Our idea starts from the necessity to investigate space, to explore its features, finding the potential in acoustic properties and using them as a starting point for our research. How is it possible to create a three-dimensional and analogue sound system? How are we able to work with instruments that can move sound in space? Taking advantage from the use of customised industrial items, we will have the possibility to create three-dimensional audio images controlled and designed in real time by the performers. The concept that interests us is the single percussive impulse as music creator. We can change surface, speed of execution but the impulse is at the core of every percussive action.
