Through an ecological approach to creative practice (henceforth ecomprovisation), this project deals with the expansion of creative strategies applicable to everyday contexts. Within ubiquitous music (ubimus), we target the convergence of sonification methods with the application of ecological models within the context of comprovisation. These conceptual frameworks inform the technological and aesthetic approaches applied in the making of Markarian 335. We describe the creative procedures and the implications of the design choices involved in this artwork. The contributions and shortcomings of our ecomprovisational approach are situated within the context of the current efforts to foster expanded creative possibilities in ubimus endeavours.

This article explores strategies that allow electronic music performers to engage their audiences and environments in live acts of co-creation. We outline our existing musical practice relying on site-specific sampling and digital mobile technologies that have been tested across a range of participatory music performances. Salient challenges within this performance context are identified and several tools and techniques are proposed as solutions. We then consider how setting-based and sample-based participatory performances can be expanded through gamification strategies. After exploring how notions of playful experience can offer new insights into the nature of audience engagement, we propose several approaches for introducing gamified elements into performative music practices that can expand the scope of audience participation while preserving key aspects of using concert location recordings and musical improvisation. We conclude by discussing the implications of these approaches for the performer–audience relationship and the prospect of musical engagement with the environment before suggesting directions for future research.

This article aims to explore the concept of patched/versioned musical works as creative ecologies. It identifies how the internet’s involvement in music creation and dissemination influences choices related to the release of such works. Throughout this writing, the author looks at the increasingly volatile structures surrounding recorded music in the early twenty-first century as a result of streaming platforms such as Spotify and video-based social media sites such as TikTok becoming the primary means for music consumption. It explores this volatility as a method for approaching the release of new music within dynamic musical ecosystems and looks at the growing art scene focusing on this way of working, drawing parallels between artistry and subscription-based services where content continually evolves over time.

Examining the role of arts and culture in regional Australia often focuses on economic aspects within the creative industries. However, this perspective tends to disregard the value of unconventional practices and fails to recognise the influence of regional ecological settings and the well-being advantages experienced by amateur and hobbyist musicians who explore ubiquitous methods of music creation. This article presents the results of a survey conducted among practitioners in regional Australia, exploring their utilisation of creative technology ecosystems. This project marks the first independent, evidence-based study of experimental electronic music practices in regional Australia and how local and digital resource ecosystems support those activities. Spanning the years 2021 and 2022, the study involved interviewing 11 participants from many Australian states. In this article, we share the study’s findings, outlining the diverse range of experimental electronic music practices taking place across regional Australia and how practitioners navigate the opportunities and challenges presented by their local context.

This article describes the ways in which the spectra of electroacoustic music compositions can be structured coherently. It begins by describing the straightjacket that composers and listeners are constrained by when using the concept of ‘source bonding’ and how this needs to be discarded for effective listening. It then describes the concept of spectral merging and how ideas of musical timbre are formed, and finally discusses the many ways that spectra can be structured with both harmonic and inharmonic components. Examples are given from the author’s own music and other well-known works in the literature of electroacoustic music.

This article introduces the history and aesthetics of feedback-based music, from early practitioners to more advanced methods and state-of-the-art works based on adaptation. Some of the most relevant techniques developed over almost six decades of investigations in the area of recursive systems for electronic music are discussed to show the variety and richness that a single specialised domain can have, providing examples of how scientific and philosophical principles can be translated into music. The historical context is key to understanding the evolution of the field: feedback-based music arose during the same years in which cybernetics, together with other disciplines, were experiencing a profound transformation. I will provide an overview of how such disciplines changed, highlighting the connections between seemingly distant areas such as philosophy, biology and engineering, and the fact that the development of feedback-based music appears to have followed somewhat closely the evolution of systems thinking. Finally, the article explores questions of musical aesthetics and music theory related to the use of complex autonomous systems in live performance through observations on the author’s creative practice.

This article fragments and processes Debris, a project developed to formalise the creative recycling of digital audio byproducts. Debris began as an open call for electronic compositions that take as their point of departure gigabytes of audio material generated through training and calibrating Demiurge, an audio synthesis platform driven by machine learning. The Debris project led us down rabbitholes of structural analysis: what does it mean to work with digital waste, how is it qualified, and what new relationships and methodologies do this foment? To chart the fluid boundaries of Debris and pin down its underlying conceptualisation of sound, this article introduces a framework ranging from archaeomusicology to intertextuality, from actor-network theory to Deleuzian assemblage, from Adornian constellation to swarm intelligence to platform and network topology. This diversity of approaches traces connective frictions that may allow us to understand, from the perspective of Debris, what working with sound means under the regime of machine intelligence. How has machine intelligence fundamentally altered the already shaky diagram connecting humans, creativity and history? We advise the reader to approach the text as a multisensory experience, listening to Debris while navigating the circuitous theoretical alleys below.

Perceived relationships between timbres are critical in electroacoustic music. Most studies assume timbres have fixed inter-relationships, but we tested whether distinct tasks change these. Thirty short sounds were used, from five categories: acoustic instruments, impulse responses, convolutions of the preceding, environmental sounds and computer-manipulated instrumental sounds. In Task 1, 46 non-musicians formed a ‘cohesive’ sonic ordering of unlabelled icons (sounds attached). In Task 2, they categorised the icons into four boxes. In Task 3 listeners separately ordered the sounds from each of Task 2’s boxes using the approach of Task 1. Tasks 1 and 2/3 revealed distinct orderings, consistent with conceptual flexibility. To analyse the orderings, we replaced conventional distance by adjacency measures, and described each system as a network (rather than spatial positions), confirming that the two task outcomes were distinct. Network analyses also showed that the two systems were mechanistically distinct and allowed us to predict temporally changing networks, modelling the observed networks as successive perceptions. Further simulated networks generated with the temporal model readily encompassed all possible pairings between the sounds and not just those we observed. The temporal network model thus confirms conceptual flexibility even in untrained listeners, clearly suitable for a composer to use.
