The Swings were created by a Montreal-based interactive design studio called Daily tous les jours and the original set of 21 swings has been set up in the Quartier des spectacles area in Montréal, where every day each swing has swung an average of 8,500 times.

According to Daily tous les jours' website, "the Swings allow participants to make music with their entire bodies, to connect to one another and to have a sense of ownership of public space due to the music they create. The result is a giant collective instrument that brings together people of all ages and backgrounds."
Each swing makes the sound of a guitar, piano, vibraphone, or harp and riders can create can make harmonies by swinging in synch.
