MECHANICAL ADDITIVE SYNTHESIS

The installation is based on the concept of combining multiple sound sources to create new waveforms and acoustic interactions.
Commonly, this is achieved through the addition of digital or analogue sound sources.
Instead, this installation replaces these sources with actual mechanical resonators, which can be controlled by up to six users simultaneously.
To enhance the acoustic coupling, the resonators are mounted on two metal sheets, which also work as giant membranes.
By carefully adjusting the speed of the motors, the users can create resonances and dissonances.
Thus, listening to each other and reacting with attention enables the users to create soundscapes varying from ambient noise to heavy drones.
