Digital games are a fertile ground for exploring novel computer music applications. While the lineage of game-based compositional praxis long precedes the advent of digital computers, it flourishes now in a rich landscape of music-making apps, sound toys and playful installations that provide access to music creation through game-like interaction. Characterising these systems is the pervasive avoidance of a competitive game framework, reflecting an underlying assumption that notions of conflict and challenge are somewhat antithetical to musical creativity. As a result, the interplay between competitive gameplay and musical creativity is seldom explored. This article reports on a comparative user evaluation of two original games that frame interactive music composition as a human–computer competition. The games employ contrasting designs so that their juxtaposition can address the following research question: how are player perceptions of musical creativity shaped in competitive game environments? Significant differences were found in system usability, and also creativity and ownership of musical outcomes. The user study indicates that a high degree of musical control is widely preferred despite an apparent cost to general usability. It further reveals that players have diverse criteria for ‘games’ which can dramatically influence their perceptions of musical creativity, control and ownership. These findings offer new insights for the design of future game-based composition systems, and reflect more broadly on the complex relationship between musical creativity, games and competition.

Mapping concerns the connection between gestures, or structures and audible results in a musical performance or composition. While this is of intense interest to performers of new instruments and instrument designers, it has also been an area of interest for some composers. Algorithmic composition is sometimes the process of imagining a gesture or structure - perhaps physical or visual - and then applying a mapping process to turn that ‘gesture’ of the conceptual domain into sound which may display the original conception in some way. This article looks at mapping from the point of view of algorithmic composition, particularly where persistence is an issue, such that the gesture (conceptual domain) is embodied and perceptible in the musical result.

This article provides a brief survey of composition in which field recordings or other referential sounds are transcribed for acoustic instruments. Through a discussion of how electroacoustic music and scholarship have conceptualised the notion of mimesis, and how various forms of contemporary acoustic music have adopted electroacoustic techniques, it identifies a recent musical practice in which these concerns are brought together. The article proposes the term mimetic instrumental resynthesis as a way of describing the common threads behind works that employ electronic-assisted or computer-assisted techniques towards instrumental imitations of environmental and extra-musical sounds. The article also highlights some of the conceptual and aesthetic questions emerging from such a practice, including the idea of transformation, issues of referentiality, listening, the influence of different technologies and their aesthetic implications, and the tension between abstract and concrete conceptions of the works discussed. Finally, the article raises concerns surrounding the language of discussing what is necessarily an interdisciplinary venture.

As the techniques used in creating audio art and electronic music become more diversified and increasingly use some sort of computer-oriented notation, the question of analysis of this wide repertoire is revisited. While there are still many obstacles in its study, this topic attracts more attention today than in the recent past. In this article, I emphasise the need to consider that, when analysing audio art and electronic music, technology, technique and musical style are to be taken in account. To this end, I introduce concepts put forth by the Russian Constructivists as a basis for reflection.

This article investigates the essential association between location and sound, mediated and represented by the process of recording and the subsequent creation of an artwork. The basic argument this article would like to develop is that location-specific sound recording, as practised by artists and phonographers, is basically an exercise in disembodiment of sound from environment, whether it is observational or immersive in approach; if the purpose of this mediation by recording is artistically reconstructive, the location-specificity of the recorded sound is displaced by the further mediation of the creative process. By developing the argument from an experimental angle, in relation to an audio art project Landscape in Metamorphoses, this article will try to examine how the discourse of acoustic ecology becomes reconfigured in the shift from environmental sound content recorded at location to production of soundscape composition as audio artwork. Today, the application of digital media to artistic practice has become integral – in the case of audio art via creation of auditory art works (for both spatial diffusion and live interaction); this can bring about a reconfiguration of environmental aesthetics. The article will find relevance in redesigning the ecological discourse in the digital realm of ‘soundscaping’ through the practice of mediation, as composing of the sound of location, or ‘place’.

The musicologist is confronted with many situations during the analysis of electroacoustic music, whether on support media, mixed, or real-time. Musical genres and styles vary greatly, and the collection of electronic musical instruments has also proven to be very heterogeneous. The intrinsic characteristics of the electroacoustic parts and their scoring create serious limitations. Furthermore, many sources remain inaccessible or are already lost. Thus the preoccupation with documentary sources related to the acts of creation, interpretation, and technological context becomes more and more pressing. It is now essential to formulate a synthetic vision of this music, which has existed for half a century, and to pursue the search for invariants. This work must be based on a rigorous methodology that has yet to be developed. More generally speaking, the goal is to establish the terms and conditions of a systematic musicology of electroacoustics.

This article explores the concept of sonic image in acousmatic music. Such a concept is understood as mental representations motivated by sonic stimuli that reach the listener in an acousmatic listening situation and that can be determined by a focus on either the intrinsic or extrinsic aspects of the sounds – or even a combination of both. The intrinsic aspects are related to the inner characteristics of the sounds and are, therefore, accessed through reduced listening. They are not dependent on the identification of the sources that caused the sounds or possible meanings and connotations conveyed by them. The extrinsic aspects, on the other hand, are the connotations, meanings and references that lay outside the sounds themselves and that can be related to human experience in a broader sense, including domains other than the sonic. Since sonic images are not exclusively dependent on intrinsic factors, they can be the result of various kinds of listening attitudes not restricted to reduced listening. The article highlights the links between ideas presented by different authors who approach the issue of sonic image or who present considerations on other issues that may inform an understanding of sonic image in the acousmatic context. Since sonic image is dependent both on the intrinsic and the extrinsic aspects of sound, it is argued that it is a concept that can integrate (and possibly unify) different approaches related to acousmatic listening. The considerations on sonic image presented here touch issues regarding different listening attitudes, the relationships between sound and source, and links between sound and gesture, amongst other aspects. The approach taken here is focused as much as possible on the perspective of the listener rather than on the composer, although some considerations related to compositional thinking are occasionally exposed.

Discussing listeners and their listening process in electroacoustic music has always been a difficult task because of the apparent subjectivity of listening. If we understand, however, that listening is a phenomenal process, the subjectivity of listening should be considered an important and crucial factor that can be discussed and explained by phenomenological approaches. This paper first conducts a brief survey of some electroacoustic music and observes primary sound-images – body, place and their negations – that emerge from the phenomenological approaches. The observation of the emergence of these primary sound-images then leads us to consider two listening processes, perceiving and imagining, that act as the main correlates of the listening process in which listeners engage with electroacoustic music. This paper also discusses the phenomena of sound-images, the product of the two listening processes, and explains what we as listeners imagine and how we imagine when we listen to electroacoustic music. Finally, the paper examines the properties of body and place as sound-images and how these sound-images are negated in imaginal listening of electroacoustic music.

This article discusses the compositional strategies of turntablist DJs working within the hip-hop genre, focusing on processes developed by these musicians such as mixing, scratching and beat juggling, all of which are carried out on turntables. Since the development of the gramophone at the turn of the century, the turntable has become an instrument of creation as well as reproduction, resulting in the ground-breaking compositional strategies of hip-hop music. Hip-hop DJs create original music from a range of existing musical texts and in doing so, raise questions concerning originality and authorship as well as questioning the division between composer and performer. Hip-hop music is regarded by authors such as Poschardt (1998) as one of the final avant-gardes of the twentieth century; this article will explore and discuss the ground-breaking nature of the genre with reference to new compositional strategies and the turntable technology with which they are carried out.

The capacity for electroacoustic music to project and manipulate sonic images is now acknowledged as a cornerstone of the medium's aesthetic potential. The notion of imagery may be used in a range of ways, reflecting electroacoustic music's potential to present sound ‘documents’ re-contextualised from real-world experience, as well as to project more abstract entities in which the concept of an image may give coherent form to fantastical constructs, frequently driven by the transforming and distortive effects of signal processing. This paper investigates the practical application of these distinctions in electroacoustic music, largely through reflective discussion of the author's own working methods, and evaluates ways in which the aesthetic effects of signal processing can influence the nature and construction of sound images. Within this, Denis Smalley's concept of the indicative field is used as a conceptual tool for the characterisation and analysis of the affective dimensions of sound image construction and manipulation.

This article explores listening and communications strategies that arise with a collaborative scoring system we are developing for use within improvisational contexts. Performers generate notation on a scrolling score a short time before it is played or rendered into sound. Working a short time in the future allows performers to respond to sound as they would in any improvisatory situation, and yet coordinate their activity through notation in a way typically associated with pre-composed music. The ‘Anticipatory Score’ platform supports the exploration of different kinds of relationships between performers, composers and audience members, and different listening and engagement strategies that affect the musical experience for all participants.

The expression gestural mapping is well imbedded in the language of instrument designers, describing the function from interface control parameters to synthesis control parameters. This function is in most cases implicitly assumed to be instantaneous, so that at any time its output depends only on its input at that time. Here more general functions are considered, in which the output depends on the history of input, especially functions that behave like physical dynamic systems, such as a damped resonator. Acoustic instruments are rich in dynamical behaviour. Introducing dynamics at the control stage of an electronic instrument can help compensate for lack of dynamics in later non-physical synthesis stages. A broadening of the function space offers new aesthetic possibilities for composing instruments. Examples are presented to illustrate the new design/composition mode as well as practical techniques. In this context, it is suggested that the word mapping be updated with the more descriptive expression dynamic control processing.

This article proposes a narrative theory thought in terms that are specific to sound practice. It addresses two different fields – Acousmatic Music and Foley Art – as a possibility of understanding sound narration and conceptualising it around the idea of fiction. To this end, it begins from the concepts of sound-motif, sound-prop and sound-actors, in order to propose a dramaturgic practice specific to sound terms.

The theory of sound dramaturgy acquires a practical outline by making use of multichannel constellations as a composition strategy, with specific loudspeaker arrangements. The theory advocates loudspeakers as the mediators of the experience and the stage as part of the audience’s assembly. This translates into a practice of staging sound fiction, which focuses on formulating a conjecture based on formal and factual structures, allowing for a direct relationship between the listener and the listening, between the sounds and their fictional location.

A corpus of historical electronic art music is available online from the UbuWeb art resource site. Though the corpus has some flaws in its historical and cultural coverage (not least of which is an over-abundance of male composers), it provides an interesting test ground for automated electronic music analysis, and one which is available to other researchers for reproducible work. We deploy open source tools for music information retrieval; the code from this project is made freely available under the GNU GPL 3 for others to explore. Key findings include the contrasting performance of single summary statistics for works versus time series models, visualisations of trends over chronological time in audio features, the difficulty of predicting which year a given piece is from, and further illumination of the possibilities and challenges of automated music analysis.

Approaches to the multichannel spatialisation of electroacoustic music are described here with reference to musical case studies which focus upon the expressive functions of space and the theatricality of sound diffusion in an acousmatic context. A site-specific approach to spatialisation is proposed to enhance theatrical aspects of musical performance. Case studies include proposals for novel layouts of the diffusion system within the performance space and compositional techniques that are designed to re-evaluate our understanding of individual listening spaces.

I have had a major interest in the performance practice issues in electronic and interactive systems over the years (see, for example, Kimura 1996). As a performer/composer often presenting pieces from the classical and other contemporary acoustic violin literature in traditional settings along with electronic works, and also as a teacher of interactive computer music performance at a conservatory where my students include highly trained performers, performance practice issues in computer music come up very frequently in association with the creative process. I tend to focus on creating MaxMSP patches that address a particular musical context or situation, rather than creating an elaborate versatile and reusable MaxMSP patch and then using that patch in a particular way to make music. This paper describes a few examples of my interest in this area: (i) System Aspects: Performance Practice Issues and Room Acoustics; (ii) ‘Pragmatic’ Programming and Performance of Interactive Music; and (iii) Creative Process and Interactive Computer Music.

The conceptual starting point for an ‘action–sound approach’ to teaching music technology is the acknowledgment of the couplings that exist in acoustic instruments between sounding objects, sound-producing actions and the resultant sounds themselves. Digital music technologies, on the other hand, are not limited to such natural couplings, but allow for arbitrary new relationships to be created between objects, actions and sounds. The endless possibilities of such virtual action–sound relationships can be exciting and creatively inspiring, but they can also lead to frustration among performers and confusion for audiences. This paper presents the theoretical foundations for an action–sound approach to electronic instrument design and discusses the ways in which this approach has shaped the undergraduate course titled ‘Interactive Music’ at the University of Oslo. In this course, students start out by exploring various types of acoustic action–sound couplings before moving on to designing, building, performing and evaluating both analogue and digital electronic instruments from an action–sound perspective.

The design and construction of an organised sound space to support information representations in the human–computer interface is described. The design of the sound space is guided by four principles which match perceptual structure with data structure to improve natural comprehension of an auditory display. These principles – completeness, comprehensibility, consistency, and cohesiveness – have been generalised from the use of colour displays in scientific visualisation. The choice of perceptual parameters to represent different types of data is informed by the body of psychoacoustic literature. The raw material for the construction of the sound space is the McGill University Master Samples (MUMS) palette of musical instrument samples. This is an important choice because this reference resource enables reproduction and confirmation of the results. The construction was carried out in four stages – the ‘pedestal’, the ‘skin’, the ‘skeleton’ and the ‘flesh’. The pedestal consists of eight equally discriminable timbres organised in a circle by perceptual similarity. The skin is the boundary of variation in the space, defining the limits of dynamic range for pitch and brightness at each timbre. The skeleton characterises the internal behaviour of the space at a number of perceptually measured points. The flesh is a continuous medium moulded to the skeleton and skin, realised by a three-dimensional (3D) regularised linear spline interpolation. The concrete realisation of the sound space can be investigated through a user interface, called the GamutExplorer. Colour visualisations of slices and wireframe views of the 3D space can be chosen, and sounds can be picked with a mouse.

This article aims to sketch a theory of sound sculpture, one that would explain the variety of forms this artistic practice might take on and define it in relation to other art forms. My hypothesis is that in order to do this we must focus on the traits of sound sculpture connecting it to music rather than on those separating the two. A useful instrument to analyse this connection is Harry Partch’s concept of corporeal music. In contrast to Western classical music, which he viewed as abstract and devoid of life, Partch envisioned a music that would emphasise the physicality of sound-making and engage the listener on a more visceral level. Investigating a number of works from all parts of the sound sculpture spectrum, I argue that all the various practices that comprise the art form present the core traits of Partch’s musical ideal (physicality of music, audience engagement, and unity of the sonic and the visual) to a substantial extent. Analysing sound sculpture in light of its connection to music brings to the fore a number of musical issues for which this new art form provides a new perspective. Among these are the agency of the composer and the listener, the function and nature of a score, as well as the role of technology in music-making. These issues, along with the general idea of corporeality of music, compose a discourse that transcends the boundaries of different subgenres of sound sculpture, allowing for theorisation of the art form as a whole.
