“21 Swings” installation in Montreal by Daily Tous Les Jours (Source: thekhooll)

The result is a giant collective instrument made of 21 musical swings; each swing in motion triggers different notes, all the swings together compose a piece, but some sounds only emerge from cooperation. The project stimulates ownership of the new space, bringing together people of all ages and backgrounds, and creating a place for playing and hanging out in the middle of the city centre.
