OYFO Techniekmuseum, Hengelo, April – August, 2022

Piano / Forte is a sound sculpture in which two piano harps – two pianos stripped of keyboards and supporting parts – swing in the air like pendulums. Inside the pianos, a sensor (accelerometer) measures the variations of x, y, z positions, communicating with a custom made software that translates the motion into sound frequencies. These frequencies are sent back into the pianos via electromagnets (transducers) attached to the harps. Instead of being hammered by keys, the sound is generated by the transducers vibrating directly onto the piano’s body, resulting in a multitude of resonances and reverberations.

Piano / Forte is another collaboratior with Rob Bothof. Thanks to Jimi Hellinga for the recordings.
