Two fabric loops, driven by a motor divide space. At certain points there are light sensors installed to receive signals from the opacity of the textile, which get translated into audio signals.The musicality of the instrument can be experienced by sliding or positioning the sensor across the fabric tracks. It works as Mediaperformance as well as an interactive sound art installation.
Musicality and design
Fabrics which differ in their weaving technique, are sewed one after another (each loop consists of 196 inch length, with a width of 4,2 inch), creating a fabric track.
The basic parameters which take influence on the sound generation and can be chosen by playing consist of the following:
- The tone pitch is created by the quality of the fabric, weaving tecnique, basically this is the amount of threads interrupting the light per second.
- Breaks and rhythm are due to the seam, and the length of each sort of fabric.
- The arrangement of the fabrics in aspects of lenght, quality and the connecting seams are additive parameters for composing a rhythm or a flowing change of the tone pitch .
For the playing tecnique the positioning of the LED at the top of the fabric and the Photodiode at its botton is important to take influence on the sound performance.
Sliding, lifting and approaching gives certain effects.
By varying the speed of the motors and the distance between Led and fabric I set up different rhymic lines and combine it with different frequencies with the other led. One loop is more focused on rhytmic elements, while the other plays with pitch.
