Tuning the Space
Performance as part of the informal review of our residency at Inter Art Center, Malmö, Sweden, 4 December 2020
Soeine: More of our thoughts about the project is in the INSPIRATIONS section.
Lars: The video below (electromagnetic inducer 2) shows our test of the feed back system with the inducer, a string, and a pickup microphone. I constantly had to feel the temperature with my finger to make sure it would not burn. We found that attaching strong neodymium magnets to the bolt made the inducer more efficient. We attached the the magnet "sideways" i.e. with the magnetic north pole pointing perpendicular to the direction of the bolt.
Lars: In the electromagnetic inducer 1 we test the same setup but with a tubular bells, instead. Here we attached a neodyme magnet to one of the bells to increase efficiency.
Lars: In the last video electromagnetic inducer experiment, we worked with strings loose in one end, somewhat similar to the Kalimba. We found it most effective to attach the magnet under the string so the magnet can vibrate freely in connection with the string.
Soeine: We started composing the space in the Red Room at Inter Art Centre.
Lars: Possibilities for feedback variations. We need an activator a resonator and a receiver to make a unit. The idea is to feed from one unit to another and back from the second to the first again to complete the circle. Which activators, resonators and receivers we select to make a unit and which units we pair together will naturally determine the timbres and musical possibilities of the piece. We think of as a matrix where we can compose by choosing different cross sections between the elements. Either a computer a mixer or a dancing body could facilitate the feedback process by making the pairings of the matrix during performance.
Soeine: We try to develop a device that self-generate sound through the vibrations of the strings. The vibration of the string will be picked up by a electro-magnetic pickup, and transferred to a computer and then to a speaker facing towards the string. Then the vibration from the speaker will vibrate the string and the whole process loops. Because the sound will be amplified, the amplified sound will be stopped by a command of computer program or by a performer, e.g., by holding the string to stop it from vibrating.
