Abstract [en]

This doctoral project is grounded in my own practice as a professional clarinettist and situated within the field of artistic research. The aim is to design electro-acoustic instrumental systems that enable similar complexity, proprioceptive feedback and artistic depth as in the interaction between a performer and an acoustic instrument. Three research questions guide the project: 1) What is required in the design of an electro-acoustic instrumental system to enable the creation of musical works which display complexity, feedback and artistic depth in the interplay between the performer and the system? 2) How can a multimodal understanding of musical gesture contribute to the design of an interactive electro-acoustic instrumental system? 3) How can the affordances of interactive systems for music performance be artistically exploited, explored and analysed through artistic collaborations and reflexive methods?

Three longitudinal artistic laboratories have served as the sites for the exploration of electro-acoustic instrumental systems that I have designed and utilised in my artistic practice: The first focuses on performer-instrument relations in gestural space, and how resistance, affordances, and interaction can be integrated into EAI systems. The second explores artistic approaches for remote distributed interaction among musicians, instruments, and performance environments. The third investigates how expressive musical gestures can be analysed, modelled, and transformed into forms of agency within EAI and AI-augmented musical systems. Together, these laboratories explore different aspects of embodiment, agency, collaboration, and interaction design in EAI systems.

Performing with EAI systems requires a close relationship with, and an intimate understanding of the system, as well as the specific relationship between the performer’s body and the sound-producing techniques and technologies employed. The exploratory nature of the project moves forward in an iterative process in which designing and performing within these systems develop in parallel with observational and reflexive analysis. Stimulated recall analysis has served as the primary reflexive methodology. However, because a significant part of musical performance operates through the body schema and therefore remains inaccessible to conscious reflection, stimulated recall alone cannot account for all the experiential dimensions of performance. For this reason, a series of quantitative methods have complemented the qualitative approaches. As the project developed, the combination of methods became more elaborate, introducing machine learning and Laban Effort analysis in real-time to detect and model expressive gesture. Hereby, a deeper understanding of how gestures carry musical meaning was also transferred to embodied music performance in the EAI systems.

Across all three laboratories, the most successful artistic scenarios were those where the systems remained responsive yet capable of surprise, offering the performer neither full control nor complete unpredictability. The EAI systems became spaces for negotiation, where expressive gestures, listening strategies, instrumental affordances, technological processes, and the actions of both human and non-human actors continuously interacted and influenced each other to shape musical outcomes. Over time, these systems shifted from mere instruments to collaborators, and from design objects to active participants in the creation of music.

The main contribution of this thesis is a framework for understanding EAI systems through the interconnected manifestations of resistance, affordances, expressive gestures, and agency. From this viewpoint, designing EAI systems is not just a technical task but an artistic process of shaping relationships between performers, technologies, and sounds. It is through these relationships and the tensions they create that new forms of musical expression emerge.

Abstract [en]

Musical performance is a multimodal experience, for performers and listeners alike. This paper reports on a pilot study which constitutes the first step toward a comprehensive approach to the experience of music as performed. We aim at bridging the gap between qualitative and quantitative approaches, by combining methods for data collection. The purpose is to build a data corpus containing multimodal measures linked to high-level subjective observations. This will allow for a systematic inclusion of the knowledge of music professionals in an analytic framework, which synthesizes methods across established research disciplines. We outline the methods we are currently developing for the creation of a multimodal data corpus dedicated to the analysis and exploration of instrumental music performance from the perspective of embodied music cognition. This will enable the study of the multiple facets of instrumental music performance in great detail, as well as lead to the development of music creation techniques that take advantage of the cross-modal relationships and higher-level qualities emerging from the analysis of this multi-layered, multimodal corpus. The results of the pilot project suggest that qualitative analysis through stimulated recall is an efficient method for generating higher-level understandings of musical performance. Furthermore, the results indicate several directions for further development, regarding observational movement analysis, and computational analysis of coarticulation, chunking, and movement qualities in musical performance. We argue that the development of methods for combining qualitative and quantitative data are required to fully understand expressive musical performance, especially in a broader scenario in which arts, humanities, and science are increasingly entangled. The future work in the project will therefore entail an increasingly multimodal analysis, aiming to become as holistic as is music in performance.

Abstract [en]

Instrument design is not just a matter of hardware, it also concerns strategies for software mapping of input to output data. I will in this paper report on how an augmented clarinet that I, together with a team at LTU began developing in 2015 has continued to develop over the past seven years. The focus will be on the development of artistic applications within the system. Performers frequently describe the resistance of their instrument as a manifestation of the challenges they encounter when playing. One can argue that the goal of a skilled performer is to get rid of resistance, but it is in fact a central part of the relationship between performer and instrument. Acquiring technique and skill seems to be a way for the performer not to overcome resistance but to learn how the instrument responds to force. Realizing the importance of resistance in the artistic process we need to ask ourselves; how can we use this knowledge when creating new instruments? Returning to video documentation of performances with two different mappings and through stimulated recall analysis I seek a deeper understanding of how software, mapping and performance practice interacts, forming the basis of the artistic expression.

Abstract [en]

Recent developments in artificial intelligence (AI) have been increasingly driven by technoscientific and corporate approaches that emphasise large-scale datasets and autonomous generation systems. In response, Human-Centred AI proposes an alternative framework foregrounding human agency, values, and creative control. This paper contributes to this discourse by examining collaborative performance with AI-augmented instruments through a practice-led experiment involving two musicians. In this way, we investigate how musical agency is distributed across humans and multiple AI systems. Conducted through a laboratory process leading up to a live performance, this project went through five phases: 1) introduction of interfaces, 2) curation of datasets, 3) training of neural audio synthesis models and applying corpus-based synthesis techniques, 4) working with the intelligent instruments in rehearsals and performance, and 5) analysing the outcomes. Through combining qualitative, phenomenologically grounded methods and practice-led artistic exploration, we identify emergent creative relationships between performers and AI-augmented instruments. By analysing the agency at play, we unpack how creative control is distributed between human and machine. Situating our work within the framework of professional collaborative performance, we address the lack of phenomenological research into intelligent instruments whilst contributing methodologies for accountable, artist-centred AI development in musical contexts.

Abstract [en]

This article presents a study that applies Laban’s Effort theory to detect a musician’s expressive intentions during performance. Laban Effort theory was chosen for its capacity to support the observation, description, and interpretation of expressive movement. The aim was to develop interactive musical systems that learn from the embodied expressivity musicians cultivate through practice. The study adopts a multidisciplinary approach, combining Laban Motion Analysis with interactive machine learning. Gesture data, audio, and video were recorded during a performance of Brahms’s Clarinet Sonata Op. 120 No. 2. The video was then analysed by an expert annotator observing Laban Efforts. The annotated video was then reviewed in collaboration with the performer to incorporate Effort Phrasing that reflects changes in intensity within Efforts. The annotations were then used as training data, together with motion data recorded during the performance, to train a regression model. The model was evaluated against expert annotations and through qualitative video analysis. Unlike the very linear notation of a Laban analyst, the model reflects the dynamism of human motion by capturing the almost humanly unobservable nuances in Effort variations. This points to the possibility of using machine learning models to reflect a performer’s expressive intentions in real-time.
