Metáforas Para Pianos Muertos [Metaphors for dead pianos] is a long-term exploration using old piano parts. Each iteration of the installation/performance is different, however, all share the same logic; searching for nuances and particularities of the objects and generating organic improvisations with the hidden sonorities, creating a dialog between the piano parts, the performer, and the space that embrace the installation. In all the versions, custom electronics are fabricated in order to control and manipulate actuators, motors and electromagnets that allows the generation of string vibrations.
