Marco Buongiorno Nardelli has started the miniature opera project from the idea of making space become an interactive score and of allowing the audience to create unique musical sequences by acting directly on a physical art piece. These installations are designed as a large interactive electronic “game boards” made of numerous “electronic tiles” that can be connected to each other in a completely reconfigurable way. Each tile contains a light sensor that triggers a unique sound event when covered. Among the electronic tiles, we place “word (or guide) tiles”, typically marked with specific words or characters’ names, to provide the participants with a stage for an operatic libretto. The audience is then invited to create connections between guide tiles by placing bean bags on the tiles of their choice, thus activating the light sensor circuit and starting the associated musical gesture. The miniature opera project installations are first and foremost “games” for the audience, whose reward is the creation of a unique piece of music that they will be able to bring home on their own portable device.
