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.

This article discusses the importance of active listening when engaging new audiences with experimental and unfamiliar musical formats. Spatial music is examined as a physically immersive medium in which the audience is implicated as an active component in the execution of its performance. A brief account of the historic context of spatial music will be presented alongside speculation for the trajectory of its future; particularly its potential as a model for audience engagement. This article will first consider how spatially immersive performances have the capacity to activate listeners and how can this help to engage new audiences with new ways of listening. It will also question the notion of inhabiting spatial music, with an investigation of the multiple ways in which spatial music relates to physical space and the terms of its inhabitation. The concept of virtual listening will be discussed in response to trends towards passive hearing, as driven by recent technological developments in acoustic software and hardware, and the resultant abstraction of the spatial and social dynamics of sound in virtual space. The physiological and psychological differences between listening and hearing will also be examined as a means of establishing fundamental differences in the ways that we interact with music, and questioning what our listening habits tell us about audience engagement in the context of experimental music performance. This article will also question the individual roles of the musician, composer, architect/designer and audience in the ongoing responsibility to improve audience engagement in new, or unfamiliar musical works. Importantly, this article will also explicitly examine who we are referring to when we use the term ‘new audiences’. Major developments in acoustic technology during the last few decades have somewhat confused the diagram between music, space and listener. The understanding of which elements are active and which are passive is especially ambiguous at a time when ambisonic and binaural technologies have become developed enough to provide accurate simulations of the abstract, acoustic qualities of spaces, but on virtual terms. Architects, composers, musicians, engineers and audiences are at a crossroads in the development of new music and experimental, spatiosonic practice. ‘Spatiosonic’ is a hybrid term which is used throughout this article to describe work and phenomena which regard space (spatio) and sound (sonic) as equal, interactive partners. This article considers some of the opportunities and limitations at stake in current techniques of composition, performance and listening.

Sonification presents some challenges in communicating information, particularly because of the large difference between possible data to sound mappings and cognitively valid mappings. It is an information transmission process which can be described through the Shannon-Weaver Theory of Mathematical Communication. Musical borrowing is proposed as a method in sonification which can aid the information transmission process as the composer’s and listener’s shared musical knowledge is used. This article describes the compositional process of Wasgiischwashäsch (2017) which uses Rossini’s William Tell Overture (1829) to sonify datasets relating to climate change in Switzerland. It concludes that the familiarity of audiences with the original piece, and the humorous effect produced by the distortion of a well-known piece, contribute to a more effective transmission process.

Sixty years on from Pierre Schaeffer’s call for ‘primacy of the ear’ (primauté de l’oreille), this article asks an ostensibly simple question: whose ear/aural perception is being referred to when we talk of and compose under this guiding principle? Is there a tacit preselected audiometric norm or even a pair of golden ears, at its core? The article will problematise the uncompromising modernist notion espoused by Babbitt of a ‘suitably equipped receptor’ (Babbitt 1958), and posit examples of well-known composers whose hearing markedly diverged from the otologically normal, an acoustics standard from which A-weighted decibels is predicated (ISO 226:2003). In conclusion the concept of auraldiverse hearing is proposed and creative strategies that eschew or problematise auraltypical archetypes in sonic arts practice and theory wherever they may lie are encouraged.

This article aims to reflect on the main constraints encountered in recovering music-theatre works that involve a variety of diverse aspects that are relevant to their performance. As well as the score, scripts or other additional documents, the works considered here also include electroacoustics recorded on magnetic tape, consequently requiring specific approaches in order to preserve such kinds of works. Video recordings of concerts are important for understanding, documenting and eventually restaging these works. This idea is not new; audio-video recordings have for many years served as sources for documenting live performances (music-theatre or art performances). However, it is still important to discuss just how and with which tools these very important documents might be preserved and exploited. Hence, the study of the structure of Molly Bloom and FE…DE…RI…CO…, both with music by Constança Capdeville, enables an understanding of the processes in which documentation is relevant to preserving such a valuable cultural heritage.

This article begins with an outline of the Manovich general definition of borrowing followed by an introduction to the theme of borrowing in music, particularly within the context of acousmatic music. Two scenarios proposed by Navas in his taxonomy of borrowing are used to further the discussion in relation to material sampling and cultural citation. With reference to material sampling, some examples of remix, appropriation and quoting/sampling taking place within acousmatic music are highlighted. With regards to cultural citation, two levels of reference will be considered: cultural citation from sound arts, that is, intertextuality, and cultural citation from other media, that is, intermediality. The article closes with some reflections a posteriori about my own composition, Variation of Evan Parker’s Saxophone Solos, and how this relates to wider notions of musical borrowing.

This article explores the accessibility of acousmatic compositional approaches to sound and installation art. Principally of concern is the consideration of intimacy to create a means of ‘connecting’ with an audience. Installations might be said to explore ideas of intimacy in two ways which increase accessibility for the installation visitor: through cultivating installation–visitor relationships, and through encouraging visitor–visitor relationships. A variety of ways in which various acousmatic compositional techniques relating to intimacy might be brought to bear on and operate as a way of drawing a listener into a work are explored, in particular as they relate to the consideration of space and spatial relationships. These include recording techniques, types of sound materials chosen, and the creation of particular spatial environments and listening conditions. Along with a number of instances of sound art provided by way of examples, my ongoing GRIDs series of sound sculptures will provide a case study of works related to an acousmatic aesthetic where these concerns find an outlet.

Analysing electroacoustic music is a challenging task that can be approached by different strategies. In the last few decades, newly emerging computer environments have enabled analysts to examine the sound spectrum content in greater detail. This has resulted in new graphical representation of features extracted from audio recordings. In this article, we propose the use of representations from complex dynamical systems such as phase space graphics in musical analysis to reveal emergent timbre features in granular technique-based acousmatic music. It is known that granular techniques applied to musical composition generate considerable sound flux, regardless of the adopted procedures and available technological equipment. We investigate points of convergence between different aesthetics of the so-called Granular Paradigm in electroacoustic music, and consider compositions employing different methods and techniques. We analyse three works: Concret PH (1958) by Iannis Xenakis, Riverrun (1986) by Barry Truax, and Schall (1996) by Horacio Vaggione. In our analytical methodology, we apply such concepts as volume and emergence, as well as their graphical representation to the pieces. In conclusion we compare our results and discuss how they relate to the three composers’ specific procedures creating sound flux as well as to their compositional epistemologies and ontologies.

This article focuses on the analysis of computer music, that is, music which uses programming languages so that what the listener hears is the result of computer code. One key point in this article is that this music exists with some writing, that is, the computer code. I note that this key point has not been addressed in the latest theories for analysing computer music. Indeed, we often see this music as part of the electroacoustic field, where the audio signal is essential, and where we usually read that those musics are non-written music. After an introduction on this topic, in the second section I will make a distinction between ‘before the signal’ and ‘from the signal’ to organise the theories to analyse electroacoustic music. In the third section, I will focus on computer music and I will show the historical difficulty in considering ‘code’ in musical analysis, mainly with an important exchange between two pioneers, Marco Stroppa and Jean-Claude Risset. In the fourth section I will explain with Jean-Claude Risset and Horacio Vaggione the specificity of computer music: this music is written. Finally, I will look into a recent analysis theory, the Interactive Aural Analysis by Michael Clarke, which seems to fit with the latter specificity.

This article proposes a conception of sound as the material of artistic experimentation. It centres on a discussion of the nature of sound’s ontological status and aims to contribute to a new understanding of the role of materiality in artistic practices. A central point of discussion is Pierre Schaeffer’s notion of the sound object, which is critically examined. The phenomenological perspective that underlies the concept of the sound object depicts sound as an ideal unity constituted by a subject’s intentionality. Thus, it can barely grasp the physicality of sounds and their production or their reality beyond individual perception. This article aims to challenge the notion of the sound object as a purely perceptual phenomenon while trying to rethink experimentation as a practical form of thought that takes place through interacting with sonorous material. Against the background of recent object-oriented and materialist philosophical theories and by drawing on the Heideggerian concept of the thing and Gilbert Simondon’s theories of perception and individuation, this article strives to outline a conception of sound as a non-symbolic otherness. The proposed idea of thingness revolves around a morphogenetic conception of the becoming of sonorous forms that links their perception to their physicality.
