  This chapter presents a pedagogical approach based on the author’s experience teaching interactive music technology design from an embodied music cognition perspective. The “musicking quadrant” is introduced as a framework to understand the experiences of those who make music in real-time (performers) and non-real-time (instrument makers, composers, producers), and those who experience music in real-time (perceivers) and non-real-time (analysts). New technologies challenge these roles and allow for new types of musical engagement that align with the 4E cognition perspectives.

  This study aims to use supervised learning – specifically, support vector machines – as a tool for a music mood classification task. Four audio and MIDI datasets, each containing over four hundred files, were composed for use in the training and testing processes. Mood classes were formed according to the valence-arousal plane, resulting in the following: happy, sad, relaxed, and tense. Additional runs were also conducted with the linear discriminant analysis, a dimensionality reduction technique commonly used to better the performance of the classifier. The relevant audio and MIDI features were carefully selected for extraction. MIDI datasets for the same music generated better classification results than corresponding audio datasets. Furthermore, when music is composed with each mood associated with a particular key instead of mixed keys, the classification accuracy is higher.

  With the ever-increasing prevalence of technology, its application in various music-related processes, such as music composition and performance, has become increasingly prominent. One fascinating area where technology finds utility is in music performance, offering opportunities for extensive sound exploration and manipulation. In this paper, we introduce an approach utilizing SuperCollider and Open Sound Control (OSC) commands in a multi-speaker setup, enabling spatial audio control for a truly interactive audio spatialization experience. We delve into the musicological dimensions of these distinct methods, examining their integration within a live performance setting to uncover their artistic and expressive potential. By merging technology and musicology, our research aims to unlock new avenues for immersive and captivating musical experiences.

  The paper presents a study of the noise level of accelerometer data from a mobile phone compared to three commercially available IMU-based devices (AX3, Equivital, and Movesense) and a marker-based infrared motion capture system (Qualisys). The sensors are compared in static positions and for measuring human micromotion, with larger motion sequences as reference. The measurements show that all but one of the IMU-based devices capture motion with an accuracy and precision that is far below human micromotion. However, their data and representations differ, so care should be taken when comparing data between devices.

A systematic review of the last year’s conference proceedings reveals that most papers do, indeed, present new instruments, interfaces, or pieces of technology. Comparably few papers focus on the prolongation of existing NIMEs.

We discuss how focusing more on these four types of NIME development and engagement can be seen as an approach to increase sustainability.

Springer Nature. ISSN 978-3-031-15019-7. Vis sammendrag

  In this project, we propose an algorithm to convert musical features and structures extracted from monophonic MIDI files to tactile illusions. Mapping music to vibrotactile stimuli is a challenging process since the perceptible frequency range of the skin is lower than that of the auditory system, which may cause the loss of some musical features. Moreover, current proposed models do not warrant the correspondence between the emotional response to music and the vibrotactile version of it. We propose to use tactile illusions as an additional resource to convey more meaningful vibrotactile stimuli. Tactile illusions enable us to add dynamics to vibrotactile stimuli in the form of movement, changes of direction, and localization. The suggested algorithm converts monophonic MIDI files into arrangements of two tactile illusions: “phantom motion” and “funneling”. The validation of the rendered material consisted of presenting the audio rendered from MIDI files to participants and then adding the vibrotactile component to it. The arrangement of tactile illusions was also evaluated alone. Results suggest that the arrangement of tactile illusions evokes more positive emotions than negative ones. This arrangement was also perceived as more agreeable and stimulating than the original audio. Although musical features such as rhythm, tempo, and melody were mostly recognized in the arrangement of tactile illusions, it provoked a different emotional response from that of the original audio.

  This paper describes the development of two musical instrument prototypes developed to explore how non-haptic music technologies can be accessed from a web browser and how they can offer accessibility for people with low fine motor skills. Two approaches to browser-based motion capture were developed and tested during an iterative design process. This was followed by observational studies of two user groups: one with low fine motor skills and one with normal motor skills. Contrary to our expectations, we found that avoiding the use of buttons and mice did not make the apps more accessible for the participants with low fine motor skills. Furthermore, motion speed was considered more important for people with low motor skills than the size of the control action. The most important finding is that browser-based musical instruments using sensor-based and video-based motion tracking are not only feasible but allow for reaching much larger groups of people than previously possible. This may ultimately lead to both more personalized and accessible musical experiences.

  Music researchers work with increasingly large and complex data sets. There are few established data handling practices in the field and several conceptual, technological, and practical challenges. Furthermore, many music researchers are not equipped for (or interested in) the craft of data storage, curation, and archiving. This paper discusses some of the particular challenges that empirical music researchers face when working towards Open Research practices: handling (1) (multi)media files, (2) privacy, and (3) copyright issues. These are exemplified through MusicLab, an event series focused on fostering openness in music research. It is argued that the "best practice" suggested by the FAIR principles is too demanding in many cases, but "good enough practice" may be within reach for many. A four-layer data handling "recipe" is suggested as concrete advice for achieving "good enough practice" in empirical music research.

The toolbox includes video visualization techniques such as creating motion videos, motion history images, and motiongrams. These visualizations allow for studying video recordings from different temporal and spatial perspectives. The toolbox also includes basic computer vision methods, and it is designed to integrate well with audio analysis toolboxes. The MGT was initially developed to analyze music-related body motion (of musicians, dancers, and perceivers) but is equally helpful for other disciplines working with video recordings of humans, such as linguistics, pedagogy, psychology, and medicine.

  A techno-cognitive look at how new technologies are shaping the future of musicking. “Musicking” encapsulates both the making of and perception of music, so it includes both active and passive forms of musical engagement. But at its core, it is a relationship between actions and sounds, between human bodies and musical instruments. Viewing musicking through this lens and drawing on music cognition and music technology, Sound Actions proposes a model for understanding differences between traditional acoustic “sound makers” and new electro-acoustic “music makers.” What is a musical instrument? How do new technologies change how we perform and perceive music? What happens when composers build instruments, performers write code, perceivers become producers, and instruments play themselves? The answers to these pivotal questions entail a meeting point between interactive music technology and embodied music cognition, what author Alexander Refsum Jensenius calls “embodied music technology.” Moving between objective description and subjective narrative of his own musical experiences, Jensenius explores why music makes people move, how the human body can be used in musical interaction, and how new technologies allow for active musical experiences. The development of new music technologies, he demonstrates, has fundamentally changed how music is performed and perceived.

At the core of the argument is the observation that the introduction of new music technologies has led to an increased separation between action and sound in musical performance. This has happened gradually, with pianos and organs being important early examples of instruments that introduced mechanical components between the performer and resonating objects. Today's network-based instruments represent an extreme case of a spatiotemporal dislocation between action and sound. They challenge our ideas of what an instrument can be, who can perform on them, and how they should be analyzed. In the lecture I will explain how we can use the concepts of action-sound couplings and mappings to structure our thinking about such instruments. This will be used at the heart of a new organology that embraces the qualities of both acoustic and electroacoustic instruments.

  Moving slowly likely puts us into a special state of mind. Subjective reports from various practices including dance, Tai Chi and walking meditation suggest that slow movements can bring participants into a special state involving increased relaxation and awareness. Interestingly, relatively little research has been performed specifically to understand the underlying mechanisms and the possible applications of human slow movement. One reason might be that slow movements are not common in day-to-day life: when we want to move – for example to pick up our cup of coffee - we usually want to do it now. Some evidence suggests that humans tend to avoid moving slowly in different tasks, for example, when improvising movements together. The goal of this meeting is to bring together scholars and practitioners interested in slow movement, and to foster interdisciplinary research on this somewhat neglected topic.

  What is the use of standing still for 10 minutes? I was asking myself when I saw a post on social media. It was a double picture of a man with a mobile phone around his neck displaying some data, and another picture showed the view he saw at that moment. I learned that he stood there for 10 minutes without any movement, listening to the sound that was already there. There were many pictures like this, and I decided to get in contact. So, today, we are in Oslo. We speak with Alexander Refsum Jensenius, a professor of music technology at the University of Oslo, a book author, a music researcher and researching musician working in the fields of embodied music cognition and new interfaces for musical expression. Alexander shares with us his experiences while performing and testing with artistic methods of embodied listening and how people experience music and sound. This goes from experiments with and without the conductor of a Symphony Orchestra to the sounds of our kitchen appliances. We talk about his motion capture lab, where a person’s exact location and micro-movements can be detected while they hear different kinds of music, and how the researchers can understand what moves them. Alexander shares insights about the Norwegian Championship of Stand Still, where until now, 1000s of people have participated, and the winner is the person with the lowest average velocity on standing the stillest over some time. Alexander explains the interplay of body and mind and reveals some secrets on how to move people, for example, on the dance floor or to calm them down. It all has to do with our bpm, the average heartbeat of about 60 beats a minute.

• Jensenius, Alexander Refsum (2022). Exploring music performance and perception through motion capture. Vis sammendrag

  This talk will present different approaches to capturing human bodily activity. Motion capture can be performed with sensor-based and camera-based systems, each of which has benefits and limitations. Sensor-based systems are flexible and scalable and can easily be used outside laboratory environments. They are good at tracking relative motion and rotation information but less suitable for tracking position. Camera-based systems come in many flavors and can be used with and without markers. They excel at tracking positions but are prone to reflections and environmental noise. As a consequence, camera-based motion capture systems are better suited for laboratory settings. I will discuss my twenty-year-long experience using different motion capture systems to study music-related body motion. This includes research on musicians, including rehearsal techniques and performance strategies. Such studies push the limits of the technology when it comes to precision and accuracy. It is particularly challenging when using motion capture equipment in real-world concert settings. At the University of Oslo, we have successfully captured the motion of both solo and ensemble performances and are currently trying to scale up to a full orchestra. We are also carrying out motion capture of perceivers, audience members in concerts, dancers, and other people moving to music. Through the Norwegian Championship of Standstill, we have delved into human micromotion, the tiniest actions we can perform and perceive. At this level, motion capture can detect physiological signals, such as breathing and heart rate. Data from such studies are interesting scientifically and have also been used in artistic practice. Finally, I will give examples of how real-time motion capture can be used in various creative applications, including "inverse" sonic interaction.

  In this project, we propose an algorithm to convert musical features and structures extracted from monophonic MIDI files to tactile illusions. Mapping music to vibrotactile stimuli is a challenging process since the perceptible frequency range of the skin is lower than that of the auditory system, which may cause the loss of some musical features. Moreover, current proposed models do not warrant the correspondence between the emotional response to music and the vibrotactile version of it. We propose to use tactile illusions as an additional resource to convey more meaningful vibrotactile stimuli. Tactile illusions enable us to add dynamics to vibrotactile stimuli in the form of movement, changes of direction, and localization. The suggested algorithm converts monophonic MIDI files into arrangements of two tactile illusions: “phantom motion” and “funneling”. The validation of the rendered material consisted of presenting the audio rendered from MIDI files to participants and then adding the vibrotactile component to it. The arrangement of tactile illusions was also evaluated alone. Results suggest that the arrangement of tactile illusions evokes more positive emotions than negative ones. This arrangement was also perceived as more agreeable and stimulating than the original audio. Although musical features such as rhythm, tempo, and melody were mostly recognized in the arrangement of tactile illusions, it provoked a different emotional response from that of the original audio.

In this talk, I will present some work leading up to the new agreement and how Universities Norway took a lead when developing the Norwegian Career Assessment Matrix (NOR-CAM). The core idea is that academics need to get recognition for a broader range of activities. This is important for transitioning to more open research practices and diverse career paths within and outside academia.

  This talk will reflect on my year-long project recording a daily "sound action". These are multimodal entities consisting of body motion and its resultant sound. When we only see a sound action, we can imagine its sound. If we only hear a sound action, we can imagine the body motion and objects involved in the interaction. Sound actions are ubiquitous in everyday life yet rarely discussed and reflected upon. My attempts at analyzing sound actions show some of the complexity involved in making sense of actions, reactions, and interactions with the world. This complexity can also inspire creative usage. I will present examples of meaningless and cognitively conflicting sound actions in the talk.

• Lesteberg, Mari & Jensenius, Alexander Refsum (2022). MICRO and MACRO - Developing New Accessible Musicking Technologies. Vis sammendrag

  This paper describes the development of two musical instrument prototypes developed to explore how non-haptic music technologies can be accessed from a web browser and how they can offer accessibility for people with low fine motor skills. Two approaches to browser-based motion capture were developed and tested during an iterative design process. This was followed by observational studies of two user groups: one with low fine motor skills and one with normal motor skills. Contrary to our expectations, we found that avoiding the use of buttons and mice did not make the apps more accessible for the participants with low fine motor skills. Furthermore, motion speed was considered more important for people with low motor skills than the size of the control action. The most important finding is that browser-based musical instruments using sensor-based and video-based motion tracking are not only feasible but allow for reaching much larger groups of people than previously possible. This may ultimately lead to both more personalized and accessible musical experiences.

  The paper presents the Musical Gestures Toolbox (MGT) for Python, a collection of modules targeted at researchers working with video recordings. The toolbox includes video visualization techniques such as creating motion videos, motion history images, and motiongrams. These visualizations allow for studying video recordings from different temporal and spatial perspectives. The toolbox also includes basic computer vision methods, and it is designed to integrate well with audio analysis toolboxes. The MGT was initially developed to analyze music-related body motion (of musicians, dancers, and perceivers) but is equally helpful for other disciplines working with video recordings of humans, such as linguistics, pedagogy, psychology, and medicine.
