Orchestral maneuvers in the square—this interactive pavement turns a new public plaza into the stage for one big impromptu musical ensemble. Anchoring the publicly accessible courtyard of a new mixed-use development called the Gaslight District, a wave-patterned pavement embedded with 62 light rings and sensors becomes a joyful exercise in musical collaboration.

Set only a short distance away from the Grand River, 'River Lines' shifts the city’s attention back to its long neglected waterfront, its design and musical score highlighting how for more than a century the river has been central to the rhythms of community life.

With different instrument sections (kalimba, piano, guitar, kora, harp, violin) assigned to positions across the pavement’s surface, players connect the dots to create arpeggiated clusters of notes that harmonize along with the playing of others to create one rich tapestry of music.
