Klarer du å stå stille til favorittlåta di? Prøv selv og vinn 1000kr!
Folk sier ofte at det er umulig å ikke bevege seg til musikk, men stemmer det?
Onsdag 3. april kan du teste deg selv når professor Alexander Refsum Jensenius – også kjent som Professor stillstand – inviterer til «NM i stillstand» her på Popsenteret.
Vinneren kåres samme kveld på LAB.prat #3 med nettopp Alexander! Her får du også vite mer om hva som faktisk skjer i kroppen når vi hører på musikk.
Som vanlig ledes kvelden av fasilitator og «MC» Dr. Kjell Andreas Oddekalv, også kjent som «Dr. Kjell» (eller hele Norges Kjelledegge som han selv liker å si) fra Hiphop orkesteret Sinsenfist. Sammen med Alexander inviterer han til en uformell samtale og Q&A om kroppsrytmer og hvordan de påvirkes av omgivelsene våre.
I tidsrommet mellom stillstandkonkurransen og LAB.prat er Popsenteret åpent og du er velkommen til å besøke utstillingen vår og alt den har å by på!

Hvorfor er noen musikalske og andre ikke? Hvordan har det seg at kunst kan treffe oss så voldsomt - og så ulikt! Ulike kunstneriske uttrykk som musikk, malerkunst, litteratur, dans og teater kommer uten fasit og tolkes vidt forskjellig fra person til person. Er det hjernen som styrer dette? Det er åpenbart at hjernen vår er aktiv og ikke passiv når vi opplever kunst. Hvorfor er det sånn? Gir kunstneriske opplevelser god hjernetrim? Er kunst viktig for hjernehelsen?

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.

The Power of Music Thinking.
Vis sammendrag
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 ̽ѡ. We speak with Alexander Refsum Jensenius, a professor of music technology at the University of ̽ѡ, 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.

Sound Actions: An Embodied approach to a Digital Organology.
Vis sammendrag
What is an instrument in our increasingly electrified world? In this talk I will present a set of theoretical building blocks from my forthcoming book on "musicking in an electronic world". 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.

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.

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.

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.

This paper addresses environmental issues around NIME research and practice. We discuss the formulation of an environmental statement for the conference as well as the initiation of a NIME Eco Wiki containing information on environmental concerns related to the creation of new musical instruments. We outline a number of these concerns and, by systematically reviewing the proceedings of all previous NIME conferences, identify a general lack of reflection on the environmental impact of the research undertaken. Finally, we propose a framework for addressing the making, testing, using, and disposal of NIMEs in the hope that sustainability may become a central concern to researchers.

The potential of Citizen Science is high on the agenda in the discussion on the future of academic research. The European Commission’s Communication “A new ERA for Research and Innovation”, published in September 2020, states that “[...] the engagement of citizens, local communities and civil society will [help] achieve greater social impact and increased trust in science.” Citizens can contribute in diverse ways, ranging from data collection over data analysis to co-designing projects, and thereby bring academic research and its outcomes closer to society.
However, Citizen Science also accentuates ethical and legal questions about ownership of the research process and outcomes, and poses challenges in terms of safeguarding research quality. Addressing these challenges and using the opportunities of Citizen Science will require universities to take the lead and consider the place of Citizen Science within their institutional strategies, as well as the support they offer to research staff.
Engaging in inclusive and transparent science, Citizen Science and Open Science are becoming increasingly intertwined. Currently, Citizen Science is described by the European Commission as “both an aim and enabler of Open Science”.
This joint workshop will discuss themes around institutional support for Citizen Science and offers an opportunity to transfer and share knowledge. The aim is to exchange experiences, lessons learnt, and explore common challenges. To support Citizen Science, the online workshop will discuss tools, guidelines and good practices from Open Science experiences as well. Participating universities will have the opportunity to share expertise, coordinate efforts and exchange advice on services, tools and legal and ethical issues.

Standstill to the ‘beat’: Differences in involuntary movement
responses to simple and complex rhythms.
Vis sammendrag
Previous studies have shown that movement-inducing properties of music largely depend on the rhythmic complexity of the stimuli. However, little is known about how simple isochronous beat patterns differ from more complex rhythmic structures in their effect on body movement. In this paper we study spontaneous movement of 98 participants instructed to stand as still as possible for 7 minutes while listening to silence and randomised sound excerpts: isochronous drumbeats and complex drum patterns, each at three different tempi (90, 120, 140 BPM). The participants’ head movement was recorded with an optical motion capture system.We found that on average participants moved more during the sound stimuli than in silence, which confirms the results from our previous studies. Moreover, the stimulus with complex drum patterns elicited more movement when compared to the isochronous drum beats. Across different tempi, the participants moved most at 120 BPM for the average of both types of stimuli. For the isochronous drumbeats, however, their movement was highest at 140 BPM. These results can contribute to our understanding of the interplay between rhythmic complexity, tempo and music-induced movement.

I will present the spatiotemporal matrix, a system for categorizing human actions into different spatial and temporal levels: micro, meso, macro. Most regular human actions would be categorized as meso-meso, that is, medium-sized motion within a timespan that fits our short-term memory. Exploring combinations of micro and macro levels in both space and time is challenging, but is also conceptually, practically and artistically interesting. I will show an example of this from the music-dance performance Sverm, and explain how the matrix was informed by my research into the effect of music on the micromotion observed when people try to stand still.

We present an approach to analyzing the motion capture data ofrowers using bivariate functional principal component analysis(bfPCA). The method has been applied on data from six elite rowersrowing on an ergometer. The analyses of the upper and lower bodycoordination during the rowing cycle revealed significant differences between the rowers, even though the data was normalized toaccount for differences in body dimensions. We make an argumentfor the use of bfPCA and other functional data analysis methods forthe quantitative evaluation and description of technique in sports.

INTIMAL is an interactive system for relational listening, which integrates physical-virtual interfaces for people to sonically improvise between distant locations. The aim is to embrace two key aspects in the context of human migration: the sense of place and the sense of presence. This paper reflects on the use of INTIMAL in a long-distance improvisation between the cities of ̽ѡ, Barcelona and London in May 2019. This improvisation was performed by nine Colombian migrant women, who had been involved in a research process using the Deep Listening® practice developed by Pauline Oliveros. Here we describe the performance setting and the implementation of the first two interfaces of the system: MEMENTO, an “embodied” navigator of an oral archive of Colombian women’s testimonies of conflict and migration; and RESPIRO, a sonification system that transmits and sonifies live, breathing signals between distant locations. We reflect on how the two interfaces facilitated and challenged the improvisers’ listening experiences and connections.

In this installation we explore how six self-playing guitars can entrain to each other. When they are left alone they will revert to playing a common pulse. As soon as they sense people in their surroundings they will start entraining to other pulses. The result is a fascinating exploration of a basic physical and cognitive concept, and the musically interesting patterns that emerge on the border between order and chaos.

This workshop is intended to discuss how we think about and handle research ethics at NIME conferences. A number of NIME papers involved studies on/with humans. Most of these are on volunteering adults, but there are also examples of studies with children, and with patients. We also see an interest in the community to carry out research on/with animals. NIME’s current ethical guidelines do not take these perspectives into account. The Steering Committee therefore sees the need to develop better and more up-to-date ethical guidelines for the conference. This is to create an increased awareness about the needs for ethical considerations in the community, but also as guidelines for reviewers and conference chairs. NIME is proud of being a very heterogeneous community, covering people working in a large number of different scientific disciplines, artistic practices, as well as R&D in the industry. Needless to say, this breadth of perspectives also means that it is difficult to impose the same guidelines on all studies. NIME researchers also have to abide to a number of different regulations at institutional, regional, national, continental and international levels. The workshop will consist of short introductions to some challenges faced when carrying out research on/with humans and animals, in both scientific and artistic contexts. This will be followed by group-based brainstorming and a final plenary discussion.

The influence of acoustic stimuli and feedback in sport has been explored as means of optimizing technique, in particular during training. Interactive and adaptive acoustic systems have been evaluated for rowing, with results showing a significant increase in boat velocity. However, assessment of the effects of acoustic feedback and pacing in the technical aspects of rowing is still scarce. Previous studies on the smoothness of the stroke force profile have shown that smoothness metrics can qualitatively reflect movement coordination. In this study, we quantify and compare hand movement smoothness from rowers performing under three acoustic conditions: silence, verbal instructions, and acoustic pacing.

This workshop is intended for discussing how we can develop more and better strategies and tools for opening up research processes and results within the NIME community. The development of more openness in research has been in progress for a fairly long time, and has recently received a lot of more political attention through the Plan S initiative, The Declaration on Research Assessment (DORA), EU's Horizon Europe, and so on. The NIME community has been positive to openness since the beginning, but still has not been able to fully explore this within the community. We call for a workshop to discuss how we can move forwards in making the NIME community (even) more open throughout all its activities.

Is it possible to do experimental music research completely openly? And what can we gain by opening up the research process from beginning to end? In the talk I will present MusicLab, an open research project at the University of ̽ѡ. The aim is to explore new methods for conducting research, research communication, and education. Each MusicLab event is organized around a public music performance, during which we collect data from both musicians and audience members. Here we explore different types of sensing systems that work in real-world contexts, such as breathing, heartbeat, muscle tension, or motion. The events also contain an edutainment element through panel discussions as well as "data jockeying" in the form of live data analysis. The collected data is made publicly available, and forms the basis for further analysis and publications after the event. Opening up the research process is conceptually, practically, and technologically challenging for everyone involved. The benefit is that it has helped us solve a number of issues when it comes to GDPR and copyright. It has also pushed our research in directions that we previously had never thought about, and helped us communicate this to new users.

In this paper, we present a course of audio programming using web audio technologies addressed to an interdisciplinary group of master students who are mostly beginners in programming. This course is held in two connected university campuses through a portal space and the students are expected to work in cross-campus teams. The workshop promotes both individual and group work and is based on ideas from science, technology, engineering, arts and mathematics (STEAM), team-based learning and project-based learning. We show the outcomes of this course, discuss the students’ feedback and reflect on the results. We found that it is important to provide individual vs. group work, to use the same code editor for consistent follow-up and to be able to share the screen to solve individual questions. Other aspects inherent to the master (intensity of the courses, coding in a research-oriented program) and to prior knowledge (web technologies) should be reconsidered. We conclude with a wider reflection on the challenges and potentials of using web audio as a programming environment for beginners in STEAM and distance-learning courses.

What is an instrument in our increasingly electrified world? In this talk I will present a set of theoretical building blocks from my forthcoming book on "musicking in an electronic world". 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.

This presentation will summarize findings from my research into music-related micromotion. This includes the smallest human motion that we can perform and perceive, typically measured at at a scale of millimeters. We have carried out a series of studies of such micromotion, in which people have been asked to try to stand still on the floor, both in silence and with (musical) sound. By measuring their bodily responses with different types of motion tracking and physiological devices we find a number of similarities between people's quantity and quality of motion. This has been the starting point for exploring the use of micromotion in musical practice, what I call 'sonic microinteraction'. This includes standstill performances with interactive sound and light. It also includes several installations with our ensemble of self-playing guitars. These are hybrid instruments, using digital sound-production through acoustically resonating guitars. They are controlled through inverse microinteraction, meaning that you need to focus on standing still to produce any sound. This challenges our traditional understanding of the affordance of musical instruments, and opens for both artistically and scientifically interesting perspectives.

"Ellos no están entendiendo nada" ("They are not understanding anything"): Listening to Embodied Memories of Colombian Migrant Women Reflecting on Conflict and Migration.
Vis sammendrag
Exploring the role of the body as an interface that keeps memory of place, INTIMAL physical-virtual “embodied” system, integrates body movement, voice, and an oral archive, as an artistic platform for relational listening (Alarcón, 2019), using networking technologies for telematic sonic improvisatory performances, in the context of geographical migration. INTIMAL has been informed by a case study with nine Colombian migrant
women in Europe, listening to their migrations, and to an oral archive with testimonies of conflict and migration by other Colombian migrant women.1 The first two interfaces created for the system: MEMENTO (a spoken word retrieval system), and RESPIRO (for transmission and sonification of breathing data), have been tested by the research participants in a telematic sonic improvisatory public improvisatory performance between the cities of ̽ѡ, Barcelona, and London. In the performance, proposed as a shared dream, a “complex narrative” (Grishakova & Poulaki, 2019) emerged, for both the improvisers and the audiences. In this paper, we describe the conditions of the narrative environment, and the embodied expressions that
emerged—including body movement, voice, spoken word, and breathing—establishing connections between gendered migration, and Colombian conflict. We reflect on how distributed improvisatory embodied
expression, and relational listening through technological mediations, aids the process of collective remembering (Wertsch, 2001), in a complex context of conflict and migration.

This exploratory study investigates muscular activity characteristics of a group of audience members during an experimental music performance. The study was designed to be as ecologically valid as possible, collecting data in a concert venue and making use of low-invasive measurement techniques. Muscle activity (EMG) from the forearms of 8 participants revealed that sitting in a group could be an indication of a level of group engagement, while comparatively greater muscular activity from a participant sitting at close distance to the stage suggests performance-induced bodily responses. The self-reported measures rendered little evidence supporting the links between muscular activity and live music exposure, although a larger sample size and a wider range of music styles need to be included in future studies to provide conclusive results.

How music moves us? Studying human body micromotion in music perception.
Vis sammendrag
Music has the power to influence not only our thoughts and emotions, but also various physiological processes in our bodies. Furthermore, it often encourages physical movement of the listener. While there are numerous studies describing spontaneous psychophysiological responses to music that are linked with emotions, spontaneous body movement to music has became a topic of exploration relatively recently. Mostly, it has been studied in the context of free dance (Burger et al., 2013) or synchronization to musical rhythm while performing repetitive movements such as walking (Styns et al., 2007). But what can we observe if the participants are just standing still? In our project “MICRO - Human Bodily Micromotion in Music Perception and Interaction” we focus on movements so small that they can be unnoticed both by observer and performer, and that can happen involuntarily. This is what we call “micromotion” of the human body. To see how these small movements are affected by music, we develop different experiments using mainly motion capture technology, but also physiological measures such as electromyography (EMG). In this presentation I would like to describe some of our research methods, findings and plans.
In one of the experiment paradigms, disguised as the “Norwegian Championship of Standitill”, we invite groups of participants to the laboratory and ask them to stand as still as possible while we present them with segments of selected music or silence. The head motion of each participant is captured using an infrared optical system. In 2012, 91 subjects stood on the floor for 3 minutes in silence and 3 minutes listening to music of increasing level of rhythmicality and energy (Jensenius et al., 2017). In 2017, 71 participants listened to 6 minutes consisting of segments of silence alternating with electronic dance music (EDM), classical Indian music or Norwegian fiddle music. In both studies we observed higher mean quantity of motion of the participants (QoM) in music condition compared to silence condition, and the effect was driven mostly by EDM. We also observed correlations between QoM and participant’s age, height and standing strategy (locked knees), although these results are mixed between the two studies. The future goal is to look more closely into specific features in music that correspond with observed movement, to search for signs of rhythmic entrainment, and to see what demographic and psychological factors might contribute to interpersonal differences in music induced body micromotion.

This article describes the design and construction of a collection of digitally-controlled augmented acoustic guitars, and the use of these guitars in the installation \textit\{Sverm-Resonans\}. The installation was built around the idea of exploring `inverse’ sonic microinteraction, that is, controlling sounds by the micromotion observed when attempting to stand still. It consisted of six acoustic guitars, each equipped with a Bela embedded computer for sound processing (in Pure Data), an infrared distance sensor to detect the presence of users, and an actuator attached to the guitar body to produce sound. With an attached battery pack, the result was a set of completely autonomous instruments that were easy to hang in a gallery space. The installation encouraged explorations on the boundary between the tactile and the kinesthetic, the body and the mind, and between motion and sound. The use of guitars, albeit with an untraditional `performance’ technique, made the experience both familiar and unfamiliar at the same time. Many users reported heightened sensations of stillness, sound, and vibration, and that the `inverse’ control of the instrument was both challenging and pleasant.

Introduction
Postural stability have been the focus of a number of studies on fall prevention and sports, with an emphasis on walking dynamics1 . Fewer studies have aimed at understanding the influence of sound stimuli in standing posture sway 2.
Although the vestibular system plays a fundamental role in the control of postural stability, it has also been shown to be key in embodied cognition processes 3. It is in part through the vestibular system that music activates motor areas in the brain to induce movement, while body movement enhances the cognitive processing of sound and music 3.
This study explored the influence of music on postural control by measuring synchronization between body center of mass (COM) sway with music.
Methods
7 women (32 ± 4.39 years, 1.73 ± 0.04 m, mean ± SD), and 5 men (29.67 ± 4.63 years, 1.81 ± 0.04 m) participated in the study. Participants were asked to stand still for 6 minutes as they were presented with alternating segments of silence and music. COM movements were measured from the position of a passive marker placed in the midline of the sacrum, recorded using an infrared motion capture system. Radial and vertical COM movements were cross-correlated with the pulse clarity, RMS, and spectral centroid of the stimuli.
Results
Paired samples t-test revealed differences in COM radial and vertical sway between silent and music conditions to be significant at the 0.05 level.
A repeated measures ANOVA showed a significant effect of the stimuli on COM sway (p < 0.05).
The effect of the stimuli on the lag of maximum cross-correlation (delay) between COM radial sway and RMS was shown to be significant (p < 0.05). Differences in delay between pulse clarity and COM vertical sway were significant between stimuli (p < 0.05 ).
Discussion
Results suggest that the effect of RMS in music-induced postural sway might be predominant in the radial plane, with anticipatory behavior observed for stimuli with low RMS.
Vertical sway correspondence patterns suggest anticipatory vertical motion to music spectral centroid.
A more robust understanding of a range of music features and their links with induced movement could lead to insight into the role of the vestibular and sensory systems in balance control.

Stillness under Tension.
Vis sammendrag
Stillness Under Tension is an ensemble standstill work for Myo gesture control armband and Bela embedded music platform. Humans are incapable of standing completely still due to breathing and other involuntary micromotions. This work explores the expressive space of standing still through an inverse action-sound mapping: less movement leads to more sound. Four performers stand as still as possible on stage, each wearing a Myo armband connected to a Bela embedded sound processing platform. The Myo is used to measure the performers movement, and the muscle activity in their forearm which they can use--both voluntarily and involuntarily--to control a synthesised sound world. Each performer uses one Myo and Bela in a musical space defined by their physical position and posture while standing still.

An installation that gives you access to heightened sensations of stillness, sound and vibration.
Approach one of the guitars. Place yourself in front of it and stand still. Feel free to put your hands on the body of the instrument. Listen to the sounds appearing from the instrument. As opposed to a traditional instrument, these guitars are “played” by (you) trying to stand still. The living body interacts with an electronic sound system played through the acoustic instrument. In this way, Sverm-Puls explores the meeting points between the tactile and the kinesthetic, the body and the mind, and between motion and sound.

Vi lever i en spennende tid, med stadig nye varianter av både akustiske og elektroniske instrumenter. Disse passer sjelden inn i de tradisjonelle organologiske fremstillingene, noe som gjør at det er behov for en mer systematisk diskusjon av hvordan man kan klassifisere både instrumenter (i utvidet forstand) og dere spilleteknikk. I denne presentasjonen vil jeg forklare hovedelementene i en ny organologi som jeg holder på å utvikle, med utgangspunkt i det jeg kaller "handling-lyd-koblinger".

Sverm-Resonans.
Vis sammendrag
En installasjon som gir deg tilgang til stillstand, lyd og vibrasjon.
Stå stille. Lytt. Finn lyden. Beveg deg. Stå stille. Lytt. Hør spenningen. Kjenn på bevegelsene dine. Slapp av. Stå enda stillere. Lytt dypere. Føl på grensen mellom det kjente og det ukjente, det kontrollerbare og det ukontrollerbare. Hvordan møter kroppen lyden? Hvordan møter lyden kroppen? Hva hører du?
Gå bort til en av gitarene. Plasser deg fordan den og kjenn på stillstanden din. Hvis du vil kan du plassere hendene på instrumentet. Forsøk å lukke øynene. Åpne sansene for lydvibrasjonene du føler og hører. Stå så lenge du vil og kjenn på utviklingen av lyden, og dine indre opplevelser, bilder og assosiasjoner. I motsetning til et tradisjonelt instrument "spilles" disse gitarene ved at du står stille. Den levende kroppen interagerer med et elektronisk lydsystem spilt gjennom et akustisk instrument. Sverm-resonans utforsker møtepunktet mellom det taktile og det kinesiske, kroppen og sinnet, og mellom bevegelse og lyd.

This paper explores sonic microinteraction using muscle sensing through the Myo armband. The first part presents results from a small series of experiments aimed at finding the baseline micromotion and muscle activation data of people
being at rest or performing short/small actions. The second part presents the prototype instrument MicroMyo, built around the concept of making sound with little motion. The instrument plays with the convention that inputting more energy into an instrument results in more sound. MicroMyo, on the other hand, is built so that the less you move, the more it sounds. Our user study shows that while such an "inverse instrument" may seem puzzling at first, it also opens a space for interesting musical interactions.

In order to understand how we perceive music, we should always consider that this process starts in our bodies being exposed to sound. Thus, the cognitive processing of sound cannot be treated as separate from the functioning of the body. During the last decades there has been a growing focus on embodied music cognition, and the role of the human body in both perception and production of music has been widely studied. However, not much research has been devoted to what we might call “micromotion” of the human body in the musical context – the tiniest, often involuntary and unconscious movements that occur during music listening. The human body is never completely still as there are many physiological processes that induce small-scale movement. The question, then, is whether such micromotion is altered when we are exposed to music? Here I would like to present my design of a set of small experiments that will shed some light on how human micromotion is influenced by musical sound. Methodologically, I will use a combination of motion capture and portable eye-tracking glasses. Each experiment will be designed to test a different subject, such as the differences between listening to music via headphones and via loudspeakers or the importance of the low-frequency region (bass sound) in inducing body movement. The aim of these small and exploratory studies will be to understand more about the effects of musical sound on human micromotion in particular and music cognition in general.

Micro, Meso, Macro: Music-related body motion at different spatiotemporal levels.
Vis sammendrag
Performance of acoustic instruments is often happening at a spatiotemporal micro-level. Violin performance, for example, is based on an extreme control of the spatial placement of the left-hand fingering and the right-hand bow strokes. Even though there are exceptions, many digital musical instruments (DMIs) are based on meso- or macro-level control, that is, fairly large and slow control actions compared to acoustic instruments. In this talk I will present a theoretical framework for sound-producing actions and a related organological model. This will be exemplified with some of my empirical results of music-induced dancing, "air instrument" performance and sonic microinteraction.

This presentation will focus on my research on human micromotion in musical contexts. My scientific research has focused on understanding more about the phenomenon of human standstill and how music influences our micromotion when standing still. My artistic research has focused on the exploration of micromotion in music and dance performance, and particularly how it is possible to set up systems for sonic microinteraction. My two separate "tracks" of research, the scientific and artistic, have positively reinforced each other, shedding light on a level of musical expressivity on the boundary between the conscious and the unconscious, the voluntary and the involuntary.

Exploring Music-related Micromotion in the Artistic-Scientific Research Project Sverm.
Vis sammendrag
This presentation will focus on my work on human micromotion in musical contexts. My scientific research has focused on understanding more about the phenomenon of human standstill and how music can influence our micromotion when standing still. My artistic research has focused on the exploration of micromotion in music and dance performance, and particularly how it is possible to set up systems for artistic microinteraction. Most importantly, even though it makes sense to talk about these as two separate "tracks" of research, the scientific and artistic, they have in fact been highly intertwined. It would not have been possible to achieve neither the scientific nor artistic outcomes without a true artistic-scientific research process.

This paper reports on a study of how music influences people standing still, with the aim to investigate: (a) How (much) people move when standing still in silence? (b) How (much) musical sound influences people's standstill?
A total of 103 participants (mean age 25 years, equal gender balance) were recruited to the study, which was presented as a "championship" of standstill. The participants each wore a reflective marker on their head, and its position was recorded using a state-of-the-art motion capture system. The task was to stand still on the floor for 6 minutes, 3 minutes in silence and 3 minutes with music. The musical stimuli were 7 excerpts of 20-40 seconds duration, ranging from slow, non-rhythmic music for the first excerpts to dance music at the end. After omitting subjects with with incomplete data sets, 91 participants have been included in the study.
The analysis shows that the average quantity of motion (QoM), calculated as the cumulative distance travelled for each of the head markers, was 6.5 mm/s (std: 1.6 mm/s) for the entire data set. For the 3-minute parts without music we found an average QoM of 6.3 mm/s (std 1.4 mm/s), as opposed to 6,6 mm/s (std 2,2 mm/s) for the part with music. The results are even more clear when looking at individual stimuli, with a QoM of 6,8 mm/s (std 2,3 mm/s) for the last dance music example. Contrary to our expectations, no particular spatiotemporal differences were found in the motion patterns for different musical excerpts.
The study confirmed the level of micromotion found in human standstill (6.5 mm/s QoM) found in our previous longitudinal studies. The study also confirmed our expectation that people spontaneously move to music, even when specifically trying to stand still. The study did not, however, confirm any spatiotemporal differences for the different musical material. Future studies will include looking systematically at how musical features influence both the quantity and quality of standstill.

Hvorfor beveger du deg til musikk? Hva er det med dansemusikk som får deg til å danse? Hvor stille sitter du egentlig på en klassisk konsert? Alexander Refsum Jensenius vil svare på disse spørsmålene og fortelle mer om sin forskning på luftgitarister, discodansere, pianister og dirigenter. Utgangspunktet for forskningen er erkjennelsen av at musikkopplevelsen i bunn og grunn er kroppslig fundert. Vi opplever ikke musikk bare med ørene, alle sansene er involvert når vi "lytter". Ved å bruke bevegelsessporing som metode, er det mulig å systematisk studere hvordan folk responderer på musikk. Resultatet er ny kunnskap om musikalsk mening, fra et kroppslig perspektiv.

The goal of this thesis was to develop and experiment with a set of sonification tools to explore participant data from standstill competitions. Using data from the 2012 Norwegian Championship of Standstill, three sonification models were developed using the Max/MSP programming environment. The first section of the thesis introduces sonification as a method for data exploration and discusses different sonification strategies. Momentary Displacement of the position was derived from the position data and parameter mapping methods were used to map the data features with sound parameters. The displacement of position in the XY plane or the position changes along the Z-Axis can be mapped either to white-noise or to a sine tone. The data variables control the amplitude and a filter cut-off frequency of the white noise or the amplitude and frequency of the sine tone. Moreover, using sound spatialization together with sonification was explored by mapping position coordinates to spatial parameters of a sine tone. A “falling” effect of the standing posture was identified through the sonification. Also audible were the participants’ breathing patterns and postural adjustments. All in all, the implemented sonification methods can be effectively used to get an overview of the standstill dataset.

Today, there are several toolboxes which can work on audio, motion, or other sensor data. These toolboxes are very useful to provide characteristic analysis of audio and motion. Unfortunately, the analysis is done separately by different toolboxes. This results in inconvenience when we want to work on these data simultaneously. So developing a toolbox which integrates the existing toolboxes is necessary. The main goal of the project is to integrate these toolboxes in Matlab and provide video analysis combined with audio and motion capture data. This would be important for our interdisciplinary research on music and motions through fourMs as well as for external work on e.g. analyzing video recording for early child diagnosis of cerebral palsy. This project presents the development of a toolbox for Matlab entitled “Musical Gestures (MG) Toolbox”. This toolbox is aimed for solving pressing needs for the video analysis of music-related body motion since video source recorded by regular video camera is a very good option for studying motion. The term music-related body motion refers to all sorts of body motion found in music performance and perception. It has received a growing interest in music research and behavioral science over the last decades. Particularly, with the rapid development of modern technology, various motion capture systems make it possible to further study music-related body motion. Matlab has been chosen as the platform since it is readily available, and there are already several pre-existing toolboxes to build on. This includes the “Motion Capture (MoCap) Toolbox” [1] developed for the analysis and visualization of Motion Capture data, which is aimed specifically for the analysis of music-related body motion. The “Music Information Retrievel (MIR) Toolbox” [2] is another relevant toolbox, which is developed for the extraction of musical features from audio data and the investigation of relationships between sound and music features. While the two above mentioned toolboxes are useful for studying motion capture data and audio, respectively, they are very differently designed, and it is not possible to make combined analysis of audio and motion capture data. Furthermore, there is no integration with video analysis. The MG Max toolbox [3] has been developed for music-related video analysis in the graphical programming environment Max/Msp/Jitter, with a number of novel visualization techniques (motiongrams, motion history images, etc.). These techniques are commonly used in music research, but are not currently available in Matlab. The main contributions of this project consist of two following things. One is to integrate the MoCap toolbox and MIR toolbox, and provide simple preprocessing on different input data. Another is to provide several video analysis techniques to study music-related body motion in the toolbox. These video analysis techniques include motiongram, optical flow, eulerian video magnification. With these techniques, the developed MG toolbox for Matlab could provide reliable and quantitative analysis of music-related body motion based on video.
