The answer is both lovely and intentional. This is a new swing on a favorite childhood pastime, swinging on a swing set, one that makes music. Complete strangers in downtown Montreal simply hop onto a swing and begin to make beautiful music together. Enjoy theses 21 swings...with strings.

Oprah Winfrey on the OWN Network reports that:

Each spring, 21 multicolored swings are placed in the city's entertainment district, Quartier des Spectacles. Each seat acts as a musical instrument. As people swing, prerecorded sounds from pianos and other instruments fill the air. The more neighboring swings work together, the more melodies and harmonies begin to form.

How do we get these in our neighborhood?
