Technology advances enable the creation of new music instruments. Unlike traditional instruments, which produce a particular range of sounds and are designed to be played a particular way, the technology of these new music instruments is flexible and formless, taking shape only when its players decide how they are going to use them. The sounds these instruments produce and even the shapes they assume is open to be interpreted by their players, with new technology allowing non traditional dimensions such as the texture of a material employed or the way the movements of the executor are mapped into sound. Rather than a pre defined skill set that must be learned, the technology is intuitively understood, so that users can instantly enjoy 'knowing' how to play, while the openness of a hackable design encourages virtuosity. In this talk, Bruno Zamborlin of Mogees will explore these new wave of instruments “designed to be hacked”, and their power as interactive tools for creative expression.
