affordance of objects, ‘playing with resource’ and ‘improvising inside electronics’ are all addressed in relation to performance-installation. Finally, the authors explore the idea of ‘virtuosity in listening’, and question sonic autonomy and self-expression in improvisation and how ‘attending to sound’ can be an active part of improvised performance.

This article will examine the music of two improvisation scenes – Seoul’s ‘Dotolim’ and Tokyo’s onkyô – with a particular focus on their use of gesture and texture. The article centres on an analysis of a trio performance by Jin Sangtae, Hong Chulki and Tetuzi Akiyama, which effectively brings these two musical communities together in a collaborative performance. This analysis demonstrates that focusing on gesture and texture can help in perceiving essential aspects of an improvised performance, including understanding strategic modes of listening and interplay, musical structural developments (both micro and macro) as well as identifying applied roles of instrumental technique and approach.

The composer Pauline Oliveros emphasised that her music was a by-product of a larger humanistic project aimed at raising awareness and sensitivity through social interaction and community-building. In this article, I highlight the role of technology in facilitating social interaction in improvisatory contexts by considering three examples that span Oliveros’s career: the composition In Memoriam: Nikola Tesla, Cosmic Engineer; her telematic performances; and the Adaptive Use Musical Instrument (AUMI) project. In each of these examples, technological mediation transforms musical and social interaction in unpredictable ways, presenting obstacles that require participants to work cooperatively to resolve them. This intensification of Oliveros’s larger project is considered through several complementary theoretical frameworks, including Don Ihde’s theory of technological mediation, Daniel Belgrad’s concept of deutero-learning in improvisation and Georgina Born’s orders of social mediation in music. By deploying technology in visible – rather than invisible – ways, and by inviting participants to adapt to and even embrace unexpected elements that might otherwise be regarded as limitations, Oliveros’s work reveals how technology can simultaneously be understood as an affordance for music-making and an extension of a deeply social and community-oriented endeavour.

In a previous edition of Organised Sound, I discussed the potential for using the North Indian sarode in electroacoustic music. In that article, I explored how electroacoustic music artists manage to integrate multiple cultural frameworks, while also acknowledging the importance of personal artistic agency. The primary question that emerged from that research is extended in this article: how does an electroacoustic performer of a non-Western instrument improvise outside the idiom of their tradition? In order to address this question, I draw on Tomlinson’s concept of the metaphysical imaginary. In my own performance practice, I employ the metaphysical imaginary as a framework to explore a transcultural, transcendent, perhaps even spiritual potential of electroacoustic improvisation. The metaphysical imaginary will be explored in two dimensions: the synchronic and the diachronic. The synchronic dimension looks horizontally across cultures, while the diachronic dimension looks in a temporal verticality, looking inwards and downwards, to a time before modern culture. In the article, I discuss the performance practice of other musicians working across different cultural frames who explore the metaphysical in their improvisations. The article also looks backwards in cultural historical time and investigates how improvisers draw inspiration from a pre-modern cultural world, combining these imaginaries with modern sound techniques. I will situate my own work within this mosaic of practices, concluding with a discussion of electroacoustic improvisations using the sarode, extended technique and the re-imagining of pre-historic sonic rituals.

The desire to work in real time and improvise with the possibilities of tape-based studio practice was a key design intention of early modular synthesisers. The resulting instruments, in particular the Buchla, emphasised possibilities for the creation of musical structure in combination with components designed to enable real-time, expressive interaction. As smaller, keyboard-based synthesiser instruments achieved broad commercial success, many of the possibilities for the real-time creation and manipulation of musical structures, developed in the larger modular synthesiser designs, were not carried forward into the new age of commercial electronic music instruments. The resurgence of the modular synthesiser has seen these possibilities for improvisation of musical structures revisited, opening up processes and approaches that were almost lost to a new generation. Following an analysis of the genesis of modular synthesisers, with a focus on the Buchla, this article describes three examples of modular synthesiser-based compositional processes that enable the performer to undertake improvised actions in real time that construct, influence and distort musical structure. These examples are then analysed to better understand the processes, motivations and experiences of using a modular synthesiser to construct musical structure in a real-time and improvised fashion.

This article discusses the compositional taxonomy of music theatre works by Constança Capdeville (1937–92) and offers a way to analyse her music and collaborative processes and also the performance of her work through a case study of the piece Double. Capdeville’s works include different elements such as music, settings (staging), movement, text, tape-recorded sound, visual image, props, costumes and lighting. Documentation for the compositions is scattered across different sources or simply lost, making it difficult to reconstruct the works as they have improvised hypothetical components and idiosyncratic or non-standard notations. Using a type of musicological archeology, I want to contribute to the understanding of gesture, language and communication in Capdeville’s works. I aim to preserve the works, particularly by highlighting the collaborative approach of the composer and proposing ways of establishing a documentation process for these aspects in order to systematise the works. I focus on the use of technology of magnetic tape as both a source of listening (the tapes provide a recording of the entire performance) and an instrument (tape recordings are given parts in the composition of the piece). Technology is also an important analytical tool because it helps to track collaborative creative processes. The iAnalyse software is used to help reconstruct and interpret music theatre works.

This article discusses the role of electroacoustic music practice in the context of human–robot interaction (HRI), illustrated by the first author’s work creating the sonic language of interactive robotic artwork Diamandini. It starts with a discussion of the role of sound in social robotics and surveys various notable conceptual approaches to robot sound. The central thesis of the article is that electroacoustic music can provide a valuable source of aesthetic considerations and creative practice for the creation of richer and more refined sonic HRIs by giving practitioners new ways to create believable sounding objects, to convey fiction, agency and animacy, and to communicate causality in auditory feedback. To demonstrate this, the authors describe the rationale for treating robot sound design as a compositional process and discuss the implications of the endeavour’s non-linear and site-specific nature. These considerations are illustrated using sound examples and design decisions made throughout the creation process of the robotic artwork. The authors conclude with observations on how the compositional process is affected by this particular application context.

This article investigates the use of machine learning within contemporary experimental music as a methodology for anthropology, as a transformational engagement that might shape knowing and feeling. In Midlands (2019), Sam Salem presents an (auto)ethnographical account of his relationship to the city of Derby, UK. By deriving musical materials from audio generated by the deep neural network WaveNet, Salem creates an uncanny, not-quite-right representation of his childhood hometown. Similarly, in her album A Late Anthology of Early Music Vol. 1: Ancient to Renaissance (2020), Jennifer Walshe uses the neural network SampleRNN to create a simulated narrative of Western art music. By mapping her own voice onto selected canonical works, Walshe presents both an autoethnographic and anthropological reimagining of a musical past and questions practices of historiography. These works are contextualised within the practice and theory of filmmaker-ethnographer Trinh T. Minh-ha and her notion of ‘speaking nearby’. In extension of Tim Ingold’s conception of anthropology, it is shown that both works make collaborative human and non-human inquiries into the possibilities of human (and non-human) life.

We propose a conceptual framework for describing and documenting sound installations from a visitor’s point of view. In the form of a taxonomy, the framework includes four complementary perspectives: sound sources, sound design approaches, visiting modalities and visual aspects. Its elaboration was informed by a review of contemporary sound installations in Quebec as well as a literature review on conceptual and theoretical frameworks on sound art and sound installations. Compared with existing frameworks, the taxonomy is useful for describing and comparing sound installations across meaningful perspectives from a visitor’s stance. To illustrate the potential benefits of the taxonomy and the diversity of installations it can portray, we provide a comparative analysis of four contemporary sound installations from different perspectives. We conclude with the use of this taxonomy for documentation purposes.

The fields of media archaeology and data sonification have not been without contestation regarding means and methods. However, in combination, these fields present an opportunity for a novel approach to the creation of media archaeologically informed sound-based art. This article discusses the artistic use of data sonification techniques and the need to balance the musification of data while maintaining a sense of the underlying data. The use of data sonification techniques within media archaeology to facilitate the organisation of sound is briefly discussed. A framework is presented for utilising data sonification to facilitate the organisation of sound within the lens of media archaeology inquiry. Such an approach provides a novel method in media archaeologically informed sound-based art that utilises the sound of the artefact as a method of expression between genealogically related forms of media. A sound installation developed by the authors is presented that critically examines the use of, and gives concrete form to, the framework and the ideas established in this article.

Peter Manning first established an international reputation with his book Electronic and Computer Music, originally published by Oxford University Press in 1985 and now in its fourth edition (Manning 2004). The book presents a detailed account of the technical and creative evolution of electronic music from its earliest days. Starting from Thaddeus Cahill’s 1897 patent application for the Dynamophone, it traces developments in North America and Europe and discusses a range of analogue techniques including tape manipulation and voltage-controlled synthesisers. Later chapters consider the digital revolution that followed, including developments in MIDI and digital workstations. In later editions, the sections on computer music were significantly revised and expanded to reflect the major and rapid transformation of the field. A distinctive feature of the book is the way it combines detailed historical information and thorough explanations of technical developments, often clarified by use of explanatory diagrams, with insightful accounts of the musical repertoire produced using this technology. The book was derived from Peter’s PhD thesis at Durham University in which he surveyed and analysed numerous contemporaneous texts documenting developments in minute detail.
