Plan for Making the Instruments

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.

Lars: Another parameter determining the feedback between the two units is their tonal relation. If they are tunes to have overtones in common the feedback will rise, if not the feedback dies out.
A special case is the dripping bottles, which we treat as a rhythmical element rather than a tonal. "Tuning the drops" means adjusting the speed of the dripping. This can be done by filling more or less water into the bottle whereby the water pressure increases/decreases.
