21 Swings is a giant interactive instrument that uses swings to trigger different musical notes. Located in center of Montreal, Canada for Quartier des Spectacles, the swings are open to the public. When the swings are used individually they produce single notes, but when they are used together melodies begin to emerge. Some combinations of notes can only be achieved with cooperation of all the swings.
Developed by Montreal collective Daily Tous les Jours, the project shows the positive effects that can come from people working together. It also highlights that no matter how old you are, swings bring out the kid in everyone.
