In the gardens of the Fine Arts Museum, a piano stands proudly next to the fountain. Keys of Light is an interactive installation which uses a combination of algorithms to project a light show on the façade and gardens every time a key is pressed. The show changes every evening depending on the melody chosen. The abstract patterns reveal the architectural splendour of the building, and highlight statues and trees. The pianist, emboldened to further explore the shared harmony between music, light and architecture, composes his own score and brings the musical notes to life/light.
