  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.

  We present the results of a series of observation studies of ourselves standing still on the floor for 10 minutes at a time. The aim has been to understand more about our own standstill, and to develop a heightened sensitivity for micromovements and how they can be used in music and dance performance. The quantity of motion, calculated from motion capture data of a head marker, reveals remarkably similar results for each person, and also between persons. The best results were obtained with the feet at the width of the shoulders, locked knees, and eyes open. No correlation was found between different types of mental strategies employed and the quantity of motion of the head marker, but we still believe that different mental strategies have an important subjective and communicative impact. The findings will be used in the development of a stage performance focused on micromovements.

  This article presents the development of the improvisation piece Transformation for electric violin and live electronics. The aim of the project was to develop an “invisible” technological setup that would allow the performer to move freely on stage while still being in full control of the electronics. The developed system consists of a video-based motion-tracking system, with a camera hanging in the ceiling above the stage. The performer's motion and position on stage is used to control the playback of sonic fragments from a database of violin sounds, using concatenative synthesis as the sound engine. The setup allows the performer to improvise freely together with the electronic sounds being played back as she moves around the “sonic space.” The system has been stable in rehearsal and performance, and the simplicity of the approach has been inspiring to both the performer and the audience.

  We report on the development of a video based analysis system that controls concatenative sound synthesis and sound spatialisation in realtime in concert performances. The system has been used in several pieces, most recently Transformation for electric violin and live electronics, where the performer controls sound playback through motion on stage.

  Sverm-prosjektet avsluttes (i denne omgang) med en serie forestillinger i fourMs-lab’en ved Universitetet i Oslo. Her vil fokuset ligge på de fire elementene vi har jobbet med det siste året: stillstand, stillhet, mikrobevegelser og mikrolyd.
